FCM 推送通知在使用离子电容器的 IOS 中不起作用

Question

使用 CAPACITOR 和 IONIC 在 Android 上一切正常，但在 IOS 上出现以下错误：

APNS device token not set before retrieving FCM Token for Sender ID 'mySenderId'. Notifications to this FCM Token will not be delivered over APNS.Be sure to re-retrieve the FCM token once the APNS device token is set.

Latest Dependencies:

  @capacitor/cli: 3.2.2
  @capacitor/core: 3.2.2
  @capacitor/android: 3.2.2
  @capacitor/ios: 3.2.2

Installed Dependencies:

  @capacitor/cli: 3.2.2
  @capacitor/core: 3.2.2
  @capacitor/android: 3.2.2
  @capacitor/ios: 3.2.2

我可以在我的 Xcode 日志中看到 FCM 令牌，但通知不起作用。

您似乎缺少 APNS 设置并将其与 FCM 连接。只需按照这个很棒的教程： https://devdactic.com/push-notifications-ionic-capacitor/

Answer 2

解决方法是先注册APNS token再注册FCM token。

 PushNotifications.requestPermissions().then((permission) => {
    if (permission.receive == "granted") {
      // Register with Apple / Google to receive push via APNS/FCM
      if(Capacitor.getPlatform() == 'ios'){
        PushNotifications.register().then((res)=>{
          console.log('From Regisiter Promise', res)
        })
        PushNotifications.addListener('registration', (token: Token)=>{            
          FCM.getToken().then((result) => {
            this.remoteToken = result.token;
          }).catch((err) => console.log('i am Error' , err));
        })
      }else{
        FCM.getToken().then((result) => {
          this.remoteToken = result.token;
        }).catch((err) => console.log('i am Error' , err));
      }
    } else {
      // No permission for push granted
      alert('No Permission for Notifications!')
    }
  });

插件的最新版本：

PushNotifications.requestPermissions().then((permission) => {
        if (permission.receive == "granted") {

          PushNotifications.addListener('registration', async ({ value }) => {
            let token = value // Push token for Android
          
            // Get FCM token instead the APN one returned by Capacitor
            if (Capacitor.getPlatform() === 'ios') {
              const { token: fcm_token } = await FCM.getToken()
              token = fcm_token
            }
            // Work with FCM_TOKEN
            
            console.log(token);
          })
        } else {
          // No permission for push granted
          alert('No Permission for Notifications!')
        }
      });
