MonoTouch (Xamarin.iOS) Facebook app switching support for iOS 5+

Question

Is there a solution out there where I can happily use the Facebook 3.1+ SDK, with MonoTouch, for iOS 5+ users?

For users NOT using iOS 6 I want my game to switch to the Facebook iOS app for authentication as normal (if they have it), to avoid the barrier of them entering credentials.

The Facebook iOS SDK 3.1+ (Obj-C) allows this functionality, and it uses the native library if users have iOS 6.

Unfortunately I'm unable to find that functionality for MonoTouch, where my app can easily switch to the Facebook app and quickly authenticate the user, for non iOS 6 users.

I've narrowed down my MonoTouch Facebook options to the following, none of them ideal:

1. Limit my game to iOS 6, which would allow me to use the monotouch-bindings/facebook native library

2. Use the Xamarin.Social component, which requires login details (no app switching) and has poor UI

3. Use a (unsupported since 2011) MonoTouch Facebook 3.0 library, there's a couple out there

4. Convert the latest Facebook 3.2.1 SDK to MonoTouch, allowing for non-native app switching

The ideal solution would be option 4, which would give the user the app switching experience on any version on iOS. Unfortunately I wouldn't have a clue where to start with that and I haven't got the time to spend a week trying to convert/bind (?) it.

I'm really not keen on limiting the app to iOS 6 users, we want the app to reach as many people as possible.

Thanks in advance for any suggestions and ideas.

The Monotouch binding for the 3.2.1 facebook SDK is here .

Last I used it, it seemed to do everything you want.
