      let _this = this;
      let moveStartY = e.changedTouches[0].pageY;
      _this.moveStartY = moveStartY;
},
 handleScrollEnd:function(e){
       let _this = this;
       let moveEndY =  e.changedTouches[0].pageY;
       
       //下滑
      if(moveEndY - _this.moveStartY > 200){
            uni.startPullDownRefresh();
           ...
      }

   	 //上划
      if( _this.moveStartY - moveEndY > 200 ){
            ...
     }
}
