Ich habe versucht, TableView-Daten von AppDelegate.m neu zu laden, aber ohne Erfolg.

Hier ist Code (der in HomeViewController funktioniert):

AppDelegate.m

<code>...
- (void)applicationWillEnterForeground:(UIApplication *)application
{
[self refreshTableData];
}

-(void)refreshTableData{

    UINavigationController *navController = [[self.tabBarController viewControllers] objectAtIndex:0];
    HomeViewController *home = [[navController viewControllers] objectAtIndex:0];

    NSEntityDescription *entity = [NSEntityDescription entityForName:@"MYTable" inManagedObjectContext:home.context];

    NSFetchRequest *request = [[NSFetchRequest alloc] init];

    [request setFetchBatchSize:20];

    [request setEntity:entity];

    NSSortDescriptor *sort = [[NSSortDescriptor alloc] initWithKey:@"orderEnt" ascending:YES];

    NSArray *newArray = [NSArray arrayWithObject:sort];

    [request setSortDescriptors:newArray];

    NSError *error;

    NSMutableArray *results = [[home.context executeFetchRequest:request error:&error] mutableCopy];

    [home setArr:results];

    //NSLog(@"%@", home.arr);//here is showed correct data

    home.context = self.managedObjectContext;

    [home.myTableView reloadData];


}
...
</code>

Weiß jemand, wie man Daten von AppDelegate.m nachlädt?
