react-native - 如果您也安装了 FBSDK，React Native、iOS、Google 登录将重定向到 google.com

Question

如果您安装 Google 登录https://github.com/devfd/react-native-google-signin，那么您可以按照 Google 的设置说明进行操作。到了这一步，就可以做好登录了。

之后，您还要安装 FBSDK，https://github.com/facebook/react-native-fbsdk，然后按照 Facebook 的设置说明进行操作。在这一步，您将被重定向到 google.com。

Answer 1

打开您AppDelegate.m现有的代码：

- (BOOL)application:(UIApplication *)application 
            openURL:(NSURL *)url 
            options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {

  BOOL handled = [[FBSDKApplicationDelegate sharedInstance] application:application
    openURL:url
    sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
    annotation:options[UIApplicationOpenURLOptionsAnnotationKey]
  ];
  // Add any custom logic here.
  return handled;
}

将其修改为：

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
            options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {

  BOOL handled = [[FBSDKApplicationDelegate sharedInstance] application:application
                                                                openURL:url
                                                      sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                                                             annotation:options[UIApplicationOpenURLOptionsAnnotationKey]
                  ]
  || [RNGoogleSignin application:application
                                                    openURL:url
                                          sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                                                 annotation:options[UIApplicationOpenURLOptionsAnnotationKey]
      ];
  // Add any custom logic here.
  return handled;
}
