How to keep a round imageView round using auto layout?

Question

How do I turn a rectangular image view into a circular image view that can hold shape in auto layout without setting width and height restraints? Thereby allowing the imageV

Answer 1

Add a 1:1 aspect ratio constraint to the imageView for it to remain circular, despite any height or width changes.

Answer 2

If you have subclassed the UIImageView. Then just add this piece of magical code in it.

Written in : Swift 3

override func layoutSubviews() {
    super.layoutSubviews()
    if self.isCircular! {
        self.layer.cornerRadius = self.bounds.size.width * 0.50
    }
}

Answer 3

create new interface in your .h file like

@interface CornerClip : UIImageView

@end

and implementation in .m file like

@implementation cornerClip


-(void)layoutSubviews
{
    [super layoutSubviews];

    CGFloat radius = self.bounds.size.width / 2.0;

    self.layer.cornerRadius = radius;

}

@end

now just give class as "CornerClip" to your imageview. 100% working... Enjoy
