I want my UIButton to make a UIAnimation where it gets resized and repositioned when clicked. But it seems this can't be done when the UIButton is using auto layout.

This is the code I want to perform:

- (IBAction)buttonClicked:(id)sender {
     [UIView beginAnimations:nil context:nil];
     [UIView setAnimationCurve:UIViewAnimationCurveLinear];
     [UIView setAnimationDuration:.15];
     [button setFrame:CGRectMake(100, 50, 20, 20)];
     [UIView commitAnimations];
}

But as long as this button uses auto layout and contraints the animation won't be performed. What is the solution here? Work around?

You need to modify the constraints, not the frame. – Paulw11 Jun 18 '16 at 09:05
@Paulw11 is it posible to ignore the constrains some how? Or remove them? – Peter Jun 18 '16 at 09:08
Only by not using autolayout. Animating the constraints is quite straightforward. See the duplicate – Paulw11 Jun 18 '16 at 09:09
You can create @IBOutlets for the constraints that you want to change just like you do for the button itself – Paulw11 Jun 18 '16 at 09:12
