how to replace NSTimer with CADisplayLink?

Question

I call a doPoof method using NSTimer as following:

[NSTimer scheduledTimerWithTimeInterval:0.2 target:self selector:@selector(doPoof:) userInfo:myCALayer repeats:FALSE];

How to replace the above using CADisplayLink instead of an NSTimer?

Why do you want to change away from NSTimer?

The point of using CADisplayLink is so that animations can be timed according to the video refresh interval.

For a simple, non-repeating, call, NSTimer is perfectly valid.

Well, I'm stuck with trying to debug problems with my animations using a sprite sheet. My guess the problem I have is that NSTimer not accurate enough and once in a while my animation doesn't hit exactly at a time when is should which leads to wrong contentsRect and displays me just a middle part of my sprite sheet instead of a piece that it should cut out....I want to try CADisplayLink in hope that it might help. – PrimeSeventyThree Jun 16 '11 at 12:53
