FTGNotificationController

Simple and safe way to observe notification

How I do it

• Modify Facebook 's KVOController to work with NSNotificationCenter

How to use it

• Example

self.notificationController = [FTGNotificationController controllerWithObserver:self];
    [self.notificationController observeNotificationName:UIApplicationDidReceiveMemoryWarningNotification
                                                  object:nil
                                                   queue:[NSOperationQueue mainQueue]
                                                   block:^(NSNotification *note, id observer)
    {
        NSLog(@"observer %@ notification payload %@", observer, note);
    }];

• To automatically remove observers on observer dealloc, declare FTGNotificationController as strong property
• Do not use self inside block as it causes retain cycle. Declare weak self or use observer parameter (declared as weak for you)
