Answer 1

#import <QuartzCore/QuartzCore.h>  CALayer *imageLayer = YourImageview.layer;         [imageLayer setCornerRadius:5];         [imageLayer setBorderWidth:1];         [imageLayer setMasksToBounds:YES]; 

by increasing radius it will become more round-able.

As long as the image is a square, you can get a perfect circle by taking half the width as the corner radius:

[imageView.layer setCornerRadius:imageView.frame.size.width/2];  

You also need to add

[imageView.layer setMasksToBounds:YES]; 

Swift 4.2

import QuartzCore  var imageLayer: CALayer? = YourImageview.layer imageLayer?.cornerRadius = 5 imageLayer?.borderWidth = 1 imageLayer?.masksToBounds = true
