Last part of the iTahDoodle app is to have the array saved to disk. As I understand it, purpose of this is so that closing the app and reopening will retain the array as it was prior to closing.
But my array stick around without implementing this extra code.
Now, if I FORCE close the app, the whole thing crashes (in the simulator). But simply pressing the home button and then opening the app back up will show the retained list.
So what is that extra ‘writeToFile’ method actually doing?
