Diference between get Object using FetchResultController and ManagedObjectContext?

The point behind using an NSFetchedResultsController as opposed to just a NSFetchRequest is the monitoring of your data and the convenience methods when working with sections.

The NSFetchedResultsController object will tell you when the objects of your query change. Just provide a delegate object to receive the calls (see the doc for NSFetchedResultsControllerDelegate protocol). It also provide you with section management which is useful if you want to display the data in a table view.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
