Question

In in my app, say it count downs to something and at the end just beeps forever until the user quits the app, is it safe to say have an NSTimer and never release (or in NSTimer’s case, invalidate it) it, since it will need to stay until the user quits the app?

Answer 1

Technically, yes, but I’ve found two things to be true:

• This is an easy habit to get in to, convincing yourself that X doesn’t need to be released because you’ve convinced yourself it needs to live forever when it doesn’t and leaks, or
• At some point in the future you’ll realize you really want to be able to control that timer after all, and setting up the ivar now will save you a heap of trouble down the road (no pun intended)
