Answer 1

I suggest following the instructions from Facebook to prepare an app for iOS 9: https://developers.facebook.com/docs/ios/ios9

1. Download the latest Facebook SDK for iOS

Download the appropriate version of the Facebook SDK for your app.

v4.x - Recommended. v3.24.0 - Only if you have not migrated to v4.x of the SDK yet. 2. Whitelist Facebook Servers for Network Requests

If you compile your app with iOS SDK 9.0, you will be affected by App Transport Security. Currently, you will need to whitelist Facebook domains in your app by adding the following to your application's plist:

NSAppTransportSecurity

    NSExceptionDomains
    
        facebook.com
        
            NSIncludesSubdomains
                            
            NSExceptionRequiresForwardSecrecy
            
        
        fbcdn.net
        
            NSIncludesSubdomains
            
            NSExceptionRequiresForwardSecrecy
            
        
        akamaihd.net
        
            NSIncludesSubdomains
            
            NSExceptionRequiresForwardSecrecy
            
        
    

or you will encounter errors like:

NSUnderlyingError=0x7f88f9436eb0 {Error Domain=kCFErrorDomainCFNetwork
Code=-1200 "An SSL error has occurred and a secure connection to
the server cannot be made." UserInfo={NSErrorFailingURLStringKey=
https://graph.facebook.com/v2.4, NSLocalizedRecoverySuggestion=
Would you like to connect to the server anyway?,
_kCFNetworkCFStreamSSLErrorOriginalValue=-9802,
kCFStreamPropertySSLPeerCertificates={type = immutable, count = 2, values = (
0 : 
1 :  )}, 
_kCFStreamPropertySSLClientCertificateState=0,
kCFStreamPropertySSLPeerTrust=,
NSLocalizedDescription=An SSL error has occurred and a secure connection
to the server cannot be made.,_kCFStreamErrorDomainKey=3,
NSErrorFailingURLKey=https://graph.facebook.com/v2.4,
_kCFStreamErrorCodeKey=-9802}}

3. Whitelist Facebook Apps

If you use any of the Facebook dialogs (e.g., Login, Share, App Invites, etc.) that can perform an app switch to Facebook apps, you will need to update your application's plist to handle the changes to canOpenURL described in https://developer.apple.com/videos/wwdc/2015/?id=703

If you're recompiling with iOS SDK 9.0, add the following to your application's plist if you're using a version of the SDK v4.5 or older:

LSApplicationQueriesSchemes

    fbapi
    fbapi20130214
    fbapi20130410
    fbapi20130702
    fbapi20131010
    fbapi20131219    
    fbapi20140410
    fbapi20140116
    fbapi20150313
    fbapi20150629
    fbauth
    fbauth2
    fb-messenger-api20140430

If you're using FBSDKMessengerShareKit from versions older than the v4.6 release, also add

fb-messenger-platform-20150128
fb-messenger-platform-20150218
fb-messenger-platform-20150305

If you're using v4.6.0 of the SDK, you only need to add:

LSApplicationQueriesSchemes

        fbapi
        fb-messenger-api
        fbauth2
        fbshareextension

This will allow the FacebookSDK integration to properly identify installed Facebook apps to perform an app switch. If you are not recompiling with iOS SDK 9.0, your app is limited to 50 distinct schemes (calls to canOpenURL afterwards return NO).
