在iOS（Facebook和Instagram）中处理不同的URL方案

Question

我甚至不确定如何定义问题，但在这里它。

我有一个使用Facebook SDK进行用户登录的应用程序。我按照Facebook授权教程。我不是100％确定它是如何工作的但是我的“AppDelegate.m”中的这一部分似乎很重要。

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

    return [FBSession.activeSession handleOpenURL:url];
}

到现在为止还挺好。现在我想为instagram实现类似的登录，以便用户可以访问他们的照片。我运行这个例子没有问题（https://github.com/crino/instagram-ios-sdk）。当我试图将它导入我的项目时，我陷入困境。因为在instagram项目中AppDelegate中还有一个函数（IGAppDelegate）

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

    return [self.instagram handleOpenURL:url];
}

现在我不能使用这个功能（因为它是Facebook的副本）有没有办法将这两个功能结合到facebook和instagram（对于不同的URL可能有“if”）。或者我输了

PS：我注意到当我打电话给我的facebook登录应用程序时，网址就像是

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

在Instagram中它就像：

igfd725621c5e44198a5b8ad3f7a0ffa09：//authorize#access_token=354172840.fd72562.bf6b3611632d4d00b6cef660ea9d9b6f

    - (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]
    }

斯威夫特： -

在swift app中同时使用Google+和Facebook的示例，它们都需要appDelegate中的OpenURL方法。

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)

   }
}

对于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
    }

我想我找到了

[url scheme]给出了那些特定的URL方案

Xcode - multiple URL Schemes
