I am totally new to ios developement/siganlr. what i'm trying to do is connect signalr-objc client to get long-polling feed from .net api.

It work fine on javascript:

var connection = $.hubConnection();
connection.url = "http://HOST:8080/live";
connection.qs = { 'group': 'default' };
connection.start({ transport: ['longPolling'] }).done(function() {
    console.log('Proxy Started');
});
var myHubProxy = connection.createHubProxy('quotesHub');
myHubProxy.on('update',callback);

pod file: platform :ios, '6.0' pod 'AFNetworking' pod 'SignalR-ObjC', '2.0.0.alpha1'

SRHubProxy *myHub

- (void)viewDidLoad {
    [super viewDidLoad];
    SRHubConnection *hubConnection = [SRHubConnection           connectionWithURL:@"http://HOST:8080/live"];
    myHub = [hubConnection createHubProxy:@"quotesHub"];
    [hubConnection start];
}

  • You haven't stated what the issue is. You just show a bunch of log output with no explanation of any kind. And this is tagged as Objective-C. There's no Objective-C code in your question. – rmaddy Feb 16 '15 at 04:08
  • i apologize for did not state clearly my question. My question is when i build the app and it throw me the log as above.

The message you are receiving after every 1/2 min. state like you are connected with SignalR i.e HUB name that you want to connect. In your case that is "quotesHub".

Now you have to call hub invoke method. (the method name is scripted on .net side We have to call that function)

Let's take example : There is one function name as "send" on asp.net script side. For sending message I have to call that function. There is two parameter that used in that function. First is name and second is message.

By below code i can do that thing 

    NSArray * ar = [[NSArray alloc] initWithObjects:@"Andrew Taylor",@"Hi", nil];
    [_hub invoke:@"send" withArgs:ar completionHandler:^(id response)
     {
         NSLog(@"hubResult %@",response);
     }];
