Question

我正在添加一个NavigationController作为我主视图的子视图，带有翻转动画（就像实用程序app / flipview一样）。

以下是我的表现：

[UIView beginAnimations:nil context:NULL];
 [UIView setAnimationDuration:.7];
 [UIView setAnimationTransition:([self.tableController.view superview] ? UIViewAnimationTransitionFlipFromLeft : UIViewAnimationTransitionFlipFromRight) forView:self.tableHostView cache:YES];



  [self.tableController.view removeFromSuperview];

  settingsView* backView1 = [[settingsView alloc] initWithNibName:@"settingsView" bundle:nil];
  backView1.delegate = self;
  UINavigationController* settingsNavStack = [[UINavigationController alloc]initWithRootViewController:backView1];
  [backView1 release];

  settingsNavStack.view.frame = CGRectMake(0, 0, 320, 460);
  settingsNavStack.navigationItem.title = @"Settings";

  [self setBackView:settingsNavStack];

  [settingsNavStack release];

  [self.tableHostView addSubview:self.backView.view];
  [[self backView]setDelegate: self];

当它加载时，视图非常好。但是，导航栏会保持白色，直到动画结束后的.2秒。

任何人都知道为什么导航栏不会立即显示？

关闭了chaching，使它看起来好一点。但它仍有问题......

当我将它添加到superview时，UINavigationController会闪烁白色
