Question

I’m having a weird behavior in my app. I’m populating my views with data from the database and sometimes the views are empty and i don’t know the cause. It’s like the database is closed or something so i was thinking to use some delegate methods to close and open the database to see if it fixes the problem. So the question is what of these three methods should i use and if this is a good approach?

applicationWillResignActive
applicationDidEnterBackground
applicationWillTerminate

So those are to close the database, to open the database should i use a notification like:

UIApplicationWillEnterForegroundNotification

Thanks in advance.

Well be aware that viewDidUnload can still be called when your app is in the background and the OS need memory.
So when you clear any object in the viewDidUnload and not set them in the viewDidLoad then your views could be empty.
