Ionic-framework: RC1 swipe-back on iOS doesn't disable vertical scroll

[levymetal]

Short description of the problem:

If you swipe-back on iOS, the content on the current page can still be scrolled. This can be reproduced on both the device and emulator. Video: https://youtu.be/WTS_-KXSW74

What behavior are you expecting?

Once a swipe-back is initiated, vertical scrolling should be disabled.

Steps to reproduce:

1. Clone the ionic 2 tutorial app
2. Emulate or run on device
3. Swipe-back while moving finger up and down, the view can still be scrolled.

Which Ionic Version?

2.0.0-rc.1

@levymetal we are aware of this issue, here's the thing, we can't find yet a good way to disable scrolling

[levymetal]

Ah, I see. Is there a way to disable swipe back then? I've tried <ion-nav [root]="rootPage" swipeBackEnabled="false"></ion-nav>, and putting swipeBackEnabled = false pretty much everywhere but nothing seems to work.

@levymetal Yes, have a look here:
http://ionicframework.com/docs/v2/api/config/Config/

I'm concidering wring my own "swipe to go back" using the swipe gesture event and manually poping the page from the navstack. It won't be as nice at the native "real time swipe" of course, but better than nothing, and better that the current ionic implementation. Might be worth a try!

@danielcrk-cn Awesome, that worked, cheers for that! I like your idea as a stop-gap until this issue is resolved. Let us know if you end up doing it.

This is not fixed in RC3 (at least not in my app).

I see some logging in XCode console regarding scrolling, but I'm still able to scroll the leaving view in the middle of a swipe back.

@biesbjerg it need hybrid assistance, are you using the latest ionic WK plugin?

Any updates regarding issue? I have not yet found a method to disable the scrolling during swipe back.
