Question

I implemented the UIDatePicker in iPhone and it’s working correctly.

The same code I tried with iPad but it is not showing me UIDatePicker.

I read somewhere that I need to show it with UIPopOverController and find this
link but it is not showing the proper code.

I can’t make a separate XIB for that. I have to implement it by code itself.
Mine is IOS5.

I use the following code:

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
    if (textField.tag == 1)
    {
            [self showDatePickerIniPad];
      }
}
   -(void)showDatePickerIniPad
 {
     UIViewController *popoverContent = [[UIViewController alloc] init];
     UIView *popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
     popoverView.backgroundColor = [UIColor whiteColor];
     datePicker.frame = CGRectMake(0, 0, 320, 300);
     [popoverView addSubview:datePicker];
     popoverContent.view = popoverView;
     popoverContent.contentSizeForViewInPopover = CGSizeMake(320, 244);

     UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
     [popoverController presentPopoverFromRect:CGRectZero inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];

     txt_FromDate.inputView = datePicker;
 }
