MapContext.moveToLocation(Object object)

wxml:

<cover-view  id ='coverimg' class="flex-item">
          <cover-image src='../../images/return.png' bindtap='clickControl'></cover-image>
          </cover-view>

js:

clickControl:function(){
    this.mapCtx = wx.createMapContext('coverimg')
    this.mapCtx.moveToLocation()
  },
调用MapContext.moveToLocation()，点击图片无法跳转到初始位置
