Question

我尝试在以下指南中添加phonegap-plugin-push插件后，我的Ionic应用程序停留在启动画面上：https://ionicframework.com/docs/native/push/

我尝试删除和添加平台，删除和添加phonegap-plugin-push插件，结果是一致的 - 只要将push插件添加到我的项目中，应用程序在启动屏幕时无故障地无故障。

以下是app.component.ts上的代码：

  constructor(
    public events: Events,
    public userData: UserData,
    public menu: MenuController,
    public platform: Platform,
    public parseData: ParseData,
    public storage: Storage,
    public splashScreen: SplashScreen,
    private iab: InAppBrowser,
    private push: Push
  ) {
    this.platform.ready().then(() => {
      console.log("platform ready called");
      this.nav.setRoot(TabsPage);
      this.menu.enable(true);
      this.splashScreen.hide();
      console.log("splash screen hide called");
    });
  }

  handlePush(){
    // to check if we have permission
    this.push.hasPermission()
      .then((res: any) => {

        if (res.isEnabled) {
          console.log('We have permission to send push notifications');
        } else {
          console.log('We do not have permission to send push notifications');
        }

      });

    // to initialize push notifications

    const options: PushOptions = {
       android: {
           senderID: '12345679'
       },
       ios: {
           alert: 'true',
           badge: true,
           sound: 'false'
       },
       windows: {}
    };

    const pushObject: PushObject = this.push.init(options);

    pushObject.on('notification').subscribe((notification: any) => console.log('Received a notification', notification));

    pushObject.on('registration').subscribe((registration: any) => console.log('Device registered', registration));

    pushObject.on('error').subscribe(error => console.error('Error with Push plugin', error));
  }

不再调用整个构造函数方法！

这是运行应用程序时的日志输出：

Answer 1

我看到你正在使用wkwebview插件。由于这个插件，我在启动画面遇到了冻结。删除它对我有帮助。希望它也能帮到你。

Answer 2

我发现了问题。我在ionic native documentation之后安装了@ ionic-native / push插件 - 示例代码中的语法导致了问题。只要我切换到v1.x guide中的示例代码，问题就会消失。
