Timer decrement gets varied for each page load

Question

I have a timer for my project, each time it decrements by 1 second. But if the counter starts working for the second time it gets decremented by 2 seconds and for the third

Answer 1

From what you've posted, you're creating multiple timers and not stopping any of them. So after 3 times, you have 3 timers firing each second.

At a minimum, when the timer hits zero you want to invalidate it:

[theTimer invalidate]

But you may also want to consider holding onto the timer you create (in a @property) so that you can invalidate and release it if the user leaves this view some other way before your counter actually goes to zero.

Hope that helps.
