when I use iframe in ion-content, the ion-content scroll is not working

Use overflow-scroll to enable scrolling

<ion-view view-title="title">
    <ion-content overflow-scroll="true">
         <iframe src="{{link}}"></iframe>
    </ion-content>
</ion-view>

It's a bug on ios. I have resolved this problem. Refer to the following
