如何在 ionic 3 中使用选项卡正确设置到我的主应用程序？

Question

大家好，我只是用这个命令开始一个项目"ionic start helloWorld tabs" 它生成选项卡式项目，然后我添加一个按钮以推送到新页面，这是我有一个按钮我想回到我的主应用程序，这是我如何编写新页面按钮

newpage.ts

  addItem(item: Item) {
    this.shopping.addItem(item).then(ref =>{
      this.navCtrl.setRoot('TabsPage', {key : ref.key});
    })
  }

保存项目后，我想返回到我的主要应用程序，我对我的 TabsPage 执行了 setRoot，但我显示了这个错误

invalid link: TabsPage

这是我的 tabs.ts

import { Component } from '@angular/core';

import { AboutPage } from '../about/about';
import { ContactPage } from '../contact/contact';
import { HomePage } from '../home/home';

@Component({
  templateUrl: 'tabs.html'
})
export class TabsPage {

  tab1Root = HomePage;
  tab2Root = AboutPage;
  tab3Root = ContactPage;

  constructor() {

  }
}

我错过了什么？我应该导航到 tabspage class 对吗？

UPDATE 在我用 @Yerkon 回答选项二更新我的代码后，我得到了这些错误：

Error: Uncaught (in promise): Error: Type TabsPage is part of the declarations of 2 modules: AppModule and TabsPageModule! Please consider moving TabsPage to a higher module that imports AppModule and TabsPageModule. You can also create a new NgModule that exports and includes TabsPage then import that NgModule in AppModule and TabsPageModule. Error: Type TabsPage is part of the declarations of 2 modules: AppModule and TabsPageModule! Please consider moving TabsPage to a higher module that imports AppModule and TabsPageModule. You can also create a new NgModule that exports and includes TabsPage then import that NgModule in AppModule and TabsPageModule.

它说我必须将我的 tabpagemodule 移高，这样做正常吗？或者我错过了什么？

Answer 1

invalid link: TabsPage

抛出此错误，因为 TabsPage 未在模块中注册。报名方式有两种：

如果页面急切加载:

app.module.ts:

@NgModule({
  declarations: [
    ConferenceApp,
    AboutPage,
    AccountPage,
    LoginPage,
    MapPage,
    PopoverPage,
    SchedulePage,
    ScheduleFilterPage,
    SessionDetailPage,
    SignupPage,
    SpeakerDetailPage,
    SpeakerListPage,
    TabsPage,
    TutorialPage,
    SupportPage
  ],
  imports: [
    BrowserModule,
    HttpModule,
    IonicModule.forRoot(ConferenceApp, {}, {
      links: [
        { component: TabsPage, name: 'TabsPage', segment: 'tabs-page' },
         ...
      ]
    }),
    IonicStorageModule.forRoot()
  ],
...

如果页面将延迟加载。在这里为您创建模块的每个页面。提示：使用 ionic CLI 无需手动创建 page/page.modules。只需运行：ionic g page TabsPage。结果应类似于：

tabs.module.ts:

import { NgModule } from '@angular/core';
import { TranslateModule } from '@ngx-translate/core';
import { IonicPageModule } from 'ionic-angular';

import { TabsPage } from './tabs';

@NgModule({
  declarations: [
    TabsPage,
  ],
  imports: [
    IonicPageModule.forChild(TabsPage),

  ],
  exports: [
    TabsPage
  ]
})
export class TabsPageModule { }

tabs.ts:

@IonicPage()
@Component({
  selector: 'page-tabs',
  templateUrl: 'tabs.html'
})
export class TabsPage {
  tab1Root: any = Tab1Root;
  tab2Root: any = Tab2Root;
  tab3Root: any = Tab3Root;
...
