[IOS]非常不错的导航控制器的应用Demo
2023-09-27 14:29:23 时间
我们在iPhone开发的过程中，估计UINavgationController是最最常用的控件之一吧，截下来我就用一个demo来举例导航控制器的应用。包含了tableview中增删查改的功能。
导航控制器的应用Demo 实现步骤： 1.创建一个Empty项目，命名为Navdemo。 2.创建一个根视图控制器，继承自UINavgationController，命名为FirstViewController。
#import UIKit/UIKit.h @interface FirstViewController : UITableViewController @property(nonatomic,retain) NSMutableArray *array; @end
FirstViewController.m:
#import "FirstViewController.h"
#import "DXWDiscosureButtonViewController.h"
#import "DXWCheckViewController.h"
@interface FirstViewController ()
@implementation FirstViewController
static NSString *CellIdentifier = @"Cell";
- (id)initWithStyle:(UITableViewStyle)style
self = [super initWithStyle:style];
if (self) {
self.array = @[[[DXWDiscosureButtonViewController alloc] initWithStyle:UITableViewStylePlain],[[DXWCheckViewController alloc] initWithStyle:UITableViewStylePlain]];
self.title = @"First";
return self;
- (void)viewDidLoad
[super viewDidLoad];
//注册
[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:@"Cell"];
- (void)didReceiveMemoryWarning
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
#warning Potentially incomplete method implementation.
// Return the number of sections.
return 1;
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
#warning Incomplete method implementation.
// Return the number of rows in the section.
return [self.array count];
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
//[tableView registerClass:[SecondViewController class] forCellReuseIdentifier:@"aa"];
//这个多一个最后的一个参数，必须要有上面一行注册过的才能这样用，不然的话就去掉最后一个参数
//UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
//UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
//没有注册需要创建
// if (cell == nil) {
// cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
int row = [indexPath row];
//当有多个view没有继承SecondVIewController的时候,可以这样写
//[((UITableViewController *)self.array[row] valueForKey:@"Title")];
cell.textLabel.text = ((DXWDiscosureButtonViewController *)self.array[row]).title;
cell.imageView.image = ((DXWDiscosureButtonViewController *)self.array[row]).image;
//有右边的 符号
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
// DXWDiscosureButtonViewController *detailViewController = [[DXWDiscosureButtonViewController alloc] init];
//[detailViewController release];
int row = [indexPath row];
[self.navigationController pushViewController:self.array[row] animated:YES];
@end
3.修改Delegate，设置根视图控制器
#import "DXWAppDelegate.h" #import "FirstViewController.h" //导入根视图控制器头文件 @implementation DXWAppDelegate - (void)dealloc [_window release]; [super dealloc]; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; //创建首页 FirstViewController *first = [[FirstViewController alloc] initWithStyle:UITableViewStylePlain]; //创建一个导航栏，其中的首页是FirstViewController UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:first]; //将导航栏作为根视图控制器 self.window.rootViewController = nav; self.window.backgroundColor = [UIColor whiteColor]; [self.window makeKeyAndVisible]; return YES;
4.创建所有子视图的一个基类控制器，命名为SecondViewController SecondViewController.h:
#import UIKit/UIKit.h @interface SecondViewController : UITableViewController @property(nonatomic,retain)UIImage *image; @end
SecondViewController.m:
#import "SecondViewController.h"
@interface SecondViewController ()
@implementation SecondViewController
static NSString *cellRequestIdentifier = @"CellReuseIdentifier";
- (id)initWithStyle:(UITableViewStyle)style
self = [super initWithStyle:style];
if (self) {
//self.title = @"SecondView";
return self;
- (void)viewDidLoad
[super viewDidLoad];
//注册
[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:cellRequestIdentifier];
- (void)didReceiveMemoryWarning
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
#warning Potentially incomplete method implementation.
// Return the number of sections.
return 1;
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
#warning Incomplete method implementation.
// Return the number of rows in the section.
return 1;
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
return cell;
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
5.创建二级子视图控制器，也就是上图所示的水果选项卡的内容控制器，命名为DXWDiscosureButtonController,继承自SecondViewController。
#import "SecondViewController.h" @interface DXWDiscosureButtonViewController : SecondViewController @property(nonatomic,retain) NSMutableArray *array; @end
DXWDiscosureButtonController.m:
#import "DXWDiscosureButtonViewController.h"
#import "ThirdViewController.h"
@interface DXWDiscosureButtonViewController ()
@implementation DXWDiscosureButtonViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.image = [UIImage imageNamed:@"disclosureButtonControllerIcon"];
self.title = @"水果";
return self;
- (void)viewDidLoad
[super viewDidLoad];
self.array = [[NSMutableArray alloc] initWithObjects:@"apple",@"orange",@"pitch",@"lenmon",@"balana", nil];
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
return [self.array count];
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
int row = [indexPath row];
cell.textLabel.text = [self.array objectAtIndex:row];
// cell.imageView.image = ((DXWDiscosureButtonViewController *)self.array[row]).image;
//有右边的 符号
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
return cell;
- (void)didReceiveMemoryWarning
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
-(void)dealloc
[self.array release];
[super dealloc];
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
int row = [indexPath row];
UIAlertView *a = [[UIAlertView alloc] initWithTitle:@"Title" message:[NSString stringWithFormat:@"你选择了%@",self.array[row]] delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
[a show];
//右边的 符号响应事件
-(void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
int row = [indexPath row];
// UIAlertView *a = [[UIAlertView alloc] initWithTitle:@"Title" message:[NSString stringWithFormat:@"你选择了%@",self.array[row]] delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
// [a show];
ThirdViewController *thirdViewController = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil];
thirdViewController.str = self.array[row];
[self.navigationController pushViewController:thirdViewController animated:YES];
[thirdViewController release];
@end
6.创建第三级子视图控制器，也就是点击了某个水果选项卡的最右边的那个绿色按钮，会跳转到第三个视图，并且显示你所点击的水果名字，命名为ThirdViewController,继承自普通的ViewController,并且带有xib文件
#import UIKit/UIKit.h @interface ThirdViewController : UIViewController @property (retain, nonatomic) IBOutlet UILabel *lblshow; @property (nonatomic,copy) NSString *str; @end
ThirdViewController.m:
#import "ThirdViewController.h"
@interface ThirdViewController ()
@implementation ThirdViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = @"ThirdViewController";
return self;
@end
7.创建根视图控制器的第二个选项卡的二级视图控制器，也就是选择的省市选项卡，命名为DXWCheckViewController，继承自tableViewController，不带xib文件
实现的效果是点击某行，这行显示mark
DXWCheckViewController.h:#import "SecondViewController.h" @interface DXWCheckViewController : SecondViewController @property(nonatomic,retain) NSMutableArray *array; @property(nonatomic,assign) int selectedValue; @end
DXWCheckViewController.m:
#import "DXWCheckViewController.h"
@interface DXWCheckViewController ()
@implementation DXWCheckViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.image = [UIImage imageNamed:@"checkmarkControllerIcon.png"];
self.title = @"省市";
return self;
- (void)viewDidLoad
[super viewDidLoad];
self.selectedValue = -1;
self.array = [[NSMutableArray alloc] initWithObjects:@"北京",@"上海",@"重庆",@"天津",@"江苏",@"浙江",@"河北",@"湖南",@"河南",@"湖北", nil];
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
return [self.array count];
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
int row = [indexPath row];
cell.textLabel.text = [self.array objectAtIndex:row];
// cell.imageView.image = ((DXWDiscosureButtonViewController *)self.array[row]).image;
//有右边的 符号
//cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
if (self.selectedValue == row) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
else
cell.accessoryType = UITableViewCellAccessoryNone;
return cell;
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
int row = [indexPath row];
//方法一：简洁明了的方法
//self.selectedValue = row;
//[tableView reloadData];
//方法二：现货的以前的选中的cell,将其accessoryType设为None
NSIndexPath *path = [NSIndexPath indexPathForRow:self.selectedValue inSection:0];
//将轩中行的accessoryType设为Checkmark
UITableViewCell *oldCell = [tableView cellForRowAtIndexPath:path];
oldCell.accessoryType = UITableViewCellAccessoryNone;
//将selectedValue设为当前轩中行
self.selectedValue = row;
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
cell.accessoryType = UITableViewCellAccessoryCheckmark;
-(void)dealloc
[self.array release];
[super dealloc];
- (void)didReceiveMemoryWarning
[super didReceiveMemoryWarning];
@end
8.添加继承自SecondViewController的班级选项卡的二级视图控制器，命名为ButtonViewController
#import "SecondViewController.h" @interface ButtonViewController : SecondViewController @property(retain,nonatomic) NSArray *array; @end
ButtonViewController.m:
[super viewDidLoad]; self.array = [NSArray arrayWithObjects:@"一班",@"二班",@"三班",@"四班",@"五班",@"六班",@"七班",@"八班",@"九班",@"十班",@"十一班",@"十二班",@"十三班",@"十四班",nil]; -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section return [self.array count];
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath static NSString *identifier = @"Identifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier]; UIImage *image = [UIImage imageNamed:@"button_up"];//设置button的背景图片 UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [button setBackgroundImage:image forState:UIControlStateNormal]; //button.frame = CGRectMake(0, 0, 150, 30); [button sizeToFit];//自适应图片的大小 [button setTitle:@"详细信息" forState:UIControlStateNormal]; [button addTarget:self action:@selector(buttonClick:) forControlEvents:UIControlEventTouchUpInside]; cell.accessoryView = button; cell.accessoryView.tag = [indexPath row]; int row = [indexPath row]; cell.textLabel.text = self.array[row]; return cell; -(void)buttonClick:(id)sender //通过button的上一级可以拿到那个cell，在通过cell来拿到它所在的行数，然后可以获得相应的数据 UIButton *button = sender; UITableViewCell *cell = (UITableViewCell *)[button superview]; NSIndexPath *indexpath = [self.tableView indexPathForCell:cell]; int row = [indexpath row]; NSLog(@"%d班",row+1); UIAlertView *a = [[UIAlertView alloc] initWithTitle:@"详细信息" message:[NSString stringWithFormat:@"%d班",row+1] delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [a show];
9.创建可以移动的tableview效果，命名为MoveViewController，继承自SecondViewController，不带xib
操作：点击Edit按钮之后，可以点击每行右边的按钮进行拖动。 MoveViewController.h:
#import "SecondViewController.h" @interface MoveViewController : SecondViewController @property(retain,nonatomic)NSMutableArray *array; @endMoveViewController.m:
#import "MoveViewController.h"
@interface MoveViewController ()
@implementation MoveViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = @"Move";
self.image = [UIImage imageNamed:@"moveMeIcon"];
NSArray *arr = @[@"小明",@"小花",@"小李",@"小王",@"小丁",@"小张",@"小康",@"小刘",@"小墩",@"大墩"];
self.array = [arr mutableCopy];
return self;
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
return [self.array count];
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
static NSString *identifier = @"Identifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
int row = [indexPath row];
cell.textLabel.text = self.array[row];
return cell;
- (void)viewDidLoad
[super viewDidLoad];
//首先要添加右上角的一个edit按钮，按钮按下去可以设置可以编辑
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(itemButtonClick:)];
//[button setTitle:@"move"];
self.navigationItem.rightBarButtonItem = button;
-(void)itemButtonClick:(id)sender
//设置可以编辑
[self.tableView setEditing:!self.tableView.editing];//设置成和当前状态相反的状态
//设置编译图标
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
return UITableViewCellEditingStyleNone;
//设置是否可以移动
-(BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
return YES;
-(void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath
id object= self.array[[sourceIndexPath row]];
[self.array removeObject:self.array[[sourceIndexPath row]]];
[self.array insertObject:object atIndex:[destinationIndexPath row]];
