Question

嘿所以我正在使用标签启动器应用程序的修改版本，我的应用程序刚开始在滚动和点击方面没有响应。只有选项卡按钮才能切换页面。没有其他的。我发布下面的代码，有没有人有任何想法？

app.html

<ion-nav [root]="rootPage" swipeBackEnabled="false"></ion-nav>

app.component.ts

＆＃13;

import { Component, ViewChild } from '@angular/core';
import { Platform, Nav } from 'ionic-angular';
import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';

import { TabsPage } from '../pages/tabs/tabs';
import { HomePage } from '../pages/home/home';
import { AboutPage } from '../pages/about/about';
import { ContactPage } from '../pages/contact/contact';
import { VendorPage } from '../pages/vendor/vendor';
import { TipsPage } from '../pages/tips/tips';

@Component({
  templateUrl: 'app.html'
})
export class MyApp {
  @ViewChild(Nav) nav: Nav;

  rootPage:any = TabsPage;

  pages: Array<{title: string, component: any}>;

  constructor(public platform: Platform,
              public statusBar: StatusBar,
              public splashScreen: SplashScreen) {
    this.initializeApp();

    // used for an example of ngFor and navigation
    this.pages = [
      { title: 'Home', component: HomePage },
      { title: 'About', component: AboutPage },
      { title: 'Contact', component: ContactPage },
      { title: 'Vendors', component: VendorPage },
      { title: 'Tips', component: TipsPage }
    ];
  }

  initializeApp() {
    this.platform.ready().then(() => {
      // Okay, so the platform is ready and our plugins are available. Here you can do any higher level native things you might need.
      this.statusBar.styleDefault();
      this.splashScreen.hide();
    });
  }

  openPage(page) {
    // Reset the content nav to have just this page
    // we wouldn't want the back button to show in this scenario
    this.nav.setRoot(page.component);
  }

}

不确定我的app.module.ts中的某些内容是否会导致此问题？
