在我的应用程序的iPhone版本中,我有UIDatePicker一个UIActionSheet.看来是对的.我现在正在设置应用程序的iPad版本,UIActionSheet在iPad上查看时显示为空白空白框.

这是我正在使用的代码:

UIDatePicker *datePickerView = [[UIDatePicker alloc] init];
    datePickerView.datePickerMode = UIDatePickerModeDate;

    self.dateActionSheet = [[UIActionSheet alloc] initWithTitle:@"Choose a Follow-up Date"
                                                   delegate:self cancelButtonTitle:nil 
                                     destructiveButtonTitle:nil otherButtonTitles:@"Done", nil];

    [self.dateActionSheet showInView:self.view];
    [self.dateActionSheet addSubview:datePickerView];
    [self.dateActionSheet sendSubviewToBack:datePickerView];
    [self.dateActionSheet setBounds:CGRectMake(0,0,320, 500)];

    CGRect pickerRect = datePickerView.bounds;
    pickerRect.origin.y = -95;
    datePickerView.bounds = pickerRect;
