Does Apple's Reachability class need to be included in an app that allows sharing via the built-in Facebook and Twitter sharing sheets? That's the only area of my app that would require any kind of network call, but since it's a system level function and my app isn't directly talking to Twitter/Facebook, I thought I might not need to include it.
On a related note, if my app sends a user to Safari for a help page, do I need to include Reachability for that? My app wouldn't be making any network calls there, either.
