在iOS中集成Google和Facebook登录 – AppDelegate openURL

我正在尝试将Facebook和谷歌登录集成到我的应用程序中,但遇到问题：两者都需要将以下内容添加到Appdelegate中的openURL方法中：

return [GIDSignIn sharedInstance] handleURL:url
                           sourceApplication:sourceApplication
                                         annotation:annotation]];

return [FBSDKApplicationDelegate sharedInstance] application:application
                                                       openURL:url
                                             sourceApplication:sourceApplication
                                                    annotation:annotation
         ]]

无论如何都要让这两者正确地协同工作.我在网上看了一下,但答案很模糊,未能提供很好的解释

解

添加了以下功能(从iOS 9开始)：

return [[GIDSignIn sharedInstance] handleURL:url sourceApplication:sourceApplication annotation:annotation] || [[FBSDKApplicationDelegate sharedInstance] application:application openURL:url sourceApplication:sourceApplication annotation:annotation ];

解决方法

使用以下代码……

- (BOOL)application:(UIApplication *)applicationopenURL:(NSURL *)url
      sourceApplication:(Nsstring *)sourceApplicationannotation:(id)annotation
    {
      if ([FBAppCall handleOpenURL:url sourceApplication:sourceApplication])
        return [FBSDKApplicationDelegate sharedInstance] application:application
                                                       openURL:url
                                             sourceApplication:sourceApplication
                                                    annotation:annotation
         ]];
      else

       return [GIDSignIn sharedInstance] handleURL:url
                           sourceApplication:sourceApplication
                                         annotation:annotation]];
    }

另一个答案..

- (BOOL)application:(UIApplication *)applicationopenURL:(NSURL *)url
  sourceApplication:(Nsstring *)sourceApplicationannotation:(id)annotation
{

     Nsstring *stringURL = [ url absoluteString];
    if([stringURL containsstring:@"fb"])
    {


    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                sourceApplication:sourceApplication
                                                       annotation:annotation];
    }
    else
    {
        return [GPPURLHandler handleURL:url
                      sourceApplication:sourceApplication
                             annotation:annotation];

    }
}
