警告：試圖提出ViewController中，其觀點是不存在於窗口層次

Question

我使用Vserv完整的SDK addintegeration.I'm打電話給我adViewController提出我add.if失敗添加失敗，我要帶去臺灣的SplashViewController從我的addViewController.But我得到這個警告
Warning: Attempt to present <SplashViewController: 0x1dd697b0> on <AdViewController: 0x1dd68690> whose view is not in the window hierarchy!，無法導航到我的下一個視圖是SplashViewController ..我試過以下所有的方法是code.Could你們幫我：

AdViewController.m

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    appDelegate = (AppDelegate*)[[UIApplication sharedApplication] delegate]; 

    // Do any additional setup after loading the view from its nib. 
}

    [super viewDidAppear:animated]; 
    if([Util isInternetAvailable]) 
    { 
     //Initializes SDK 
     [VservAdManager initializeSDK]; 

     CGRect frame1; 

     if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) 
      frame1 = CGRectMake(0,0,1024,768); 

     else 
      frame1 = CGRectMake(0,0,320,480); 

     vservAdView = [[VservAdView alloc] initWithFrame:frame1]; 

     [vservAdView requestAd:self:@"7825":nil]; 

     [self.view addSubview: vservAdView]; 
    } 
    else{ 

     appDelegate = (AppDelegate *) [[UIApplication sharedApplication] delegate]; 
     appDelegate.window.rootViewController = appDelegate.splashViewController; 
     [self presentModalViewController:appDelegate.splashViewController animated:NO]; 
    } 
} 

- (void)viewDidUnload

    [super viewDidUnload]; 
    // Release any retained subviews of the main view. 
    // e.g. self.myOutlet = nil; 
}

    } 
}

你爲什麼要提出看法自我，如果你設置窗口的根視圖splashViewController？

appDelegate = (AppDelegate *) [[UIApplication sharedApplication] delegate]; 
appDelegate.window.rootViewController = appDelegate.splashViewController; 
[self presentModalViewController:appDelegate.splashViewController animated:NO]; 

如果讀音字評論的第二行，而不是使用該

appDelegate = (AppDelegate *) [[UIApplication sharedApplication] delegate]; 
//appDelegate.window.rootViewController = appDelegate.splashViewController; 
[appDelegate.window presentModalViewController:appDelegate.splashViewController animated:NO];
