How to make one color transparent on a UIImage?

I've some images came from Server as URL and then I download and draw them on Cells of UITableView.

The images have white background. I need to remove this background to make the image transparent.

I'll rephrase it: Is there a way to detect and recognize white spaces surrounding the component inside the photo, So I delete them and recreate the image? you know like face recognition.

Note: the background is part of the image itself.

  • Have a look at the link left by @MattB, but if the image is a JPEG, I do not think it will be that easy. – Mike D Oct 23 '12 at 18:42
