具有推送通知功能的React本机应用程序在启动时崩溃

Question

我正在尝试使用react native fcm接收推送通知。正如文件所述，我正在安装并实施以下所有步骤

a） 安装react-native fcmnpm安装react-native fcm--save

b）使用react-本机链接react-nate-fcm链接库

c） 下载谷歌服务信息。plist文件，从firebase控制台将其放入/ios/my project目录中

d）使用Cocoapods 1. cd ios安装Firebase消息传递

e）编辑AppServer. h

@import UserNotifications;
@interface AppDelegate : UIResponder <UIApplicationDelegate,UNUserNotificationCenterDelegate>
/*@interface AppDelegate : UIResponder <UIApplicationDelegate>*/

f） 编辑AppDelegate。m

#import "RNFIRMessaging.h"
//...

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  //...
  [FIRApp configure];
  [[UNUserNotificationCenter currentNotificationCenter] setDelegate:self];

   return YES;
}


-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
{
  [RNFIRMessaging willPresentNotification:notification withCompletionHandler:completionHandler];
}

#if defined(__IPHONE_11_0)
-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler
{
  [RNFIRMessaging didReceiveNotificationResponse:response withCompletionHandler:completionHandler];
}
#else
-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler
{
  [RNFIRMessaging didReceiveNotificationResponse:response withCompletionHandler:completionHandler];
}
#endif

-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification 
{
  [RNFIRMessaging didReceiveLocalNotification:notification];
}

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(nonnull NSDictionary *)userInfo fetchCompletionHandler:(nonnull void (^)(UIBackgroundFetchResult))completionHandler
{
  [RNFIRMessaging didReceiveRemoteNotification:userInfo fetchCompletionHandler:completionHandler];
}

g） 启用功能

1. 推送通知
2. 背景模式

然后我将我的应用程序归档在ipa中，并尝试在设备上启动它。加载屏幕出现后应用程序崩溃。请向我解释一下，我的错在哪里？

注：没有人。js文件不会从create react native app命令更改。

请仔细阅读笔记，他解释了为什么你应该切换到react native firebase
