ion-slides with multiple touches can stuck on iOS

tujlaky commented 5 years ago

I'm submitting a ... (check one with "x") [ x ] bug report [ ] feature request

Current behavior:

If ion-slides touched with a second finger after a touch started on iOS the slide got stuck because ion-slide not supports multiple touch events.

Expected behavior:

It should return to the starting point when the second gesture was not long enough.

Steps to reproduce:

With sliding the left thumb to left slide a little with the right thumb on the second slide.

I don't know if it's related but I had an issue when touching the screen with two fingers. Here is my issue on iOS:

slide with one finger => everything is fine
swipe anywhere on the screen with two fingers. It doesn't do anything. That's ok, but then if you try to slide normally with one finger, the event "ionSlideDidChange" is no longer triggered.

I found a workaround though, now I use the event ionSlideTransitionEnd which works all the time. Hope it helps.
