App delegate method:

Answer 1

You need to add this method if your app is running on iOS9 or above.

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options {
return [[FBSDKApplicationDelegate sharedInstance] application:app
                                                  openURL:url
                                        sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                                               annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];

}

In case you need a Swift version:

@available(iOS 9.0, *)
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    return SDKApplicationDelegate.shared.application(app,
                                                     open: url,
                                                     sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String,
                                                     annotation: options[UIApplicationOpenURLOptionsKey.annotation] as Any)
}
