I'm not using ARC so I can't use weak. Please let me know, that what can I do to not allow the NSTimer to retain the target which in my case is self.

    Why don't you want the timer to retain its target? Show your relevant code and explain what you are trying to do. – rmaddy Apr 22 '14 at 23:13

    unsafe_unretained. But why are you not using arc and why do you want to do what you describe in your question? – Gruntcakes Apr 22 '14 at 23:22

You might just go ahead and create a version of NSTimer that does not retain its target 

+ (NSTimer *) scheduledTimerWithTimeInterval:(NSTimeInterval)ti target:(id)aTarget selector:(SEL)aSelector userInfo:(id)userInfo repeats:(BOOL)yesOrNo
{
    NSWeakTimerTarget* timerTarget = [[NSWeakTimerTarget alloc] init];
    timerTarget.target = aTarget;
    timerTarget.selector = aSelector;
    timerTarget.timer = [NSTimer scheduledTimerWithTimeInterval:ti target:timerTarget selector:@selector(fire) userInfo:userInfo repeats:yesOrNo];
    return timerTarget.timer;
}

  • There are several things not to like with that gist. The most obvious one is evading one of Apple’s class prefixes—especially not NS. Honestly: **DO NOT DO THAT!** Ever. The rest is too long to fit this narrow comment box. I’ll post an answer later on. – danyowdee Apr 23 '14 at 09:07
