How do I prevent Facebook on iOS 7 from accessing my location? I'm using Facebook on iOS 7. When I send a message, my location is included, and the prompt tells me how to turn it off permanently: Go to Settings > Privacy > Location Services and turn it off for Facebook. But Facebook doesn't appear as an app in Location Services. So, how do I prevent Facebook from accessing my location?

To be clear, the question is not about whether Facebook includes my location in messages. It's that I don't trust Facebook itself to access my location.
Indeed @cksum appears to be correct. I just tested this on my dev device that's never had Facebook installed. The app said that it knew my location and showed the blue location icon, but didn't show in the list of apps in Location Services.

I pressed 'send' and got the 'Facebook wants to use your location' message, which I accepted and now the app is in the list and allowed me to switch it off.

In conclusion, yes it appears that Facebook doesn't request the actual location data until you press send, at which point the app is added to the list in Settings.
