CoreData Fetch, via AGCoreData (remote persistence)

Fetch

...
// create the CoreData util/helper (or plugin...)
AGCoreDataHelper *helper = [[AGCoreDataHelper alloc] initWithConfig:^(id<AGCoreDataConfig> config) {
  // apply some config options
    [config setManagedObjectModel:managedObjectModel];
    [config setBaseURL:baseURL];
    [config setAuthMod:myMod];
}];
// get the IMPORTANT managedObjectContext, from the plugin:
NSManagedObjectContext *context = helper.managedObjectContext;

// vanilla,standard CoreData work, to execute a fetch request.....
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription entityForName:@"Tag" inManagedObjectContext:context];
[fetchRequest setEntity:entity];


// add a notification, which is invoked, once the FETCH has been completed 
[[NSNotificationCenter defaultCenter] addObserverForName:@"AFIncrementalStoreContextDidFetchRemoteValues" object:context queue:[NSOperationQueue mainQueue]
    usingBlock:^(NSNotification *note) {
        NSDictionary *userInfo = [note userInfo];
        NSArray *fetchedObjects = [userInfo objectForKey:@"AFIncrementalStoreFetchedObjectsKey"];
  	
	// work with the received TAG objects:
}];

// perform the actual fetch (which translates into a HTTP GET against the AG backend)
NSError *error = nil;
[context executeFetchRequest:fetchRequest error:&error];        

Save

...
// create the CoreData util/helper (or plugin...)
AGCoreDataHelper *helper = [[AGCoreDataHelper alloc] initWithConfig:^(id<AGCoreDataConfig> config) {
  // apply some config options
    [config setManagedObjectModel:managedObjectModel];
    [config setBaseURL:baseURL];
    [config setAuthMod:myMod];
}];
// get the IMPORTANT managedObjectContext, from the plugin:
NSManagedObjectContext *context = helper.managedObjectContext;

Tag *tag = [NSEntityDescription insertNewObjectForEntityForName:@"Tag" inManagedObjectContext:context];
tag.title = @"My Tag";
...

// Save everything (causes a HTTP POST, against the AG backend)
NSError *error = nil;
if ([context save:&error]) {
    NSLog(@"The save was successful!");
    _finishedFlag =YES;
} else {
    NSLog(@"The save wasn't successful: %@", [error userInfo]);
}
