IOS: create a UIImage or UIImageView with rounded corners

Is it possible create an UIImage or an UIImageView with rounded corners? Because I want take an UIImage and show it inside an UIImageView, but I don't know how to do it.

Solution 1:

Yes, it is possible.
Import the QuartzCore (#import <QuartzCore/QuartzCore.h>) header and play with the layer property of the UIImageView.

yourImageView.layer.cornerRadius = yourRadius;
yourImageView.clipsToBounds = YES;

See the CALayer class reference for more info.

Solution 2:

Try this Code For Round Image Import QuartzCore framework simple way to create Round Image

imageView.layer.backgroundColor=[[UIColor clearColor] CGColor];
imageView.layer.cornerRadius=20;
imageView.layer.borderWidth=2.0;
imageView.layer.masksToBounds = YES;
imageView.layer.borderColor=[[UIColor redColor] CGColor];

Solution 3:

Objective-C

-(UIImage *)makeRoundedImage:(UIImage *) image 
                      radius: (float) radius;
{
  CALayer *imageLayer = [CALayer layer];
  imageLayer.frame = CGRectMake(0, 0, image.size.width, image.size.height);
  imageLayer.contents = (id) image.CGImage;

  imageLayer.masksToBounds = YES;
  imageLayer.cornerRadius = radius;

  UIGraphicsBeginImageContext(image.size);
  [imageLayer renderInContext:UIGraphicsGetCurrentContext()];
  UIImage *roundedImage = UIGraphicsGetImageFromCurrentImageContext();
  UIGraphicsEndImageContext();

  return roundedImage;
}

Swift 3

func makeRoundedImage(image: UIImage, radius: Float) -> UIImage {
    var imageLayer = CALayer()
    imageLayer.frame = CGRect(x: 0, y: 0, width: image.size.width, height: image.size.height)
    imageLayer.contents = image.cgImage

    imageLayer.masksToBounds = true
    imageLayer.cornerRadius = radius

    UIGraphicsBeginImageContext(image.size)
    imageLayer.render(in: UIGraphicsGetCurrentContext())
    var roundedImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    return roundedImage
}

Solution 4:

uiimageview.layer.cornerRadius = uiimageview.frame.size.height/2;
uiimageview.clipToBounds = YES;

#import <QuartzCore/QuartzCore.h>
