Answer 1

The method "application:openURL:sourceApplication:annotation:" is deprecated from iOS9. so now you can use like.

- (BOOL)application:(UIApplication *)app
        openURL:(NSURL *)url
        options:(NSDictionary *)options {
       // For Google sign in SDK
       if ([[GIDSignIn sharedInstance] handleURL:url
                               sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                                      annotation:options[UIApplicationOpenURLOptionsAnnotationKey]]) {
          return YES;
       // For Facebook SDK
       }else if ( [[FBSDKApplicationDelegate sharedInstance] application:app
                                                          openURL:url
                                                sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                                                       annotation:options[UIApplicationOpenURLOptionsAnnotationKey]]){
          return YES;
      //For Google plus SDK
      }else if ([GPPURLHandler handleURL:url
                       sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                              annotation:options[UIApplicationOpenURLOptionsAnnotationKey]]){
          return YES;
      }

     return NO;
}

Answer 2

We don't need to Explicitly need to check the URL, below code does it :-

- (BOOL)application: (UIApplication *)application openURL: (NSURL *)url sourceApplication: (NSString *)sourceApplication annotation: (id)annotation
{

    if ([GPPURLHandler handleURL:url sourceApplication:sourceApplication annotation:annotation]) {
        return YES;
    }else if([FBAppCall handleOpenURL:url sourceApplication:sourceApplication]){
        return YES;
    }

    return NO;
}

Answer 3

You can Try the following :

if ([[url absoluteString] rangeOfString:@"<Your Google Bundle ID>"].location ==            NSNotFound)
{
    // Call FBAppCall's handleOpenURL:sourceApplication to handle Facebook app responses
    BOOL wasHandled = [FBAppCall handleOpenURL:url sourceApplication:sourceApplication];
    // You can add your app-specific url handling code here if needed
    return wasHandled;
}
else
{
    return [GPPURLHandler handleURL:url
                  sourceApplication:sourceApplication
                         annotation:annotation];
}
return YES;

Call the above method in

(BOOL)application:(UIApplication *)application
          openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
       annotation:(id)annotation 

in your appDelegeate.m

Basically what this is going to do is examine the url prefix and then call the google+ method if url prefix is ur google+ bundle id , and if not , it'll call the fb method . Hope this helps

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
   sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation
{


   if( [GPPURLHandler handleURL:url
                  sourceApplication:sourceApplication
                     annotation:annotation])
   {
       return [GPPURLHandler handleURL:url
                     sourceApplication:sourceApplication
                            annotation:annotation];
   }
    else if([[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                sourceApplication:sourceApplication
                                                       annotation:annotation])
    {
        return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                              openURL:url
                                                    sourceApplication:sourceApplication
                                                           annotation:annotation];
    }
    return NO;
}

Answer 5

You can try this for a Swift 4.2 version:

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool 
{
    if (url.scheme?.hasPrefix("fb"))! {
        return SDKApplicationDelegate.shared.application(app, open: url, options: options)
    } 
    else
    {
        return GIDSignIn.sharedInstance().handle(url as URL?, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String,
                                                                 annotation: options[UIApplicationOpenURLOptionsKey.annotation])
    }           
}

Answer 6

You can just let either Google SDK or Facebook SDK attempt handling and if the SDK does not handle then allow the other SDK to try:

    @available(iOS 9.0, *)
private func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any])
    -> Bool {
        let handled: Bool = SDKApplicationDelegate.shared.application(application, open: url, options: options)

        if handled { return handled }

        return GIDSignIn.sharedInstance().handle(url,
                                                 sourceApplication:options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
                                                 annotation: [:])
}

//deprecated method iOS 8 and older
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
    let handled: Bool =  SDKApplicationDelegate.shared.application(application,
                                                                   open: url,
                                                                   sourceApplication: sourceApplication,
                                                                   annotation: annotation)

    if handled { return handled }

    return GIDSignIn.sharedInstance().handle(url,
                                             sourceApplication: sourceApplication,
                                             annotation: annotation)
}
