Question

我正在尝试删除我创建的facebook视图控制器。基本上，初始化视图控制器的showFBLoginView方法是App Delegate，并在GameOver层中调用。

-(void)showFBLoginView {

   facebookViewController = [[FacebookViewController alloc] init];
   self.facebookViewController = facebookViewController;

   // Set loginUIViewController as root view controller
   [[self window] setRootViewController:facebookViewController];

   self.window.backgroundColor = [UIColor whiteColor];
   [self.window makeKeyAndVisible];

   [self.facebookViewController activateButton:@"Facebook Connect"];
         .
         .
         .
   }

facebookViewController.m类中的activateButton方法：

-(void)activateButton:(NSString*)buttonText {    
CGSize screenSize = [[CCDirector sharedDirector] winSize];

fbConnectButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
fbConnectButton.frame = CGRectMake(screenSize.width/2 - 50*(screenSize.width/480) , screenSize.height/2, screenSize.width/4, screenSize.height/12);
[fbConnectButton setTitle:buttonText forState:UIControlStateNormal];
fbConnectButton.backgroundColor = [UIColor redColor];
[fbConnectButton setTitleColor:[UIColor brownColor] forState:UIControlStateNormal ];

[fbConnectButton addTarget:self action:@selector(callButtonTouched) forControlEvents:UIControlEventTouchUpInside];

[self.view addSubview:fbConnectButton];

}

我尝试以下列方式删除faceboookViewController。这是在App Delegate中完成的。

  [[self window] removeFromSuperview];

但它不起作用。删除视图控制器的正确方法是什么？

Answer 1

 faceboookViewController *fbViewController =
[self.storyboard instantiateViewControllerWithIdentifier:@"StoryboardID"];
[self dismissViewControllerAnimated:YES completion:nil];

StoryboardID是faceboookViewController的StoryboardID。如果你出示，你可以解雇。
