这是离子4解释

html。

   <ion-slides  [options]="slideOpts"  > 
          <ion-slide *ngFor="let item of cars">
            <img src="{{item}}" width="400px" height="250px">
          </ion-slide>
   </ion-slides>

.ts

import { Component, ViewChild } from '@angular/core';
import {IonSlides} from '@ionic/angular';
export class HomePage {
     @ViewChild(IonSlides) slides: IonSlides;
cars=[
"https://imgd.aeplcdn.com/1056x594/ec/79/85/9802/img/ol/Lamborghini-Aventador-Front-view-52648.jpg?v=201711021421&q=80",
  "https://imgd.aeplcdn.com/1056x594/ec/79/85/9802/img/ol/Lamborghini-Aventador-Right-Front-Three-Quarter-52645.jpg?v=201711021421&q=80",
  "https://imgd.aeplcdn.com/1056x594/ec/79/85/9802/img/ol/Lamborghini-Aventador-Right-Side-52646.jpg?v=201711021421&q=80",
  "https://imgd.aeplcdn.com/1056x594/ec/79/85/9802/img/ol/Lamborghini-Aventador-Left-Front-Three-Quarter-52647.jpg?v=201711021421&q=80",
  "https://imgd.aeplcdn.com/1056x594/ec/79/85/9802/img/ol/Lamborghini-Aventador-Front-view-52649.jpg?v=201711021421&q=80",
  "https://imgd.aeplcdn.com/1056x594/ec/79/85/9802/img/ol/Lamborghini-Aventador-Rear-view-52650.jpg?v=201711021421&q=80"
];


ngOnInit(){
  this.slides.startAutoplay().then(()=>{})}
}
 slideOpts = {
   speed: 10000
  };

您可以使用ViewChild抓住组件，然后可以在页面初始化中使用其方法。您链接的文档中提到了startAutoplay()。幻灯片选项使您可以设置过渡速度。如果您想要一个真正的解决方案每10秒翻转一次幻灯片，则可以编写一个异步方法，该方法每10秒更改幻灯片。如果您需要帮助，请注释。

您可以这样做，

.html

<ion-slides  #slid autoplay="5000" loop="true" speed="500" pager="true"  > 
          <ion-slide *ngFor="let item of cars">
            <img src="{{item}}" width="400px" height="250px">
          </ion-slide>
        </ion-slides>

.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { Platform } from 'ionic-angular';
import { TabsPage } from '../pages/tabs/tabs';


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

cars=[
"https://imgd.aeplcdn.com/1056x594/ec/79/85/9802/img/ol/Lamborghini-Aventador-Front-view-52648.jpg?v=201711021421&q=80",
  "https://imgd.aeplcdn.com/1056x594/ec/79/85/9802/img/ol/Lamborghini-Aventador-Right-Front-Three-Quarter-52645.jpg?v=201711021421&q=80",
  "https://imgd.aeplcdn.com/1056x594/ec/79/85/9802/img/ol/Lamborghini-Aventador-Right-Side-52646.jpg?v=201711021421&q=80",
  "https://imgd.aeplcdn.com/1056x594/ec/79/85/9802/img/ol/Lamborghini-Aventador-Left-Front-Three-Quarter-52647.jpg?v=201711021421&q=80",
  "https://imgd.aeplcdn.com/1056x594/ec/79/85/9802/img/ol/Lamborghini-Aventador-Front-view-52649.jpg?v=201711021421&q=80",
  "https://imgd.aeplcdn.com/1056x594/ec/79/85/9802/img/ol/Lamborghini-Aventador-Rear-view-52650.jpg?v=201711021421&q=80"
