Question

I am trying to mask an image so that I can give it only two rounded corners. With the code that I have it just adds the mask in white over the image, but doesn\'t seem to a

Round two corners in UIView

As mentioned in the above linked question, you probably need to remove the view from the heirarchy before applying its mask.

[self.imageView removeFromSuperview];
self.imageView.layer.mask = maskLayer;
[self.view addSubview:self.imageView];

Also, your maskLayer has no bounds. You need to set it to the frame (or bounds) of the view you're trying to mask.

CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.frame = self.imageView.frame;
