如何在UIDatePicker iphone中只显示时间

Question

在我的应用程序中,我UIDateTimePicker通过代码显示操作表.它工作正常.但我不想显示日期和日期.如何做到这一点.请帮忙.提前致谢.

码:

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:NSLocalizedString(@"Select     Date",@"Selecte Date")delegate:self cancelButtonTitle:NSLocalizedString(@"Done",@"Done")
destructiveButtonTitle:NSLocalizedString(@"Cancel",@"Cancel")
otherButtonTitles:nil];  


    actionSheet.actionSheetStyle = UIActionSheetStyleBlackTranslucent;
  UIDatePicker  *datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 50, 320, 270)];
    //datePicker.showsSelectionIndicator = YES;
//   datePicker.dataSource = self;
//datePicker.delegate = self;
    [actionSheet addSubview:datePicker];
    [datePicker release];

    [actionSheet showInView:self.view];
    [actionSheet setBounds:CGRectMake(0, 0, 320, 500)];
  [actionSheet release];

Answer 1

datePicker.datePickerMode = UIDatePickerModeTime;

Answer 2

将该datePickerMode属性设置为以下之一:

typedef enum {
   UIDatePickerModeTime,
   UIDatePickerModeDate,
   UIDatePickerModeDateAndTime,
   UIDatePickerModeCountDownTimer
} UIDatePickerMode;
