Question

I have a UIDatePicker in count down timer mode . UIDatePicker by default is not supporting auto resizing. So I manually set the frame to resize for the landscape orientation

- (void) resizeDatePicker: (UIInterfaceOrientation)orientation
 {
    if (UIInterfaceOrientationIsPortrait(orientation)) 
      {
    self.timePicker.frame = CGRectMake(0, 44, 320, 216);
      }
    else 
     {
    self.timePicker.frame = CGRectMake(0, 44, 480, 162);
     }
  }

Its works in all other modes except for count down timer. In count down mode it’s not appearing clearly.

Answer 1

Solved my problem.. Iam posting my answer here.. may help others. In count down timer mode you cannot resize the frame directly. So I added the date picker as subview of a view then apply CGAffineTransformMakeScale to the view. Then I set the frame to appropriate position also.

if (UIInterfaceOrientationIsPortrait(orientation)) 
{

    self.pickerView.transform = CGAffineTransformIdentity;
    self.pickerView.frame =CGRectMake(0,40, 320, 216);

}
else 
{

    self.pickerView.transform = CGAffineTransformMakeScale(0.65, 0.65);
    self.pickerView.frame =CGRectMake(0,40, 480, 140);

}

It will reduce the size of the picker by 65%. PickerView is the view contains the picker.
