旋轉：我收到錯誤「wait_fences：無法接收回復：10004003」

Question

我發現了一些類似的問題在stackoverflow，但他們不能解決我的問題。第一次旋轉時，我收到錯誤「wait_fences：無法接收回復：10004003」，它將被阻止一兩秒鐘以在新的方向上打印新的視圖，我的代碼如下：

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration: (NSTimeInterval)duration 
{ 
    if (isLandScape) { 
     [self toHorizontalBrowserView]; 
    } else { 
     [self toVerticalBrowserView]; 
    } 
} 

- (void)toHorizontalBrowserView 
{ 
    [horizontalBrowserViewController viewWillAppear:YES]; 
    [self.activeViewController viewWillDisappear:YES]; 
    [self.activeViewController.view removeFromSuperview]; 
    [_viewController.centerView insertSubview: horizontalBrowserViewController.view atIndex:0]; 
    [self.activeViewController viewDidDisappear:YES]; 
    [horizontalBrowserViewController viewDidAppear:YES]; 
    self.activeViewController = horizontalBrowserViewController; 
} 

- (void)toVerticalBrowserView 
{  
    [verticalPhotoBrowserViewController viewWillAppear:YES]; 
    [self.activeViewController viewWillDisappear:YES]; 
    [self.activeViewController.view removeFromSuperview]; 
    [_viewController.centerView insertSubview:verticalPhotoBrowserViewController.view atIndex:0]; 
    [self.activeViewController viewDidDisappear:YES]; 
    [verticalPhotoBrowserViewController viewDidAppear:YES]; 
    _activeViewController = verticalPhotoBrowserViewController; 
} 

這個問題的原因是什麼？如何解決它？

我以前有過這個問題。我認爲問題在於，您正在更新/更改視圖堆棧，同時它將呈現動畫效果。嘗試註釋掉要刪除的位並插入子視圖。
