Question

根据react-native PushNotificationIOS文档（未在插件中使用），我在AppDelegate中具有以下代码，对didReceiveRemoteNotification进行了一些细微调整，以便它可以处理前台和后台的通知，但是，我无法告诉是从哪里处理的，我的处理程序需要知道，因为它做的是不同的事情。

有什么想法可以获取这些信息吗？

// Required to register for notifications
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
 {
  [RCTPushNotificationManager didRegisterUserNotificationSettings:notificationSettings];
 }
 // Required for the register event.
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
 {
  [RCTPushNotificationManager didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
 }
 // Required for the notification event. You must call the completion handler after handling the remote notification.
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
 {
  [RCTPushNotificationManager didReceiveRemoteNotification:userInfo];
  completionHandler(UIBackgroundFetchResultNewData);
 }
 // Required for the registrationError event.
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
 {
  [RCTPushNotificationManager didFailToRegisterForRemoteNotificationsWithError:error];
 }
 // Required for the localNotification event.
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
 {
  [RCTPushNotificationManager didReceiveLocalNotification:notification];
 }

您想在JS端还是本机端知道。如果在本地，请参考此Detect if the application in background or foreground in swift。在JS端，您可以使用react-native AppState API。 https://facebook.github.io/react-native/docs/appstate
