I was using an iframe inside my Ionic app but it was not scrolling. To fix this issue use the following HTML markup and CSS:

<ion-content scroll="true" overflow-scroll="true" class="iframe-wrapper">
   <iframe data-tap-disabled="true" src="{{iframeURL}}"></iframe>
</ion-content>

.iframe-wrapper iframe{
  width: 100%;
  height: 100%;
}
