I understand it’s possible to Detecting programmatically whether an app is installed on iPhone . I’m wondering if it’s possible to detect what version of the other app is installed?
My app has a dependency on the Facebook native client, but behaves pretty badly if the phone has an older version of the Facebook app installed. So I’d like to be able to detect that and warn users.
— UPDATE —
It’s being implied in the comments that I can prevent users from installing my app in the first place if the appropriate version of the dependent app is not present. That would be a great solution too. If you know how I can specify a dependency on another app’s version number, please explain that.
Unfortunately, you can not read your iOS device settings programmatically to get the native app Facebook version (i.e. via Settings, Facebook, Version).

It seems the different versions of the native Facebook application either support/does not support its own custom URL schemes.
As noted here from version 3.4, you can:
From version 4.0, as noted here, you can:
