错误：使用未声明的标识符“FBSDKApplicationDelegate”

Question

我安装了

react-native-fbsdk-next

。 遵循配置步骤。 想要在 iOS 上构建应用程序（像往常一样）。我收到了

error: use of undeclared identifier 'FBSDKApplicationDelegate' and the app won't build.

错误：

我的AppDelegate.mm：

#import "AppDelegate.h"
#import <React/RCTBundleURLProvider.h>
#import <react-native-splash-screen/RNSplashScreen.h>
#import <FBSDKCoreKit/FBSDKCoreKit.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  self.moduleName = @"AppName";
  self.initialProps = @{};

  bool didFinish=[super application:application didFinishLaunchingWithOptions:launchOptions];
  [RNSplashScreen show];
  [[FBSDKApplicationDelegate sharedInstance]application:application
    didFinishLaunchingWithOptions:launchOptions];
  return didFinish;
}

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

- (BOOL)concurrentRootEnabled
{
  return true;
}


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

@end

规范package.json和Podfile.lock：

"react": "18.2.0",
"react-native": "0.71.2",

Info.plist配置：（ID当然是数字）

<dict>
...
    <key>CFBundleURLTypes</key>
    <array>
      <dict>
        <key>CFBundleURLSchemes</key>
        <array>
          <string>fbID</string>

      <string>fbauth2</string>

    </array>
</dict>

我尝试过切换

#import <FBSDKCoreKit/FBSDKCoreKit.h>

进入

#import <FBSDKCoreKit/FBSDKCoreKit-Switch.h>

应用程序构建，但我无法打开应用程序 - 崩溃。 我还尝试通过删除 Pod、删除派生数据以及卸载模拟器中的应用程序来修复它。

#导入

添加这行代码修复此错误。

Answer 2

问题在于，react-native-fbsdk-next 包的部分内容包含 Swift 代码。将此代码添加到 post_install pod 可以解决问题。

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

Answer 3

更换

#import <FBSDKCoreKit/FBSDKCoreKit.h>

到

#import <FBSDKCoreKit/FBSDKCoreKit-Swift.h>
