iOS7 + Sprite Kit: How can I keep one timer displayed constantly if I'm changing scenes?

Question

I'm working on a game using Sprite Kit where the user needs to solve as many puzzles in a given period of time. Every time a puzzle is solved correctly, a new game scene is created with a new puzzle and displayed. I created a timer for the scenes, but it restarts every time a new scene is generated. Is there a way to keep one timer displayed for multiple scenes?

Answer 1

You should use a singleton file to store this so it will be the only one when you change the scene or anything.

Answer 2

If you have one view controller presenting all the scenes, you can attach the timer to that view controller rather than the scenes.

Answer 3

Create and store the timer object and the related data in your view controller instance, or subclass the SKView and store it there. This will retain any object for the lifetime of the view.
