how to restrict UItext field as a numric in ios ?
It allow me all the type of keyboard but I want to restrict it for phone number.
You can set the keyboard type for the textField directly from the interface builder as shown in screenshot. You can use UIKeyboardTypePhonePad or UIKeyboardTypeNumberPad as per your need.
Also you can use this code :
[textField setKeyboardType:UIKeyboardTypePhonePad];

How to detect Keyboard key pressed in iphone?

I am writing an iOS app, and I want to intercept the key which has been pressed and send the character to another part of the program, as well or instead of to the associated text field. Is there a way to do this?
Yes. The delegate method textField:shouldChangeCharactersInRange:replacementString: lets you do what ever you like before the value is added to the text of the text field. You can even decide not to set it on the text field or set some completely different text.