NSLog(@"%d",[self.array count]);
@end
10.创建一个带删除功能的tableViewController,同样继承自SecondViewController，不带xib
#import "SecondViewController.h" @interface DelViewController : SecondViewController @property(retain,nonatomic)NSMutableArray *array; @end
DelViewController.m:
#import "DelViewController.h"
@interface DelViewController ()
@implementation DelViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = @"Delete";
self.image = [UIImage imageNamed:@"deleteMeIcon"];
NSArray *arr = @[@"小明",@"小花",@"小李",@"小王",@"小丁",@"小张",@"小康",@"小刘",@"小墩",@"大墩"];
self.array = [arr mutableCopy];
return self;
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
return [self.array count];
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
static NSString *identifier = @"Identifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
int row = [indexPath row];
cell.textLabel.text = self.array[row];
return cell;
//首先要添加右上角的一个edit按钮，按钮按下去可以设置可以编辑
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(itemButtonClick:)];
//[button setTitle:@"move"];
self.navigationItem.rightBarButtonItem = button;
//设置可以编辑
[self.tableView setEditing:!self.tableView.editing];//设置成和当前状态相反的状态
if (self.tableView.editing) {
[self.navigationItem.rightBarButtonItem setTitle:@"Done"];
else
[self.navigationItem.rightBarButtonItem setTitle:@"Delete"];
//设置编译图标
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
return UITableViewCellEditingStyleDelete;
//将数据从数组和tableview中删掉
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
int row = [indexPath row];
[self.array removeObjectAtIndex:row];
[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationRight];
//可以根据行来设置delete按钮位置上button的标题
-(NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath
return @"我要删你";
@end
11.创建一个继承自SecondViewController，具有添加功能的视图控制器，命名为AddViewController
AddViewController.h:
#import "SecondViewController.h" @interface AddViewController : SecondViewController UIAlertViewDelegate @property(retain,nonatomic)NSMutableArray *array; @property(retain,nonatomic)NSIndexPath *indexPath; @end
AddViewController.m:
#import "AddViewController.h"
@interface AddViewController ()
@implementation AddViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = @"Add";
self.image = [UIImage imageNamed:@"deleteMeIcon"];
NSArray *arr = @[@"小明",@"小花",@"小李",@"小王",@"小丁",@"小张",@"小康",@"小刘",@"小墩",@"大墩"];
self.array = [arr mutableCopy];
return self;
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
return [self.array count];
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
static NSString *identifier = @"Identifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
int row = [indexPath row];
cell.textLabel.text = self.array[row];
return cell;
//首先要添加右上角的一个edit按钮，按钮按下去可以设置可以编辑
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(itemButtonClick:)];
//[button setTitle:@"move"];
self.navigationItem.rightBarButtonItem = button;
//设置可以编辑
[self.tableView setEditing:!self.tableView.editing];//设置成和当前状态相反的状态
if (self.tableView.editing) {
[self.navigationItem.rightBarButtonItem setTitle:@"Done"];
else
[self.navigationItem.rightBarButtonItem setTitle:@"Delete"];
//设置编译图标
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
return UITableViewCellEditingStyleInsert;
//实现UIAlertView代理协议
-(void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
//获取AlertView中的数据
NSString *str = [alertView textFieldAtIndex:0].text;
//将数据插入到array数组中（位置是点击的位置的下一行）
[self.array insertObject:str atIndex:[self.indexPath row]+1];
//用点击位置的下一行创建一个新的NSIndexPath
int newrow = [self.indexPath row]+1;
NSIndexPath *index = [NSIndexPath indexPathForRow:newrow inSection:0];
//在tableView的这个NSIndexPath中插入数据
[self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:index] withRowAnimation: UITableViewRowAnimationFade];
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
//获得点击的indexPath
self.indexPath = indexPath;
//创建一个UIAlertView,用来获得数据
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"enterstring" message:nil delegate:self cancelButtonTitle:@"ok" otherButtonTitles: nil];
//带有输入框的UIAlertView
