In this lists' archives I found the hint to use the following;
instead of having to bother with an NSTimers' overhead:
[self performSelector:@selector(someSelector) withObject:nil
afterDelay:0.04]
Simplisticly put: (how) can I use that like this:
[self myCounter++ afterDelay:0.04]
How is the counter being used? Do you actually need to increment it
every 0.04 seconds or can you just add the appropriate number of
ticks based on the elapsed time every time you read it?
If you're literally just incrementing the counter without any side
effects then you're wasting a load of cycles and forcing your process
to schedule more often than it needs to.
