how can I show only number format input in UITextField?

I am making simple application that will take hotel name and price of item, and I want to show the price in only number format, because it can not be in alphabatical format, so what should I do add in code so that only number will be inputted in the Price UITextFiel开发者_StackOverflow社区d?

There are different types of keyboardTypes available, which you can refer in UITextInputTraits Protocol Reference.

This could be done in the Interface Builder as well:
