发送FCMnotification接收，未注册任何侦听器

Question

我正在ios React Native App中实现Firebase Push通知，

最初，我尝试使用无运气的react-native-firebase软件包，

然后我尝试使用react-native-fcm， 当我从Firebase控制台发送我的第一条消息时，按照react-native-fcm文档中的所有步骤进行操作后，我没有收到任何推送通知，但每次发送时“发送的FCMnotification收到但未注册任何侦听器” 消息如下img

我的安装过程如下

（1）创建firbase项目后，将googleservice-info.plist放置在项目文件夹中

（2）安装用于Firebase和Firebase /消息传递的容器

（3）npm install react-native-fcm --save

（4）react-native链接react-native-fcm

（5）在项目库中添加react-native-fcm .xcodeproj

（6）在构建阶段的“与库链接二进制文件”中添加libRNFIRmessaging.a

（7）在构建设置的标头搜索路径中添加$（SRCROOT）/../ node_modules / react-native-fcm / ios

（8）在appdelagate.h文件中添加以下代码

+ @import UserNotifications;
+
+ @interface AppDelegate : UIResponder <UIApplicationDelegate,UNUserNotificationCenterDelegate>
- @interface AppDelegate : UIResponder <UIApplicationDelegate>

（9）在Appdelegate.m文件中添加以下代码

+ #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
+
+ //You can skip this method if you don't want to use local notification
+ -(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];
+ }

（10）启用推送通知和远程通知功能

（11）步骤结束

我只想查看我的第一个推送通知

谢谢
