iphone - 为什么 UIActionSheet 不支持我的横向？

Question

我有一个带有 tabbarcontroller 的应用程序，有两个 Controller ，现在在一个 Controller 中，我在纵向模型中显示了一个 uiactionsheet:

UIActionSheet *actionSheet = [[UIActionSheet 分配] 初始化标题:@“” 委托(delegate):无 cancelButtonTitle:@“取消” destructiveButtonTitle:@"删除" 其他按钮标题: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 Controller 委托(delegate):

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

如果操作表不显示， Controller 可以更改为横向，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];
  }
