I’m actually struggling with the Sign in of my app. I created a loginOperation to perform the sign in request. But I don’t really know how to inform my viewController that the request is done, if it worked or not (e.g. invalid credentials).
Should I post a NSNotification from my operation and catch it in my viewController ?
Should I store the response status, catch it in the completion block of the NSOperation, and send it to my ViewController through a callback ?
