Load Native FB app from AIR mobile IOS

I am trying to bring up a native Facebook feed from an air mobile app with no
success. The code works fine on Android, but on IOS it opens the native app
but will not load the users page. I am using this as a URL request
fb://pages/{users ID}

tried an IOS 7 and IOS 8, phone and tablet with no success. Has anyone else
had a problem or been able to accomplish this?

thanks,

Aaron
