iPad上的屏幕高度

我对iPad上的UIActionsheet有一些问题 他的身高并没有随着变化而变化，所以我看不到“完成”按钮

这是我的代码：

-(void) showActionSheet{

UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"" 
                                                  delegate:self
                                         cancelButtonTitle:@"cancel"
                                    destructiveButtonTitle:@"Done"
                                         otherButtonTitles:nil];

Reports = [[NSMutableArray alloc] init];
    //Add the picker
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
    datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 80, 0, 0)];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(5, 20, 400, 420)];
datePicker.datePickerMode = UIDatePickerModeDate;
[menu addSubview:datePicker];
[menu showFromRect:[self frame] inView:self animated:YES];        
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
    [menu setBounds:CGRectMake(0,0,480, 260)];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    [menu setBounds:CGRectMake(-20,10,480, 400)];
menu.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleTopMargin
|UIViewAutoresizingFlexibleRightMargin|UIViewAutoresizingFlexibleLeftMargin|UIViewAutoresizingFlexibleBottomMargin;
[menu release];


}

要查看完成按钮，您可以像我一样做一件事

UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"" 
                                              delegate:self
                                     cancelButtonTitle:@"cancel"
                                     destructiveButtonTitle:@""
                                     otherButtonTitles:@"",@"",@"Done",nil,nil];

我想这会管用的

我知道这不是一个好方法，但您现在可以这样做。

另一种方法是UIActionSheet*菜单=[[UIActionSheet alloc]initWithTitle:@\n\n\n委托：自取消按钮：@cancel Destructive按钮：@Done OtherButtontiles:nil]；
