setBackgroundMessageHandler 正在 android 上工作，但不在本机反应中的 IOS 上

问题描述

在 Android 上收到后台通知，但在 React Native 上的 IOS 上不收到。

index.js

-ln

这是在注册组件之前调用的，如某些 Github 问题中所述。

迁移到 react native firebase v6 后出现这个问题。

软件包版本：-

 messaging().setBackgroundMessageHandler(async (message)=>{
  console.log(message)
});

我通过 REST API 发送的通知负载是：-

#import <React/RCTBridgeDelegate.h>
#import <UIKit/UIKit.h>
#import "RNAppAuthAuthorizationFlowManager.h"

@interface AppDelegate : UIResponder <UIApplicationDelegate,RCTBridgeDelegate,RNAppAuthAuthorizationFlowManager>

@property (nonatomic,strong) UIWindow *window;
@property(nonatomic,weak)id<RNAppAuthAuthorizationFlowManagerDelegate>authorizationFlowManagerDelegate;

@end

我使用了外部设备进行测试，在 xcode 和 Apple 开发帐户中启用了所有后台模式和推送通知。 当前的 xcode 版本是 apns: { payload: { aps: { "content-available": "true" } },headers: { "apns-priority": "10",} }

任何帮助将不胜感激。谢谢！

解决方法

将 apns 标头中 content-available 的值替换为 1 而不是“true”：

"content-available":1
