In Cocos2d documents it is written that it is not a good idea to use NSTimer. Why is it not recommended to use NSTimer. I know there is a schedule method of Cocos2d.

    Try NOT to use Cocoa’s NSTimer. Instead use cocos2d’s own scheduler.
    If you use cocos2d scheduler, you will have:

    • automatic pause/resume.
    • when the
      CCLayer (CCScene, CCSprite, CCNode)
      enters the stage the timer will be

      • automatically activated, and when it
        leaves the stage it will be
      • automatically deactivated. Your
        target/selector will be called with a
        delta time

    from here (old broken link)

    updated link

    I would add you are adding some unwanted overhead too. If you have a lot of timers that could be a good bit of overhead.
