Come connettersi a un hub SignalR dall'app PhoneGap su iOS?

Sto tentando di creare un client iOS PhoneGap per un server di chat SignalR di base in esecuzione (ASP.NET MVC 4). Tutto funziona alla perfezione quando si accede da una pagina di un browser, ma non riesco a connetterlo dall'app PhoneGap. Ecco le parti pertinenti del mio codice:Come connettersi a un hub SignalR dall'app PhoneGap su iOS?

global.asax Server

protected void Application_Start() 
{ 
    // Register the default hubs route: ~/signalr * This must be registered before any other routes 
    RouteTable.Routes.MapHubs(new HubConfiguration { EnableCrossDomain = true }); 

    AreaRegistration.RegisterAllAreas(); 

    WebApiConfig.Register(GlobalConfiguration.Configuration); 
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); 
    RouteConfig.RegisterRoutes(RouteTable.Routes); 
}

web.config Server

<configuration> 
    <system.webServer> 
     <modules runAllManagedModulesForAllRequests="true"></modules> 
    </system.webServer> 
</configuration>

hub Server client

public class ChatHub : Hub 
{ 
    public void Send(string name, string message) 
    { 
     Clients.All.broadcastMessage(name, message); 
    } 
}

PhoneGap

      }).fail(function() { 
       alert("Failed to connect"); 
      }); 
     }); 
     </script> 
</body>

Ho attraversato un sacco di siti che parlano di parti e parti di esso, ma non riesco a capire.

Grazie in anticipo, Jason

Grazie per l'articolo dfowler. In realtà avevo rimosso la linea cors come menzionato nelle note come uno dei tanti passaggi di debug che ho fatto, ma non ha fatto alcuna differenza. In realtà non avevo mai trovato quel particolare articolo e sembra abbastanza buono, quindi lo esaminerò e vedrò se c'è qualcos'altro che potrebbe aiutare. – Jason

Hai mai avuto fortuna con questo? Stavo cercando di testare la stessa cosa. – user441521

Spero che questo aiuta. Da qui ->http://agilefromthegroundup.blogspot.com/2012/09/getting-signalr-and-phonegap-working.html
