Question

I am trying to create a TIFF image from a UIImage. I looked into Apple\'s docs but could not find any information.

Can anyone help me and

I feel like this answer is a little late, but in case someone else wants to know how to do this, I think you'll find the following will do the trick:

NSMutableData *mData = [NSMutableData dataWithCapacity:SOME_BIG_NUMBER];
CGImageDestinationRef myImageDest = CGImageDestinationCreateWithData((__bridge  CFMutableDataRef)(mData), kUTTypeTIFF, 1, NULL);
CGImageDestinationAddImage(myImageDest,image.CGImage, NULL);
CGImageDestinationFinalize(myImageDest);
CFRelease(myImageDest);

The mData will then hold NSData encoding of a TIFF file which you can then store to the disk, upload to a server, whatever...

You might need to include MobileCoreServices and ImageIO frameworks...
