为什么 UIActionSheet 不支持我的风景？

Question

我有一个带有 tabbarcontroller 的应用程序，有两个控制器，现在在一个控制器中我以纵向模型显示 uiactionsheet：

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"" 委托：无取消按钮标题：@“取消” 破坏性按钮标题：@“Del” otherButtonTitles:nil,nil];

actionSheet.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
[actionSheet showInView:self.view];
actionSheet.autoresizingMask = UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleBottomMargin;
[actionSheet release];

我发现当我将模式更改为横向时，它不起作用，因为它没有响应控制器委托：

-(void) willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation 持续时间:(NSTimeInterval)duration

如果 actionsheet 不显示，控制器可以更改为 Landscape，为什么？非常感谢！！！

试试这个：

UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"Some text..."
                           delegate:self
                  cancelButtonTitle:@"Cancel"
             destructiveButtonTitle:@"Delete"
                  otherButtonTitles:@"Button 1",@"Button 2",nil];

  if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.0 ||
      UIDeviceOrientationIsPortrait([[UIDevice currentDevice] orientation])) {
    [sheet showInView:self.view];
  } else {
    [sheet showInView:self.view.window];
  }
