SCNetworkReachabilityGetFlags returns 0 even when wireless available

Question

I have an app that uses Apples reachability code. When I tab out of the app, turn on airplane mode, go back into the app, I correctly get a message that says no connection i

Answer 1

If the flags were received and they end up being 0, as you've seen, this indicates Airplane Mode is on. However, the results of this check seem to be cached, at least for a short time. Try this: leave your app, turn Airplane Mode off, hit a site in Mobile Safari, then return to your app. This may invalidate the cache.
