Convert UIImage to CVImageBufferRef

Question

This code mostly works, but the resulting data seems to loose a color channel (is what I am thinking) as the resulting image data when displayed is tinted blue!

Answer 1

If anyone is still looking for a solution to this problem, I solved it by switching the BOOLs in the pixelBuffer's options:

NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
                     [NSNumber numberWithBool:NO], kCVPixelBufferCGImageCompatibilityKey,
                     [NSNumber numberWithBool:NO], kCVPixelBufferCGBitmapContextCompatibilityKey,
                     nil];

From NO to YES:

NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
                     [NSNumber numberWithBool:YES], kCVPixelBufferCGImageCompatibilityKey,
                     [NSNumber numberWithBool:YES], kCVPixelBufferCGBitmapContextCompatibilityKey,
                     nil];
