Setting up reachability with AFNetworking 2.0

Question

I am trying to setup Reachability using the new 2.0 AFNetworking.

In my AppDelegate I initialise the sharedManager.

// Instantiate Shared Manager
[A

I have a singleton AFHTTPRequestOperationManager class. In the singleton has a method:

+(void)connectedCompletionBlock:(void(^)(BOOL connected))block {

[[AFNetworkReachabilityManager sharedManager] startMonitoring];

[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {

    BOOL con = NO;
    NSLog(@"Reachability: %@", AFStringFromNetworkReachabilityStatus(status));

    if (status == AFNetworkReachabilityStatusReachableViaWWAN || status == AFNetworkReachabilityStatusReachableViaWiFi) {

        con = YES;
    }

    if (block) {
        [[AFNetworkReachabilityManager sharedManager] stopMonitoring];
        block(con);
    }

}];

}

Before make a request you call this method that return a block indicating if internet is reachable:

[TLPRequestManager connectedCompletionBlock:^(BOOL connected) {
    if (connected) {

       // Make a request

    }else{

        UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"Notice" message:@"Internet is not available." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles: nil];

        [alertView show];

    }

}];
