FCM通知在ios中不起作用 [英] FCM Notification is not working in ios

问题描述

我正在我的app.i中集成FCM通知和云消息，其遵循firebase文档中提到的完全相同的步骤。即使我尝试过FCM提供的示例代码。它只是抛出一些警告，如< FIRInstanceID / WARNING>无法获取APNS令牌错误域= com.firebase.iid代码= 1001操作无法完成。< FIRMessaging / WARNING> FIRMessaging注册尚未准备好使用身份验证凭据。

I am integrating FCM notification and cloud messaging in my app.i have followed exactly same steps mentioned in firebase doc. Even I have tried with sample code given by FCM. it is just throwing some warnings as <FIRInstanceID/WARNING> Failed to fetch APNS token Error Domain=com.firebase.iid Code=1001 "The operation couldn’t be completed. and <FIRMessaging/WARNING> FIRMessaging registration is not ready with auth credentials.

任何人都可以帮我解决这个问题。我正在谷歌上搜索一周，但我没有得到任何帮助。我在Appdelegate.m编写的代码是

Can anyone help me to sort out it. i am googling since one week regarding it but nothing helpful i got. My code written in Appdelegate.m is

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Register for remote notifications
    if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_7_1) {

    NSString *refreshedToken = [[FIRInstanceID instanceID] token];
    NSLog(@"InstanceID token: %@", refreshedToken);

    // Connect to FCM since connection may have failed when attempted before having a token.

希望尽快得到回复。
提前致谢！

Hope to get a reply soon. Thanks in advance!

推荐答案

看来您需要将优先级设置为高，如果您希望在应用程序处于后台时显示通知：

It appears that you need to have the "priority" set to "high" if you want the notification to get displayed while the app is in the background:

当应用关闭时，Firebase IOS推送通知无效
