Question

I currently have two arrays, 1 in each class, but I am cloning them before displaying the other viewController. So whatever happens e.g. delete an item in one viewController, I clone the array for the other ViewController when it needs it.

What is the best way to make these ViewControllers read and write to the same array? I would like a shared array resource which I can access, modify from the 2 viewControllers, possibly a third, whenever necessary.

How is this done without cloning all the time.

Answer 1

You can create a singleton class which holds the array, then access it through the sharedInstance. I recommend this article for a review of the various approaches to this situation.
