在UINavigationController中，按钮无法与pushViewController一起使用

Question

我想制作一个简单的导航控制应用程序，其中有两个视图控制器（ViewController和ViewController2）。我在ViewController中有一个按钮，当我按下按钮时，我想让它进入另一个视图。问题是该按钮不起作用。我也尝试过UIViewController，但是也没有这样做。

的AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
    { 
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 
    // Override point for customization after application launch. 

    ViewController *vc1 = [[ViewController alloc]init]; 

    UINavigationController *nav=[[UINavigationController alloc]initWithRootViewController:vc1]; 

    self.window.rootViewController = nav; 


    [self.window makeKeyAndVisible]; 
    [self.window addSubview:nav.view]; 
    return YES; 
} 

的ViewController.m

- (IBAction)myButton:(id)sender { 

    ViewController *vc2 = [[ViewController alloc]init]; 

    [[self navigationController]pushViewController:vc2 animated:YES]; 
} 

在此先感谢您的帮助

，如果你使用你的ViewController1的ViewController2故事板的进口，给故事板ID为“view2”：

ViewController2 *vc2 = (ViewController2 *)[self.storyboard instatiateViewControllerWithIdentifier:@"view2"]; 
    [self.navigationController pushViewController:vc2 animated:YES];
