If you store a timer in a member variable you should retain it. Because probably you created it using timerWithTimerInterval:

Anyhow. If your reference is valid you can check it using [myTimer isValid];

If you don’t retain your timer, you should at least assign nil after invalidating it.

[myTimer invalidate];
myTimer = nil;
