NSTimer doesn't stop

I am using [NSThread exit] to leave the NSTimer thread.
It stops the application entirely.

How do you stop or exit NSTimer thread?

Answer 1

If you want to definitely stop a NSTimer you may use

[timer invalidate];

However, if you want to temporary prevent the timer to fire you may consider using

[timer setFireDate:[NSDate distantFuture]];

From Apple Documentation:

Once scheduled on a run loop, the timer fires at the specified interval until it is invalidated. A non-repeating timer invalidates itself immediately after it fires. However, for a repeating timer, you must invalidate the timer object yourself by calling its invalidate method. Calling this method requests the removal of the timer from the current run loop; as a result, you should always call the invalidate method from the same thread on which the timer was installed. Invalidating the timer immediately disables it so that it no longer affects the run loop. The run loop then removes and releases the timer, either just before the invalidate method returns or at some later point. Once invalidated, timer objects cannot be reused.
