Trying my luck here…
For some reason $ionicActionSheet no longer works on iOS 8.4 in an existing app, while it works as expected on iOS 9.
The problem is that $ionicActionSheet.show will show only a backdrop. If you tap on it (anywhere) the backdrop will disappear.
The funny thing is that I am not able to reproduce this on an app made from scratch / minimal app.
Using Ionic 1.1.0. Android too works as expected.
Anyone else encountering this?
