问题
Is it possible to display keyboard consisting of only numbers from 0-9 in iPad?, i don't want the keyboard to display anything else. I know there is this KeyboardType:Number Pad that we can in the .xib file, but it displays all other extra characters including numbers. I want to use this concept in displaying keyboard for PIN login for my iPad application that I'm working on. Thank you

You need to implement your own keyboard if you want this on iPad.
There are many examples out there:

You may be looking for: UIKeyboardTypeDecimalPad which will display numbers and a decimal point.
