在将Facebook SDK导入AppDelegate.m文件中需要帮助

Question

目前，我正在尝试根据Facebook将以下内容添加到我的appdelegate.m中：

• （BOOL）应用程序：（UIApplication *）应用程序 didFinishLaunchingWithOptions：（NSDictionary *）launchOptions {

  [[FBSDKApplicationDelegate sharedInstance]应用程序：应用程序 didFinishLaunchingWithOptions：launchOptions];

  //在此处添加任何自定义逻辑。 返回是； }

• （BOOL）应用程序：（UIApplication *）应用程序 openURL：（NSURL *）url     选项：（NSDictionary *）选项{

  BOOL处理= [[FBSDKApplicationDelegate sharedInstance]应用程序：应用程序     openURL：url         sourceApplication：options [UIApplicationOpenURLOptionsSourceApplicationKey]         注解：选项[UIApplicationOpenURLOptionsAnnotationKey]         ];

  //在此处添加任何自定义逻辑。 退货处理 }

---

我当前的文件如下：

• （BOOL）应用程序：（UIApplication *）应用程序didFinishLaunchingWithOptions：（NSDictionary *）launchOptions {

  [[NSUserDefaults standardUserDefaults] setBool：NO forKey：@“ back”]; [[NSUserDefaults standardUserDefaults] synchronize];

---

当我插入代码时，它看起来像这样：

• （BOOL）应用程序：（UIApplication *）应用程序 didFinishLaunchingWithOptions：（NSDictionary *）launchOptions {

  [[FBSDKApplicationDelegate sharedInstance]应用程序：应用程序                          didFinishLaunchingWithOptions：launchOptions];

  //在此处添加任何自定义逻辑。 返回是； }

• （BOOL）应用程序：（UIApplication *）应用程序         openURL：（NSURL *）url         选项：（NSDictionary *）选项{

  BOOL处理= [[FBSDKApplicationDelegate sharedInstance]应用程序：应用程序                                                               openURL：url                                                     sourceApplication：options [UIApplicationOpenURLOptionsSourceApplicationKey]                                                            注解：选项[UIApplicationOpenURLOptionsAnnotationKey]                 ];

  //在此处添加任何自定义逻辑。 已处理退货；

  [[NSUserDefaults standardUserDefaults] setBool：NO forKey：@“ back”]; [[NSUserDefaults standardUserDefaults] synchronize];

Xcode告诉我 [[NSUserDefaults standardUserDefaults] setBool：NO forKey：@“ back”]; 代码将永远不会执行。

请帮助

我的appDelegate.m看起来像theis，我没有您的错误

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

  // Firebase configurations
  [FIRApp configure];

  // Facebook SDK
  [[FBSDKApplicationDelegate sharedInstance] application:application
                           didFinishLaunchingWithOptions:launchOptions];

  NSURL *jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
  [ReactNativeNavigation bootstrap:jsCodeLocation launchOptions:launchOptions];

  return YES;
}



// FACEBOOK SDK
- (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;
}
