Did you end up figuring it out? I saw that you said that you cannot invalidate your timer when you go into another view. Can you explain what you mean by that? NSTimers cannot be paused, and methods to simulate pausing them usually involve invalidating them. You can then simulate "unpausing" by creating a new timer that will then start up again. This will simulate a timer being paused and unpaused.

For people who would like a potentially more convenient method, I wrote a controller class that can conveniently handle pausing and unpausing timers. You can find it here: https://github.com/LianaChu/LCPausableTimer

You can use the controller class that I wrote to create new timers, and then you can pause and unpause the timers by call the methods "pauseTimer" and "unpauseTimer" on the controller class.

I would greatly appreciate any comments or feedback like how you used it, what changes you would like to see, or any features you would like me to add. Please don't hesitate to reply with your comments here, or post on the issues tab on the Github page.
