Question

在我的应用的iPhone版本中，UIDatePicker中有一个UIActionSheet。看来是对的。我现在正在设置应用程序的iPad版本，在iPad上查看时，UIActionSheet显示为空白框。

以下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;

我最终为iPad Popover创建了一段单独的代码：

//build our custom popover view
UIViewController* popoverContent = [[UIViewController alloc] init];
UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 344)];
popoverView.backgroundColor = [UIColor whiteColor];

datePicker.frame = CGRectMake(0, 44, 320, 300);

[popoverView addSubview:toolbar];
[popoverView addSubview:datePicker];
popoverContent.view = popoverView;

//resize the popover view shown
//in the current view to the view's size
popoverContent.contentSizeForViewInPopover = CGSizeMake(320, 244);

//create a popover controller
UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];

//present the popover view non-modal with a
//refrence to the button pressed within the current view
[popoverController presentPopoverFromBarButtonItem:self.navigationItem.leftBarButtonItem 
                          permittedArrowDirections:UIPopoverArrowDirectionAny 
                                          animated:YES];

//release the popover content
[popoverView release];
[popoverContent release];
