bundling Core Data to tableviewcontroller (himself in a navigation controller(himself in a tabbarcontroller))

I'm new on developping on iPhone and I encounter pretty much problem with my project.

The project, based on empty app : a tabbar app(item1,item2). item1 is a simple viewcontroller(ProfilViewController) and is part of navigationcontroller. a button from item1 push a tableviewcontroller (MainMantraViewController).

Aside, I have my CoreData with a single entity : Mantra,made of 3 attributes:phrase,theme,partage. I try to fill it at the launch to test the bundle between coredata and the tableviewcontroller.

here is my appdelegate.m, under didfinishlaunching:

ProfilViewController *rootView =(ProfilViewController *)self.window.rootViewController;
rootView.managedObjectContext=self.managedObjectContext;

//donnée test
Mantra * newMantra=(Mantra *)[NSEntityDescription insertNewObjectForEntityForName:@"Mantra" inManagedObjectContext:self.managedObjectContext];
newMantra.phrase =@"ca pu du cul";
newMantra.theme = @"rire";

Runnning the app, I get the following *

*:

**2012-05-24 16:26:09.690 Proto v0[1843:fb03] -[UITabBarController setManagedObjectContext:]: unrecognized selector sent to instance 0x6a4a690
2012-05-24 16:26:09.693 Proto v0[1843:fb03] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UITabBarController setManagedObjectContext:]: unrecognized selector sent to instance 0x6a4a690'**

I'm completly stucked at this point and i can't find any conclusive clue anywhere. I thank you for your help and will provide any helpfull snipets.

Cheers

Well, the error log is clear enough, you are calling 'topViewController' somewhere on the UITabBarController, but UITabBarController doesn't have a property called 'topViewController'. I think you want to use 'selectedViewController'.
