Circular UIImageView in UITableView without performance hit?

Question

I have a UIImageView on each of my UITableView cells, that display a remote image (using SDWebImage). I\'ve done some QuartzCore

Answer 1

If you showing the images over a solid background color, an easy solution could be to use an overlay image with a transparent circle in the middle.

This way you can still use square images and add the circle image above them to get the circular effect.

If you don't need to manipulate your images or show them on a complex background color, this can be a simple solution with no performance hit.
