如何解决.../AppDelegate.h:13:1：“AppDelegate”类的接口定义重复错误

如何解决如何解决.../AppDelegate.h:13:1：“AppDelegate”类的接口定义重复错误

我正在按照以下说明将 Appslflyer 集成到我的 React-Native 应用程序中：https://support.appsflyer.com/hc/en-us/articles/360017822178#testing-ios-uninstalls

我想达到什么目的

我需要跟踪 iOS 卸载。他们使用静默推送通知，并要求我从上面的链接中复制粘贴一些代码。

我的问题是什么？

我已经完成了所有其他工作来设置 p12 证书并安装，但我一直无法将说明中的代码与我的应用程序中的现有代码合并。

我尝试了什么？

我不知道我在看什么代码，但我尝试重命名 AppDelegate 以解决 .h 文件中重复的接口名称错误并将其导入为 AppDelegate2 但之后我不知道如何实现接口。

我还努力将一些代码粘贴到现有实现中，但仍然无法构建，而且即使成功构建，我也不知道它是否有效。

具有 Objective-C 专业知识的人可以提供帮助吗？提前致谢。

我在代码片段中留下了 AppDelegate 的完整内容，以防您发现我可以粘贴新代码的位置，让生活更轻松。

在我按照说明操作之前，我的 AppDelegate.h 看起来像这样：

#import <Foundation/Foundation.h>
#import <EXUpdates/EXUpdatesAppController.h>
#import <React/RCTBridgeDelegate.h>
#import <UIKit/UIKit.h>

#import <UMCore/UMAppDelegateWrapper.h>
#import <AppsFlyerLib/AppsFlyerLib.h>

@interface AppDelegate : UMAppDelegateWrapper <RCTBridgeDelegate,EXUpdatesAppControllerDelegate>

@end

在我按照说明操作后，它看起来像：

    #import <Foundation/Foundation.h>
    #import <EXUpdates/EXUpdatesAppController.h>
    #import <React/RCTBridgeDelegate.h>
    #import <UIKit/UIKit.h>
    
    #import <UMCore/UMAppDelegateWrapper.h>
    #import <AppsFlyerLib/AppsFlyerLib.h>
    
    @interface AppDelegate : UMAppDelegateWrapper <RCTBridgeDelegate,EXUpdatesAppControllerDelegate>
    
    @end
    
    @interface AppDelegate2 : UIResponder <UIApplicationDelegate,AppsFlyerLibDelegate>
    @end

在粘贴新代码之前，我的 AppDelegate.m 看起来像这样：
