Micro-channel monitor applet page scrolling events

Some of the needs of users that slide up and down the screen to hide out certain requirements of the display area. Or a slide show content when the specified position.
Do listen for events four:
a, JS comes with:

//开始滚动
  onPageScroll (e) { 
  console.log('滚起来')
  },

This is not sensitive enough to listen, more BUg.
Second, the gesture events

<view class="wrapIndex" bindtouchstart="touchStart" bindtouchend="touchEnd"></view>
touchStart(e){
    //console.log('滚起来', e);
    this.setData({
      scrollStop: false
    })
  },
  touchEnd(e){
   // console.log('停下来', e);
    this.setData({
      scrollStop: true
    })
  },

The more sensitive easy to use. But it can not be arbitrary. At least one can be operated in full screen.
