我已经用ionic start myApp blank
现在,我需要在项目中添加标签,在页面中创建文件夹标签,并在标签tabs.html
tabs.ts
中创建两个文件
在tabs.html
<ion-tabs>
<ion-tab [root]="homePage" tabTitle="Home" tabIcon="bulb" ></ion-tab>
<ion-tab [root]="reclamationsPage" tabTitle="Reclamations" tabIcon="settings"></ion-tab>
</ion-tabs>
在tabs.ts
中import { Component } from '@angular/core';
import { ReclamationsPage } from '../reclamations/reclamations';
import { HomePage } from '../home/home';
@Component({
selector: 'page-tabs',
templateUrl: 'tabs.html',
})
export class TabsPage {
reclamationsPage: ReclamationsPage;
homePage: HomePage;
}
在app.module.ts中 我已经添加
declarations: [
MyApp,
HomePage,
LoginPage,
ReclamationsPage,
TabsPage
],
imports: [
BrowserModule,
HttpModule,
HttpClientModule,
IonicModule.forRoot(MyApp)
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
HomePage,
LoginPage,
ReclamationsPage,
TabsPage
],
在app.component.ts中,我用rootPage:any
更改了rootPage:any = TabsPage;
但是当我执行我的代码离子服务时,我却注意到屏幕空白页中的图像
离子信息
