Presenting action sheet clipped by its superview

Presenting action sheet clipped by its superview.Some controls might not respond to touches.On iPhone try-[UIActionSheet showFromTabBar:]or-[UIActionSheet showFromToolbar:] instead of -[UIActionSheet showInView:].

今天学UIActionSheet的时候，调试的时候，突然显示这个警告，在stackoverflow上找到这个答案：​​http://stackoverflow.com/questions/4447563/last-button-of-actionsheet-does-not-get-clicked​​

在模拟器里面测试的时候，发现最下面一个按钮点击的时候，不是很好点击了，而且也出现了一大堆警告，这个博客上写出了答案： ​​http://dale.leepood.com/2012/04/​​；

我的代码是这样写的：

UIBarButtonItem*setStyleButton=[[UIBarButtonItemalloc]initWithTitle:@"Style" 
 
   
  
                                                                     style:UIBarButtonItemStyleBorderedtarget:self 
 
   
  
                                                                    action:@selector(setNavigationControllerStyle:)];
 
-(void)setNavigationControllerStyle:(id)sender
 
   
  
{
 
   
  
  //more code
    //[styleAlert showInView:self.view];
 
   
  
    [styleAlert showInView:[UIApplicationsharedApplication].keyWindow];
[styleAlert release];
 
   
  
}
 将代码：
  [styleAlert showInView:self.view]; 改为：
  [styleAlert 
  showInView
  :[
  UIApplication
  sharedApplication
  ].
  keyWindow
  ];即可
