nvue文件app运行环境下，手势事件返回的事件信息有缺陷
运行附件demo.nvue文件，触发手势事件，得到如下结果(缺少changedTouches内容，不能判断手势偏移值)：
{
"type": "touchmove",
"timeStamp": 1566985757006,
"target": {
"id": "",
"dataset": {},
"offsetLeft": 0,
"offsetTop": 0
},
"currentTarget": {
"id": "",
"dataset": {},
"offsetLeft": 0,
"offsetTop": 0
},
"detail": {},
"touches": [],
"changedTouches": []
}
运行附件demo.vue文件，触发手势事件，得到如下结果：
