Question

I have an application where I’m moving my entire UIView up when using the keyboard, in order to not hide some important UITextFields.

My problem is that the UITableView that I have there does not behave the same way as all the other views. Instead of moving the entire UITableView, it moves only its top edge, and that resizes the UITableView which is not the desired effect.

My problem is better described here: http://www.youtube.com/watch?v=AVJVMiBULEQ

This is the code that I’m using for the animation:

-(void)setViewMovedUp:(BOOL)movedUp
{
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5]; // if you want to slide up the view
    [UIView setAnimationBeginsFromCurrentState:YES];

    CGRect rect = self.view.frame;

    if (movedUp) {
        // 1. move the view's origin up so that the text field that will be hidden come above the keyboard 
        // 2. increase the size of the view so that the area behind the keyboard is covered up.
        rect.origin.y -= 140;
        rect.size.height += 140;
    } else {
        // revert back to the normal state.
        rect.origin.y += 140;
        rect.size.height -= 140;
    }

    self.view.frame = rect;

    [UIView commitAnimations];
}

As solved in comments above, code above works when view is not autoresizing. The simpler approach would be to use CGAffineTransform transformations that calculate view frame instead of you.

-(void)setViewMovedUp:(BOOL)movedUp {
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5]; // if you want to slide up the view
    [UIView setAnimationBeginsFromCurrentState:YES];

    if (movedUp) {
        self.transform = CGAffineTransformMakeTranslation(0, -150);//move up for 150 px
    } else {
        self.transform = CGAffineTransformIdentity;//reset to initial frame
    }

    [UIView commitAnimations];
}
