Feature Request: Network Activity Indicator/Spinner

[daylen]

I know that AFNetworking has support for the iOS network activity indicator/spinner, but I looked everywhere and it doesn't seem like Alamofire supports this.

You are correct—Alamofire does not directly implement this functionality. My current thinking is that this should be handled entirely by a separate NSURLProtocol-based mechanism, which could be shared between AFNetworking and Alamofire.

@mattt I started going the NSURLProtocol route you mentioned, however got stuck pretty quickly while trying to implement my startLoading()/stopLoading() methods. From what I can tell, Alamofire currently does not expose much of its SessionDelegate class which manages the actual network callbacks for me to hook into (to hide the NetworkActivityIndicator once request completes).

Could you elaborate on your thinking a little more? Would that NSURLProtocol mechanism be able to fall back on most of the existing implementation of Alamofire or do you see the NSURLProtocol have its own NSURLSession and track its progress via its own delegate methods?

I just implemented this idea: https://github.com/marcelofabri/BigBrother

@marcelofabri But your implementation overrides whole Alamofire.Manager implementation. You replace NSURLSession with NSURLConnection and then methods of NSURLSessionDelegate can't be executed.
