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:[UIApplicationsharedApplication].keyWindow];即可
