PanResponder.onPanResponderMove not responding for pinch

[weixingsun]

Hello, @Stoffern

I cannot get event that more than 2 touches in my app using RN0.29

PanResponder.create({
onPanResponderMove: (evt, gestureState){
if(evt.nativeEvent.touches.length<2) //move
//if(evt.nativeEvent.changedTouches.length<2) //also move?
else //pinch, this condition is never called.
}
...
})
//Is PanResponder changing the API ?
thanks very much!

@weixingsun please provide more details, ios, android, code +
It should all work on RN 0.29

@weixingsun did you solve this?

[weixingsun]

@Stoffern sorry for late, I cannot make it works on both Android 6.0.1/iOS 9.3.3 device with my RN.29, which is very annoying. I have tried to clean node_modules folder and re-install with no luck.
When doing some debugging, in PanResponder.onPanResponderMove function, evt.nativeEvent.touches never greater than 1.
Could you please share a working example code for pinching with PanResponder, I am very new to this function, thank you so much.

Here is my code, thanks a lot:

@weixingsun this is not related to this repo as you are creating your own.
This would normally be a react-native question.

The answer is that you are using:
evt.nativeEvent.touches only main finger.
you should use:
evt.nativeEvent.changedTouches as this will register changes on the touch, when you use two fingers.

closing this as it is not related to the repo

@Stoffern are you sure this solution really works? move event is not triggered for me whenever the panResponder has 2 fingers

It didn't work for me either. Any news on this yet?
