swift - 方法 'application:didRegisterUserNotificationSettings:' 的重复声明

Question

我正在使用 React Native 处理“react-native-firebase”:“^5.5.6”和“react-native-push-notification”:“^3.1.9”，但我遇到了错误重复appDelegate.m 上方法“application:didRegisterUserNotificationSettings:”的声明

我尝试了通过网络找到的各种解决方案，如果我评论其中一种方法，则会收到错误“ native 模块不能为空”

- (void)application:(UIApplication *)application 
didRegisterUserNotificationSettings:(UIUserNotificationSettings 
*)notificationSettings {

  [[RNFirebaseMessaging instance] 
 didRegisterUserNotificationSettings:notificationSettings];
}

// Required to register for notifications
- (void)application:(UIApplication *)application 
didRegisterUserNotificationSettings:(UIUserNotificationSettings 
*)notificationSettings
{
[RCTPushNotificationManager 
didRegisterUserNotificationSettings:notificationSettings];
}

我的代码中需要这两种方法，没有任何错误。我也可以使用 if else 或其他解决方案，但由于我是这项技术的新手，因此任何帮助将不胜感激。提前致谢!

Answer 1

我不建议混合功能，但请尝试以下操作:

 - (void)application:(UIApplication *)application 
    didRegisterUserNotificationSettings:(UIUserNotificationSettings 
    *)notificationSettings {

      [[RNFirebaseMessaging instance] 
     didRegisterUserNotificationSettings:notificationSettings];

[RCTPushNotificationManager 
    didRegisterUserNotificationSettings:notificationSettings];

    }

因此，您可以使用相同的方法初始化两者。再说一遍，不知道为什么你需要两者，你应该尝试只保留一个。
