If you have a case where you'd like to know if your app doesn't have permission, can you describe it? Is this for using Bonjour, or a direct connection use case? I have an app that should connect to device AP to provision it via HTTP/HTTPS.
While iOS reconnects from home to device AP NSURLErrorNotConnectedToInternet error are quite expected. With existing API there is no way to distinguish "still connecting" and "no permission" state.
