Question

I want to use the singleton UIApplication to access the managedObjectContext of the AppDelegate. But when I write

[[[UIApplication sharedApplication] delegate] managedObjectContext]

or

[[[UIApplication sharedApplication] delegate] __managedObjectContext]

it doesn’t work.

But this line works fine :

NSLog(@"Seeking for the AppDelegate : %@", [[[UIApplication sharedApplication] delegate] class]);

Do you have a solution ?

Try casting it to your actual app delegate implementation, like

 [(MyAppDelegate *)[[UIApplication sharedApplication] delegate] managedObjectContext];

And to add

#import "MyAppDelegate.h"

at the top of the file.
