iphone - AFNetworking and No Internet Connection scenario

Question

I use AFNetworking in my app for every request (like login, get data from url, etc).

Take this for example: an user click on the login button and there's no connection, how to instantly display a UIAlertView that says the error? The only way is to wait the request timeout and execute the failure block? Isn't there a way that instantly check if there's connection or not?

Thanks!

As of 0.9, AFHTTPClient actually has network reachability built-in (a simpler interface to Apple's aforementioned Reachability code). Just include the SystemConfiguration framework and use -setReachabilityStatusChangeBlock: to specify a response when the reachability state changes.
