Who can help me figure out SignalR?

Question

Objective-C

Hello!
There is a need to use SignalR. Looks like I found some tutorials. Connected, everything is ok. But here's what comes.

// Connect to the service
    SRHubConnection *hubConnection = [SRHubConnection connectionWithURLString:@"http://app.plugmee.com/signalr/"];
    
    [hubConnection addValue:[self.userDefaults objectForKey:@"login"] forHTTPHeaderField:@"User-Id"];
    
    // Register for connection lifecycle events
    [hubConnection setStarted:^{
        NSLog(@"Connection Started");
    }];
    
    [hubConnection setReceived:^(NSString *message) {
        NSLog(@"Connection Recieved Data: %@",message);
    }];
    
    [hubConnection setConnectionSlow:^{
        NSLog(@"Connection Slow");
    }];
    
    [hubConnection setReconnecting:^{
        NSLog(@"Connection Reconnecting");
    }];
    
    [hubConnection setReconnected:^{
        NSLog(@"Connection Reconnected");
    }];
    
    [hubConnection setClosed:^{
        NSLog(@"Connection Closed");
    }];
    
    [hubConnection setError:^(NSError *error) {
        NSLog(@"Connection Error %@",error);
    }];
    
    // Start the connection
    [hubConnection start];

I am not asking you to solve my problem. I would be very grateful for an adequate tutorial (preferably in Russian, English is not very good, but it will do in English too).
Thanks in advance!

Answer 1

Is there a problem with SRWebSocket too? It will be simpler, SignalR is based on it, configured in 3 lines, if there are problems through it, then the matter is in the server. I don't see any such errors.
