In general, you are discouraged from retrieving resources such as this
from the application delegate. Instead, you should pass resources
directly to view controllers. This is the pattern shown in the Core
Data templates and related sample code, e.g.
- (void)applicationDidFinishLaunching:(UIApplication *)application {
RootViewController *rootViewController = (RootViewController *)
[navigationController topViewController];
rootViewController.managedObjectContext =
self.managedObjectContext;
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
}
This typically makes your view controllers more self-contained and
reusable.
