SRServerSentEventsTransport cannot negotiate with server

[chinaofmelon]

When I use SRServerSentEventsTransport, signalr always failed to connect to the server.I check the code found that block always be nil. when I fill the block, signalr work. How should I use this? And if I change this code, what's problem can be caused? The error code:

https://github.com/DyKnow/SignalR-ObjC/blob/feature-dev/SignalR.Client/Transports/SRServerSentEventsTransport.m
`

• (void)negotiate:(id)connection connectionData:(NSString *)connectionData completionHandler:(void (^)(SRNegotiationResponse * response, NSError *error))block {

  SRLogSSEDebug(@"serverSentEvents will negotiate");

  [super negotiate:connection connectionData:connectionData completionHandler:nil];

}

We use the serversentevents heavily, so I am guessing there is something we are missing. Are you saying you use SRServerSentEventsTransport directly?

@joeldart found this bug while working on the feature-afnetworking3x branch. You wont hit it when using the autotransport. Just if using sse directly.

@joeldart I am only use it for a test. For our debug server environment, SRWebSocketTransport and SRLongPollingTransport are working. When I use this, my colleague want to know if all of the transport are worked, so I found this issue. And I want to comfirm it.
