For example, say you wanted to create a Flipboard or Paper like interface, where you have a screen shot of a UIVIew, and you want to have the appearance of it folding. To do this you can use the CGImageCreateWithImageInRect method in objective-c. The code below is an example of how to use this method. In this scenario we're splitting the image in half, a left and right image. -(void)splitImage:(UIImage *)image{ CGFloat imgWidth = image.size.width/2; CGFloat imgheight = image.size.height; CGRect leftImgFrame = CGRectMake(0, 0, imgWidth, imgheight); CGRect rightImgFrame = CGRectMake(imgWidth, 0, imgWidth, imgheight); CGImageRef left = CGImageCreateWithImageInRect(image.CGImage, leftImgFrame); CGImageRef right = CGImageCreateWithImageInRect(image.CGImage, rightImgFrame); UIImage* leftImage = [UIImage imageWithCGImage:left]; UIImage* rightImage = [UIImage imageWithCGImage:right]; CGImageRelease(left); CGImageRelease(right);} To do this, we first figure out the clipping area we want for each image. In the case above, the left side will consist of an x of zero and the width divided by 2. While for the right image, we use the same width but make the x start at where the left image ended. NOTE You must release the CGImageRef when you're finished with it, otherwise there will be a memory leak. Enjoy By Stephen Zaharuk (SteveZ)
