React Native集成fbsdk-next报错：'FBSDKApplicationDelegate'未声明标识符

在构建React Native应用时，安装并配置react-native-fbsdk-next包后，反复出现以下编译报错：

error: use of undeclared identifier 'FBSDKApplicationDelegate' if ([[FBSDKApplicationDelegate sharedInstance] application:app openURL:url options:options]) { ^

尝试过相关解决方案但问题依旧，以下是当前的配置代码：

相关配置代码 #

AppDelegate.mm文件 #

#import "AppDelegate.h"

#import <React/RCTBundleURLProvider.h>
#import <AuthenticationServices/AuthenticationServices.h>
#import <SafariServices/SafariServices.h>
#import <FBSDKCoreKit/FBSDKCoreKit-Swift.h>
#import <React/RCTLinkingManager.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)app
            openURL:(NSURL *)url
            options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
{
  if ([[FBSDKApplicationDelegate sharedInstance] application:app openURL:url options:options]) {
    return YES;
  }

  if ([RCTLinkingManager application:app openURL:url options:options]) {
    return YES;
  }
  
  return NO;
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  self.moduleName = @"AppName";
  // 可在下方字典中添加自定义初始属性，会传递给React Native使用的ViewController
  self.initialProps = @{};

  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

- (NSURL *)sourceURLForBridge:(RCTBridge *)bridge
{
  return [self getBundleURL];
}

- (NSURL *)getBundleURL
{
#if DEBUG
  return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index"];
#else
  return [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
#endif
}

@end

Info.plist配置 #

<key>CFBundleURLTypes</key>
    <array>
        <dict>
            <key>CFBundleURLSchemes</key>
            <array>
                <string>fb<my-id></string>
            </array>
        </dict>
    </array>
    <key>CFBundleVersion</key>
    <string>$(CURRENT_PROJECT_VERSION)</string>
    <key>FacebookAppID</key>
    <string><my-id></string>
    <key>FacebookClientToken</key>
    <string><my-token></string>
    <key>FacebookDisplayName</key>
    <string><app-name></string>
    <key>LSApplicationQueriesSchemes</key>
    <array>
        <string>fbapi</string>
        <string>fb-messenger-share-api</string>
    </array>

Podfile配置 #

手动链接的Pod依赖：

pod 'react-native-fbsdk-next', :path => '../node_modules/react-native-fbsdk-next'

尝试过的额外配置：

installer.aggregate_targets.first.user_project.native_targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings['LIBRARY_SEARCH_PATHS'] = ['$(inherited)', '$(SDKROOT)/usr/lib/swift']
      end
    end

解决方案尝试 #

1. 替换头文件导入：将#import <FBSDKCoreKit/FBSDKCoreKit-Swift.h>替换为Objective-C原生头文件#import <FBSDKCoreKit/FBSDKCoreKit.h>，FBSDKApplicationDelegate是Objective-C类，Swift头文件可能未正确暴露该类。
2. 添加SDK初始化代码：在didFinishLaunchingWithOptions方法中加入Facebook SDK初始化逻辑，确保SDK被正确加载：

   - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
   {
     // 初始化Facebook SDK
     [[FBSDKApplicationDelegate sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];
     
     self.moduleName = @"AppName";
     self.initialProps = @{};
   
     return [super application:application didFinishLaunchingWithOptions:launchOptions];
   }
   

3. 更新Pod依赖并清理缓存：执行以下命令更新Facebook SDK到兼容版本，同时清理Pods缓存：

   pod deintegrate && pod update FBSDKCoreKit && pod install
   

4. 启用Swift混编支持：如果项目未启用Swift，在Xcode中新建一个空的Swift文件（命名为Dummy.swift即可），Xcode会自动生成桥接文件，确保Swift和Objective-C代码能正常交互。
5. 检查Build Settings配置：打开Xcode项目的Build Settings，确认FRAMEWORK_SEARCH_PATHS包含$(inherited)，保证Facebook SDK框架能被正确检索到。
