Setting Corner Radius on UIImageView not working

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.

Also worth noting that

If you are using aspectFit AND cornerRadius with clipsToBounds/masksToBounds, you won't get the rounded corners.

i.e if you have this

theImageView.contentMode = .scaleAspectFit

and

   theImageView.layer.cornerRadius = (theImageView.frame.size.height)/2    theImageView.clipsToBounds = true

theImageView.layer.masksToBounds = true

It won't work. you will have to get rid of aspectFit code

//theImageView.contentMode = .scaleAspectFit

iphone ios uiimageview rounded-corners

This should work

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