in cccV1.1.0 touch. getPreviousLocation c++bind error: bSimulator : Error: js_cocos2dx_Touch_getLocationInView : Invalid Native Object

at a: “let curTouchPosition = touch.getLocationInView()” (assets/xxxxxx)
Simulator : ScriptingCore::callFunctionName error:__errorHandler wasn’t found!
Is it’s my fault?Or the engine?
I tested on my end and the API works fine.
Could you post your code in context?
eventNode.on(cc.Node.EventType.TOUCH_MOVE, (event) => {
if(_this.intercept()) {
return;
}
//单点触摸，移动
if(_touches.length == 1) {
let touch = _touches[0];
let curTouchPosition = touch.getLocationInView();
let preTouchPosition = touch.getPreviousLocationInView();
eventNode.x = eventNode.x + curTouchPosition.x - preTouchPosition.x;
eventNode.y = eventNode.y - curTouchPosition.y + preTouchPosition.y;
I simply wan’t move a texture,and it work fine in a web browser,but can not work in simulator…
It also can not work in ios’s simulator,some error log like:

I’ve tested these two API and they work fine.
Could you check your _touches array and see if it has correct value?
yes，yet,I tested _touches array and in touch_start I can get call _touches[0].getdelta() and other method,but when i want call these methods from touch_move ,something error happended,the log say inviald native object.I think if just my way is not in.but it can do well in web browser,i just can not understand it.
