How to move UP the UIVIEW when keyboard is display or typing in UITEXTFIELD in IOS !!!

In my recent project i have faced a small problem when i have to provide data through UITEXTFIELD , but the problem is that after 4 UITEXTFIELD rest of the UITEXTFIELD’s are hide behind the keyboards, so the simple solution is to solve this issue is to keep your UITEXTFIELD scroll to UP/Down.

You will need a scroll view if the contents you have now does not fit in the iPhone screen.
