How to customize the UIKeyboard in my app?

I want to change the Return button to Go b开发者_StackOverflow社区utton. Any suggestions??

Thanks,

 *yourtextfieldname*.returnKeyType=UIReturnKeyGo;

UITextField and UITextView both follow the UITextInputTraits protocol, which defines a returnKeyType property. Set that to UIReturnKeyGo and you're good to, er, go.
