Setting Corner Radius on UIImageView not working

Question

I\'m at a bit of a loss. I\'ve used the layer property of UIView to round the corners of multiple elements in my app. However, this one UIImageView is simply not complying.

Answer 1

You need to set the layer's masksToBounds property to YES:

cell.previewImage.layer.masksToBounds = YES;

This is because the UIImageView control creates a pseudo-subview to hold the UIImage object.

Answer 2

Try this code:-

self.imgaviewName.clipsToBounds = true
self.imageviewName.layer.cornerRadius = 10

Answer 3

I believe you need to set:

cell.previewImage.layer.masksToBounds = YES;
cell.previewImage.layer.opaque = NO;

Answer 4

For imageView.contentMode = .scaleAspectFill the cornerRadius is not applied if the image is very large, depending on the hardware.

Some tests with resized panorama images:

• iPhone X, image size 5000x1107:

Answer 5

Try this below piece of code

cell.previewImage.layer.cornerRadius = 20;
cell.previewImage.clipsToBounds = YES;
