如何在特定页面上隐藏离子选项卡

Question

我想在我的离子Angular应用程序的2页中隐藏或除去离子选项卡，并将其保留在其他页面上。我试图动态更改rootPage，但是没有用。我正在使用Ionic 3.9.2和Angular5。如何仅在特定页面中隐藏这些选项卡？预先感谢！

app.component.ts

import { Component } from '@angular/core';
import { Platform } from 'ionic-angular';
import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';

import { TabsPage } from '../pages/tabs/tabs';
import { AuthService } from '../services/auth.service';

@Component({
  templateUrl: 'app.html'
})
export class MyApp {
  public rootPage: any = TabsPage;

  constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen, private authService: AuthService) {
    platform.ready().then(() => {
      statusBar.styleDefault();
      splashScreen.hide();
    });
  }
}
