setBackgroundMessageHandler在android上工作，但在本机react中不在IOS上工作

Question

后台通知在Android上接收，但在本机react的IOS上不接收

index.js

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

这是在注册组件之前调用的，正如某些Github问题中提到的那样。

这个问题是在迁移到react native firebase v6之后出现的。

软件包版本：-

我通过REST API发送的通知有效负载是：-

apns: {
payload: {
aps: {
"content-available": "true"
}
},
headers: {
"apns-priority": "10",
}
}

我使用了一个外部设备进行测试，启用了xcode中的所有后台模式和推送通知，也从apple dev帐户启用了推送通知。当前xcode版本为12.4

任何帮助都将不胜感激。非常感谢。

将apns标头中可用内容的值替换为1，而不是"true"：

"content-available":1
