Check if managedobjectcontext is empty?

Question

In my application I want to make it so that when the user opens the application and there are no objects, i want it to add an object to the first section of the table view. I know in my App Delegate in the method:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

I can do something like this:

if (XXXXXX){    
NSManagedObjectContext *context = self.managedObjectContext;
        NSManagedObject *startingTask = [NSEntityDescription insertNewObjectForEntityForName:@"Tasks" inManagedObjectContext:context];
        [startingTask setValue:@"Eat Dinner" forKey:@"taskName"];
        [startingTask setValue:[NSNumber numberWithDouble:400] forKey:@"timeInterval"];
        [startingTask setValue:@"Tasks To Complete" forKey:@"sectionString"];
}

where XXXXX checks whether the managedobjectcontext is empty (or basically, there are no objects to fetch).

but what would be XXXXX?

Answer 1

Just perform the fetch you would normally perform to fill your table. If it returns no records, then the store is empty for your purposes. That's the question you really want to know about.

It's possible that there might be records in the same persistent store that aren't related to your table records, so don't worry about the exact number of total entities in the store for this kind of problem. (Don't assume you model will never change; it's complely legal to put independent entities into a store.)
