ios - 点击推送通知后打开一个页面 Ionic 2 iOS

Question

最近，我一直在我的应用程序中添加推送通知功能。我正在使用在此 link 上找到的 FCN 插件我使用 Ionic 2 框架进行开发。通知已发送，但当我点击它时，它只会打开应用程序的主页，而不是我需要的内页。

我用过这段代码

declare var FCMPlugin;
@Component({
  templateUrl: 'app.html'
})
export class MyApp {
  rootPage:any = HomePage;
  horoscopePage:any = HoroscopeHomePage;
  @ViewChild(Nav) nav: Nav;

   **********************

    FCMPlugin.onNotification(function(data){
      if(data.wasTapped){
        //Notification was received on device tray and tapped by the user.
        if(data.topic =="horoskopi" && data.type=="list"){

        console.log( JSON.stringify(data) );

        this.nav.push(this.horoscopePage);

        }

      }else{

        if(data.topic =="horoskopi" && data.type=="list"){

        console.log( JSON.stringify(data) );

        this.nav.push(this.horoscopePage);
        }
      }
  });
  });

这行代码 this.nav.push(this.horoscopePage); 没有做任何事情

当我改用 NavController 时，它给我这个错误:

MyApp_Host.html:1 ERROR Error: No provider for NavController!
    at injectionError (core.es5.js:1231)

Answer 1

您可以将 public navCtrl: NavController 添加到 constructor 中，然后将代码更改为

this.navCtrl.push(this.horoscopePage);
