how can I show only number format input in UITextField?

Question

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 UITextField?

If you are not getting my question, you may ask anything again I do appreciate if I will get proper way of doing this,

If you want your text field to accept only the numbers, you can set it's keyboardType property to UIKeyboardTypeNumberPad.

[yourTextField setKeyboardType:UIKeyboardTypeNumberPad];

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

but one issue is that how can UIKeyboardTypeNumberPad will dismiss when I finish typing in it ? – Chatar Veer Suthar Feb 08 '11 at 06:53
Are you implementing `UITextFieldDelegate` methods? If so, in the `textFieldShouldReturn:` method, add the line `[yourTextField resignFirstResponder]`. It will automatically dismiss the keyboard. – EmptyStack Feb 08 '11 at 06:54
@Simon, yes, but when the format is UIKeyboardTypeNumberPad then there is no return or DONE key, I can dismiss normal keyboard which is using for input of hotel name, but for price keyboard(UIKeyboardTypeNumberPad) I can't, help me out – Chatar Veer Suthar Feb 08 '11 at 07:02
Yes.. Sorry for my comment regarding dismissing number pad.. I haven't tried dismissing it before. But the following post has a solution for this.. http://stackoverflow.com/questions/584538/how-to-show-button-done-on-number-pad-on-iphone.. – EmptyStack Feb 08 '11 at 07:09

This could be done in the Interface Builder as well:
