Handling various URL schemes in iOS (Facebook and Instagram)

I'm not even sure how to identify the problem, but here it goes.

I have an application using the Facebook SDK for user login. I followed the Facebook authorization guide. I am not 100% sure how this works, but this part of my "AppDelegate.m" seems important.

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

    return [FBSession.activeSession handleOpenURL:url];
}

So far so good. Now I want to implement a similar login for instagram so that the user can access their photos. I run this example without problems ( https://github.com/crino/instagram-ios-sdk ). When I tried to import this into my project, I was stuck. Because the instagram project also has a function in AppDelegate (IGAppDelegate)

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

    return [self.instagram handleOpenURL:url];
}

( Facebook) facebook instagram (, "if" URL-).

PS: , facebook, URL-

fb4333597123414933:///# access_token = BAAGKI2vHLxUBANbDegkrdoc4GJWUZC2clqLAzxz8IxEBZBdEyjrD2oTaGZA0g2AbSGWgvEhONKM6xJWzLCALGUBguqUpor6kXu9ZBewusNZCUe6BOXYvX & expires_in = 5166254

instagram :

    - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
    {
        NSLog(@"url: %@", [url scheme]);

        BOOL callBack;
        // Facebook Call back checking.
        if ([[url scheme] isEqualToString:@"facebook_url_schema"])
        {
            callBack = [FBAppCall handleOpenURL:url sourceApplication:sourceApplication];
        }
        // Instagram call back checking.
        else if ([[url scheme] isEqualToString:@"instagram_url_schema"])
        {
            callBack = [self.instagram handleOpenURL:url];
        }
        return callBack;![enter image description here][1]

Swift: -

Google+, Facebook , OpenURL appDelegate.

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?,
    annotation: AnyObject?) -> Bool {

   println("URL : \(url)")
   if(url.scheme!.isEqual("fb1627825840806667")) {
        println("Facebook url scheme")

    return FBSDKApplicationDelegate.sharedInstance().application(
            application,
            openURL: url,
            sourceApplication: sourceApplication,
            annotation: annotation)

   } else {

        println("Google+ url scheme")

       return GIDSignIn.sharedInstance().handleURL(url, sourceApplication: sourceApplication, annotation: annotation)

   }
}

I think I found

[URL scheme] provides those specific URL schemes

Xcode - multiple URL schemes

For Swift 2.0

//MARK: FACEBOOK , GOOGLE CALLBACK URL METHOD
    //google-Firebase signin - IOS 8
    func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool
    {
        let googleDidHandle = GIDSignIn.sharedInstance().handleURL(url, sourceApplication: sourceApplication!, annotation: annotation)

        let facebookDidHandle = FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)

        return facebookDidHandle || googleDidHandle
    }

    //google-Firebase signin - IOS 9
    @available(iOS 9.0, *)
    func application(application: UIApplication,
                     openURL url: NSURL, options: [String: AnyObject]) -> Bool {

        let facebookDidHandle = FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as! String, annotation: options[UIApplicationOpenURLOptionsAnnotationKey])

        let googleDidHandle = GIDSignIn.sharedInstance().handleURL(url, sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as! String, annotation: options[UIApplicationOpenURLOptionsAnnotationKey])

        return facebookDidHandle || googleDidHandle
    }
