Hi,
Thanks for the reply. My question was very vague, I admit.
But now I have moved to your suggestion.
I'm setting up the timer via [NSTimer scheduledTimerWithTimeInterval:
1.0 target: self selector: @selector(doSomething:) userInfo: nil
repeats: YES];
But the doSomething is not getting called at all.
May be because this thread is busy doing something else, so do I have
to setup the timer in say main Thread.
Earlier I was doing so, by setting up the timer by calling this
setting up method as [self performSelectorOnMainThread:............],
and it was working, but even after invalidating the timer, the timer
was still referencing the object that contained NSTimer *timer.
Any suggestions?

That's expected behavior - NSTimers retain their targets. The target
won't be deallocated until the timer has been invalidated (assuming
the timer was the only thing keeping the target alive.)

Woah, this sentence has my completely baffled:
o Prior to this sentence, you were talking about retaining/
releasing, not you're talking about garbage collection. I think I'm
still following you though - regardless, the timer is keeping the
target alive.
o 3-4 bytes of what? Why do these bytes matter?

Oh. I think you're just trying to have a method called every second.
If that's the case, no need to concern yourself with threads and...
well, whatever it is that's going on in that code snippet. :D
[NSTimer scheduledTimerWithTimeInterval: 1.0 target: self
selector: @selector(doSomething:) userInfo: nil repeats: YES];
That will call self's -doSomething: method every second. Is that
what you're trying to accomplish?
