Ionic FirebasePush通知已收到但未在IOS上显示

Question

我正在通过Firebase云消息传递发送推送通知。在android上，它可以正常工作，但在ios上却不能。在Xcode控制台上，我看到已收到消息，但未显示任何内容。在iPhone上，当我进入应用程序设置时，找不到通知页面。 我已经设置了所有证书

这是xcode控制台

我的代码

async getToken(user) {
    let token;
    if (this.platform.is('android')) {
      token = await this.firebase.getToken();
    }

    if (this.platform.is('ios')) {
      token = await this.firebase.getToken();
      await this.firebase.grantPermission();
    }

    this.saveToken(token, user);
  }
