Question

I am working on creating an image gallery which has thumbnails in different sizes. I want to convert these rectangle thumbnails to square size so that all of them could appear similar in size. I dont mind cropping it from extended portion but I am not sure how to do it. can anyone please help me?

Thanks

You need to use the image in rect method passing in the image and the required bounds…

CGImageRef imageRef = CGImageCreateWithImageInRect([anImage CGImage], requiredBounds);
UIImage *croppedImage = [UIImage imageWithCGImage:imageRef];
CGImageRelease(imageRef);

I have added this to a UIImage category (UIImage+Resize) in the following post, you can download the source code as well – Categories example
