问题
I have various touchEvents detection on a page on Safari Mobile (a controller, if you want to know...). They all work well indepedantly, but whenever I have a first touchpoint pressed, If I touch a new point, the events are triggered when I trigger a new one.
For example :
- I hold the stick with a finger. It's not moving
- I press a button, a touchStart event should be triggered but is not
- If I move the stick, the touchStart event is triggered
- If I let go of the button, the touchStart is triggered, but not the touchEnd
- If I move the stick (touchMove), the touchEnd is triggered
You understand how in my case it's a problem. I get buttons triggered with delay, or getting stuck until I move the stick, etc...
Is there a workaround ? thanks
