Question

I have a method in my app delegate that updates the badge count for the app’s icon. I want this method to also update something in another VC which is visible throughout the app (like a notification center) I have.

How can I do this?

The method looks like:

- (void) remedyERxInterface:(RSeRxInterface *)eRxInterface 
             didSynchronize:(BOOL)success pendingMessageCounts:(NSDictionary *)pendingMessageCounts {

    NSInteger messageTotal = 0;
    NSInteger refillRequests = [[pendingMessageCounts objectForKey:kRSQueuesRefillCount] intValue];
    NSInteger problems = [[pendingMessageCounts objectForKey:kRSQueuesProblemCount] intValue];
    NSInteger messages = [[pendingMessageCounts objectForKey:kRSQueuesMessageCount] intValue];

    if (0) {
        if (self.eRxModuleInboxMessageCount) {
            messageTotal = refillRequests + problems + messages;
        } else {
            messageTotal = refillRequests + problems + messages + 12;
        }
    } else {
        //Production
        messageTotal = refillRequests + problems + messages;
    }

    [UIApplication sharedApplication].applicationIconBadgeNumber = messageTotal;
    self.eRxModuleInboxMessageCount = messageTotal;
}

You mention a notification center. Have you looked into using NSNotifications through the NSNotificationCenter? It is ideal for a central entity to broadcast information without knowing who listens. You can just register your view controllers for these notifications with callbacks which will be called synchronously.
