UINavigationController与UITabBarController相关问题

UINavigationController与UITabBarController相关问题

UINavigationController与UITabBarController混用是非常常见的,有时候会遇到UINavigationController推出(push)出controller后隐藏UITabBarController的问题,很容易对吧.

源码如下:

//

// AppDelegate.m

// NavigationController

// Copyright (c) 2014年 Y.X. All rights reserved.

#import "AppDelegate.h"

#import "RootViewController.h"

#define CreateNavigationControllerWith(controller) \

[[UINavigationController alloc] initWithRootViewController:controller]

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

 self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

 // 初始化导航栏控制器

 UINavigationController *newProductNC = \

 CreateNavigationControllerWith([RootViewController new]);

 // 初始化TabBarController

 UITabBarController *rootBC = [[UITabBarController alloc] init];

 rootBC.viewControllers = @[newProductNC];

 // 交给系统管理

 self.window.rootViewController = rootBC;

 self.window.backgroundColor = [UIColor whiteColor];

 [self.window makeKeyAndVisible];

 return YES;

@end

//

// RootViewController.m

// NavigationController

// Copyright (c) 2014年 Y.X. All rights reserved.

#import "RootViewController.h"

#import "SecondViewController.h"

@interface RootViewController ()

@implementation RootViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

 self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

 if (self)

 self.title = @"YouXianMing";

 return self;

- (void)viewDidLoad

 [super viewDidLoad];

 // 设定背景色

 self.view.backgroundColor = [UIColor whiteColor];

 // 点击手势

 UITapGestureRecognizer *tapGesture = \

 [[UITapGestureRecognizer alloc] initWithTarget:self

 action:@selector(tapEvent:)];

 // 添加手势

 [self.view addGestureRecognizer:tapGesture];

- (void)tapEvent:(UIGestureRecognizer *)sender

 [self.navigationController pushViewController:[SecondViewController new]

 animated:YES];

@end

//

// SecondViewController.m

// NavigationController

// Copyright (c) 2014年 Y.X. All rights reserved.

#import "SecondViewController.h"

@interface SecondViewController ()

@implementation SecondViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

 self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

 if (self)

 return self;

- (void)viewDidLoad

 [super viewDidLoad];

 self.view.backgroundColor = [UIColor whiteColor];

@end

效果:

将RootViewController.m中tapEvent:修改一下,如下所示:

效果(注意看底部的隐藏效果哦):

注意:隐藏与取消隐藏是成对出现的.
