我正在尝试使用UIButton获取UIDatePicker以显示在UIActionSheet中.不幸的是,它被裁掉了,整个日期选择器都不可见.我还没有尝试过添加UIButton.任何人都可以建议让整个视图适合吗？我不确定如何添加适当的尺寸,因为UIActionSheet似乎缺少-initWithFrame:类型构造函数.

UIActionSheet *menu = [[UIActionSheet alloc] initWithTitle:@"Date Picker" 
                                                  delegate:self
                                         cancelButtonTitle:@"Cancel"
                                    destructiveButtonTitle:nil
                                         otherButtonTitles:nil];

// Add the picker
UIDatePicker *pickerView = [[UIDatePicker alloc] init];
pickerView.datePickerMode = UIDatePickerModeDate;
[menu addSubview:pickerView];
[menu showInView:self.view];

[pickerView release];
[menu release];

我也尝试过类似的东西:

UIActionSheet *menu = [[UIActionSheet alloc] initWithFrame:CGRectMake(200.0, 200.0, 100.0f, 100.0f)];

这些坐标是不现实的,但它们似乎不会影响UIActionSheet的位置/大小.
