Can I remove iPad Keyboard 'hide keyboard' button?

Looking at the iPad's UIKeyboard I'm noticing a 'hide keyboard' button in the bottom right, w开发者_如何学Pythonhich I would very much like to get rid of. Is this allowed and possible? I'm not sure of the proper name for the button so google isn't helping me a great deal.

Many thanks

You can't remove the "hide keyboard" button from the iPad standard keyboard, it's not permitted by Apple.

However, there is one way you can determine when the "hide keyboard" button is pressed:

- (void)textFieldDidEndEditing:(UITextField *)textField
{
    [textField resignFirstResponder];
}
