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?

Answer 1

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.
