OK! Easy fixes. First, instead of @interface UIImage () you want @interface UIImage (PrivateRoundedCorner). Then it will compile without errors. The “Private” is because this is, literally, a private extension. Next, in UIImage+Resize.m, you will want to handle ALL UIImageOrientation values. Just break on the unused ones. That’s it!

Strangely, when i use the resize method, i get this error :

unrecognized selector sent to instance *** Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘-[UIImage resizedImage:interpolationQuality:]”

UIImage *displayFinalImage = [_finalImage resizedImage:(_viewCanvas.frame.size) interpolationQuality:kCGInterpolationHigh];

what am i doing wrong?

I’ve forked Trevor’s original code and put it up on GitHub for anyone who wants an updated copy. This fork includes a couple updates of my own, as well as the bug fixes written here in the comments.

I’ve been using this in my own iOS projects for about a year and it’s pretty stable AFAIK, but open an issue if you notice any bugs! I plan to keep it updated for future changes in the iOS SDK.

I am getting a SIGBART error when I add this updated code. Can you provide some guidance?
