What is a good practice to adjust/moving view up and down when keyboard is shown, without using a scroll view(iOS)?

Question

What is a good practice/way to adjust/moving view up and down when keyboard is shown, without using a scroll view?

I've posted this because my method was not working properly, and I desperately need a method that is safe and works.

Answer 1

Have you tried as like below?

- (void)viewDidLoad
{
    NSNotificationCenter * center = [NSNotificationCenter defaultCenter];

    [center addObserver:self selector:@selector(keyboardDidAppear) name:UIKeyboardDidShowNotification object:nil];

    [center addObserver:self selector:@selector(keyboardWillDisAppear) name:UIKeyboardWillHideNotification object:nil];

}

-(void)keyboardDidAppear
{
    CGRect frame = view.frame;

    frame.origin.y -= 214.0;

    view.frame = frame;
}

-(void)keyboardWillDisAppear
{
    CGRect frame = view.frame;

    frame.origin.y += 214.0;

    view.frame = frame;
}
