How to center a subview of UIView

I have a UIView inside a UIView and I want the inner UIView to be always centered inside the outer one, without it having to resize the width and height.

I've set the struts and springs so that it's on top/left/right/bottom without setting the resize. But it still doesn't center. Any idea?

Solution

  • Objective-C

    yourSubView.center = CGPointMake(yourView.frame.size.width  / 2, 
                                 yourView.frame.size.height / 2);

    Swift

    yourSubView.center = CGPoint(x: yourView.frame.size.width  / 2,
                             y: yourView.frame.size.height / 2)
