One common problem that you face while UIPickerView’s using is, although the width is changeable but height is not re-sizable.

At this point you have two ways to fix this problem

• Create custom UI picker
• Use UIScrollView

Developing the custom UI picker is an overkill. Using UIScrollView is much easier and simpler solution.
This is how you can do it:

• Put a UIScrollView control.
• Move your UIPickerView inside this UIScrollView
• Adjust height of UIScrollView as per your requirements
