Question

我想在视图控制器中使用转换幻灯片切换视图。我在网上找到了以下代码。

//  get  the  view  that's  currently  showing 
UIView *currentView = self.view; 
//  get  the  the  underlying  UIWindow,  or  the  view  containing  the  current  view  view 
UIView *theWindow = [currentView superview]; 

//  remove  the  current  view  and  replace  with  myView1 
[currentView removeFromSuperview]; 
[theWindow  addSubview:PlayingView]; 
PlayingView.frame = CGRectMake(0, 0, 320, 460);
//  set  up  an  animation  for  the  transition  between  the  views 
CATransition *animation = [CATransition animation]; 
[animation setDuration:1]; 
[animation setType:kCATransitionPush]; 
[animation setSubtype:kCATransitionFromLeft]; 
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];

[[theWindow layer] addAnimation:animation forKey:@"SwitchToView1"];

这段代码很棒，但底部有一个非常讨厌的白色条带！我找到了代码：

  PlayingView.frame = CGRectMake(0, 0, 320, 460);

似乎不起作用。

Answer 1

它需要480高，而不是460，但您应该使用PlayingView.frame = theWindow.bounds而不是手动创建CGRect。它也适用于通用应用程序或景观。

Answer 2

如果您没有显示状态栏，则屏幕高度为480（状态栏为20像素）。所以尝试将其更改为CGRectMake（0,0,320,480）。
