为什么UIActionSheet不支持我的景观？

Question

我有一个带有tabbarcontroller的应用程序，两个带有它的controller，现在在一个controller中我以肖像模型显示了uiactionsheet：

UIActionSheet*ActionSheet=[[UIActionSheet alloc]InitWithTitle:@＂＂Delegate:nil CancelButtonTitle:@＂Cancel＂DestructiveButtonTitle:@＂Del＂OtherButtonTitles：nil,nil]；

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

如果操作表没有显示，控制器可以改变景观，为什么？非常感谢！！！

试试看：

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];
  }
