增加UITextFieldDelegate委托

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    // When the user presses return, take focus away from the text field so that the keyboard is dismissed.
    NSTimeInterval animationDuration = 0.30f;
    [UIView beginAnimations:@"ResizeForKeyboard" context:nil];
    [UIView setAnimationDuration:animationDuration];
    CGRect rect = CGRectMake(0.0f, 0.0f, self.view.frame.size.width, self.view.frame.size.height);
    self.view.frame = rect;
    [UIView commitAnimations];
    [textField resignFirstResponder];
    return YES;
}

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
        CGRect frame = textField.frame;
        int offset = frame.origin.y + 32 - (self.view.frame.size.height - 216.0);//键盘高度216
        NSTimeInterval animationDuration = 0.30f;
        [UIView beginAnimations:@"ResizeForKeyBoard" context:nil];
        [UIView setAnimationDuration:animationDuration];
        float width = self.view.frame.size.width;
        float height = self.view.frame.size.height;
        if(offset > 0)
        {
                CGRect rect = CGRectMake(0.0f, -offset,width,height);
                self.view.frame = rect;
        }
        [UIView commitAnimations];
}
