试试这可能适用于您的应用程序：

settings the options autoplay to true

slideOptsOne = {
 initialSlide: 0,
 slidesPerView: 1,
 autoplay:true
};

page.html

<ion-slides [options]="slideOptsOne">
 <ion-slide *`ngFor`="let item of topStories">
   <ion-card (click)=" this.newsService.onGoToTopStoryPage(item)">
     <ion-card-content>
       <ion-img [src]="item.image"></ion-img>
       <h2> <b>{{item.title}} </b></h2>
       <h4>{{item.summary}}</h4>
     </ion-card-content>
   </ion-card>
 </ion-slide>
</ion-slides>

在 page.ts 文件的选项中添加您的配置。让我知道它是否有效。
