I have been using the Facebook iOS SDK for sharing messages . Recently i updated the Xamarin as well as FACEBOOK IOS SDK to 4.80. After updating , the app crashes as soon as it opens. We removed the component and its related code and everything seems to work fine without the component.
Below are the exception which we found in the device logs , which seems to be in internal methods of Facebook SDK :-
I had done some R&D and tried the below fixes which did not worked out.
1)Added ATS for Whitelist (https://components.xamarin.com/gettingstarted/facebookios)
2)Added LSApplicationQueriesSchemes keys (https://components.xamarin.com/gettingstarted/facebookios)
Below are the details of environment in which we found the issue.
Component name: FaceBook iOS SDK
Updated Version : 4.80
Updated date : Friday 4th Dec 2015
Xcode Version : 7.2
Xamarin Version : 5.10.1 (Build 6)
iOS version : 9.2
You can find the similar issue in this link (https://bugzilla.xamarin.com/show_bug.cgi?id=11041).
Test case: https://drive.google.com/a/xamarin.com/file/d/0B_5pvct1AELzOXRvSmZ6aUlidEU/view?usp=sharing
Based on your test case, adding the "Whitelist Facebook Servers for Network Requests":
and adding the "Whitelist Facebook Apps" for FB iOS v4.6 or later:
to the Info.plist, solved the problem. You need these permission so you can use FB iOS SDK on iOS 9.0 or later.
