Question

我正在使用Vserv完整的sdk进行addintegeration。我正在调用我的adViewController来显示我的add.if失败的添加失败我从addViewController接受SplashViewController.But我收到此警告
Warning: Attempt to present <SplashViewController: 0x1dd697b0> on <AdViewController: 0x1dd68690> whose view is not in the window hierarchy!并且无法导航到我的下一个视图SplashViewController ..我尝试过以下所有方法都是代码。你们可以帮我解决一下：

AdViewController.m

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

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

-(void)viewDidAppear:(BOOL)animated{
    [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;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
        return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
    }
    else {
        return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
    }
}

- (void)adReceivedNotification:(VservAdView*)vservAd{
    NSLog(@"adReceivedNotification");
}

- (void)adFailedNotification:(VservAdView*)vservAd{
    NSLog(@"adFailedNotification");
    appDelegate.window.rootViewController = appDelegate.splashViewController;
    [self presentViewController:appDelegate.splashViewController animated:NO completion:Nil];

}

如果将窗口的根视图设置为splashViewController，为什么要在self上显示视图？

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

改为使用此

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

警告：尝试呈现其窗口层次结构中不存在其视图的ViewController