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];
//添加固定的内容
// [self.array insertObject:@"aaa" atIndex:[indexPath row]];
// int row = [indexPath row];
// [self.array removeObjectAtIndex:row];
// [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationRight];
Person *p = [[Person alloc] init] ; //拷贝函数不需要release,这里用autorelease会报错
p.name = [self.name copy];
p.age = self.age;
return p;
-(NSString *)description
NSLog(@"%@,%d",self.name,self.age);
@end
13.创建继承自SecondViewcontroller的具有修改功能的tableViewController,命名为ChangeViewController，不带xib文件：
#import "SecondViewController.h" #import "Person.h" //申明协议,修改自己页面中的内容 @protocol change NSObject //协议1 //-(void)changeData:(id)controller;//这里也可以是子视图的controller对象,然后想获取对象里面的任何值都可以 //协议2 -(void)changeData:(int)row Per:(Person *)p; @interface ChangeViewController : SecondViewController change @property(retain,nonatomic)NSMutableArray *array; @property(copy,nonatomic)Person *per; //-(void)changeData:(int)row; @end
ChangeViewController.m：
#import "ChangeViewController.h"
#import "EditViewController.h"
@interface ChangeViewController ()
@implementation ChangeViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = @"修改";
self.image = [UIImage imageNamed:@"detailEditIcon"];
self.array = [[NSMutableArray alloc] initWithCapacity:5];
for (int i=0; i i++) {
Person *p = [[Person alloc] init];
p.name = [NSString stringWithFormat:@"xiaoming%d",i];
p.age = 20+i;
[self.array addObject:p];
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
return [self.array count];
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
int row = [indexPath row];
static NSString *identifier = @"Identifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:identifier];
Person *p = self.array[row];
cell.textLabel.text = p.name;
cell.detailTextLabel.text = [NSString stringWithFormat:@"%d",p.age];
return cell;
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
Person *p = self.array[indexPath.row];
NSLog(@"%@,%d",p.name,p.age);
EditViewController *edit = [[EditViewController alloc] init];
edit.per = [p copy];
edit.row = indexPath.row;
edit.delegate = self;
[self.navigationController pushViewController:edit animated:YES];
@end
14.创建可以保存修改值的三级子试图控制器，带有xib
#import UIKit/UIKit.h #import "Person.h" #import "ChangeViewController.h" @interface EditViewController : UIViewController @property(copy,nonatomic)Person *per;//对象 @property (retain, nonatomic) IBOutlet UITextField *name; @property (retain, nonatomic) IBOutlet UITextField *age; @property(assign,nonatomic) int row; //位置 @property(nonatomic,retain)id change delegate; @end
EditViewController.m:
#import "EditViewController.h"
@interface EditViewController ()
@implementation EditViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = @"信息修改";
return self;
-(void)viewWillAppear:(BOOL)animated
self.name.text = self.per.name;
self.age.text = [NSString stringWithFormat:@"%d",self.per.age];
- (void)viewDidLoad
[super viewDidLoad];
//首先要添加右上角的一个edit按钮，按钮按下去可以设置可以编辑
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithTitle:@"返回" style:UIBarButtonItemStyleBordered target:self action:@selector(itemLeftButtonClick:)];
self.navigationItem.leftBarButtonItem = button;
UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithTitle:@"保存" style:UIBarButtonItemStyleBordered target:self action:@selector(itemRightButtonClick:)];
self.navigationItem.rightBarButtonItem = button1;
-(void)itemLeftButtonClick:(id)sender
[self.navigationController popViewControllerAnimated:YES];
-(void)itemRightButtonClick:(id)sender
[self changedata];
[self.navigationController popViewControllerAnimated:YES];
self.per.age = [self.age.text intValue];
if ([self.delegate respondsToSelector:@selector(changeData:Per:)]) {
[self.delegate changeData:self.row Per:self.per];
- (void)dealloc {
[_name release];
[_age release];
[super dealloc];

iOS小技能：应用外导航 1. 应用外导航：是指以URL跳转的方式(在iOS中就是以URL Scheme的方式)，直接跳到对应的地图APP中，直接利用对方的功能来导航。这样的优点，一是接入方便，二是不增加自己APP的开销。 2. 应用内导航：是指使用地图服务提供的SDK(如高德,百度)，直接将导航功能嵌入到我们自己的APP内部。 需求：跳转到已经安装的地图 背景：为了减少app内存开支，以URI跳转的方式直接跳转到对应的地图进行导航，让最专业的人做最专业的事。
