anchorScroll() with overflow-scroll=true does not work in iOS

ionic-v1
1

I am trying to use what is recommended elsewhere to use anchorScroll().

<ion-content overflow-scroll="true">
</ion-content>

Then, in the controller:

$location.hash("example-id");
$anchorScroll();

When run in iOS, it doesn’t work, and you cannot even scroll.

Help?
