iOS应用打开AppStore页面

【1】应用内跳转到App Store页

使用官方 StoreKit.framework 框架

#import <StoreKit/StoreKit.h>

- (void)OnButtonClick {
        NSDictionary *dict = [NSDictionary dictionaryWithObject:@"440948110" forKey:SKStoreProductParameterITunesItemIdentifier];
        SKStoreProductViewController *ctrl = [[SKStoreProductViewController alloc] init];
        ctrl.delegate = self;
        [ctrl loadProductWithParameters:dict completionBlock:^(BOOL result, NSError * _Nullable error) {
            if(error) {
                NSLog(@"Error：%@",error.userInfo);
            }
            else {
                [self presentViewController:ctrl animated:YES completion:nil];
            }
        }];
}


#pragma mark - SKStoreProductViewControllerDelegate

- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController {
    [viewController dismissViewControllerAnimated:YES completion:^{
        NSLog(@"productViewControllerDidFinish");
    }];
}

【2】跳转到App Store应用的URL

NSString *urlstr = @"https://itunes.apple.com/app/apple-store/id440948110?mt=8";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlstr]];
