Is there a way to get access to the CADisplayLink in the runtime?

Hello,
@Simeon mentioned earlier that he was looking into keeping the Codea frame from pausing when a UIScrollView was scrolled, but his method made everything choppy. I decided to look into the issue more today, and found that people suggest doing this by calling this code on the CADisplayLink: [displayLink addToRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
However, I don’t seem to have access to the CADisplayLink.
Is there any way I can get access to it?
Thank you!
