为什么UIActionSheet不支持我的风景？

Question

我有一个带有tabbarcontroller的应用程序，带有两个控制器，现在在一个控制器中我在肖像模型中显示了一个uiactionsheet：

UIActionSheet * actionSheet = [[UIActionSheet alloc]                    initWithTitle：@ “”                    delegate：nil cancelButtonTitle：@“取消”                                   destructiveButtonTitle：@ “删除”                    otherButtonTitles：无，无];

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，因为它不响应控制器委托：

- （void）willRotateToInterfaceOrientation：（UIInterfaceOrientation）toInterfaceOrientation duration：（NSTimeInterval）duration

如果动作表没有显示，控制器可以改变景观，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];
  }
