I think this is a better solution than having a width constraint that you have to modify:

Resize a UITextField while typing (by using Autolayout)

- (IBAction) textFieldDidChange: (UITextField*) textField
{
    [UIView animateWithDuration:0.1 animations:^{
        [textField invalidateIntrinsicContentSize];
    }];
}

You can omit the animation if desired..
