Tab Bar Application, ManagedObjectContext

Question

hi, I have this tab bar application, I have 1 tab setup correctly with a drill down navigation/table view controller which display information and details of Entity A ; And now I want to create a new tab which display another set of drill down and displaying information of Entity B which both entity has no relations.

I tried to use the same code as Entity A Nav/TableViewController, and I got an error and crash

reason: '+entityForName: could not locate an NSManagedObjectModel for entity name 'EntityB''

I use the example in RecipesApps and have this in the app delegate

entityAListController.managedObjectContext = self.managedObjectContext; 

I am a newbie and I am sure something needs to fix for the managedObjectContext, please point me to the right direction, possibly with example and where the code should belong.

Greatly appreciated~

Hi,

Does your xcdatamodel contain EntityB ?
