没有设置itemColor

这个问题是概率性出现的，所以无法提供出现的条件

产生此现象的关键代码片段：

    wx.showActionSheet({
      itemList: ['公交线路', '驾车导航', '使用本机的其它APP导航(推荐)'],
      success: res => {
        let tab_index = res.tapIndex
        if (tab_index == 0)
          this.get_navigate_data('transit')
        else if (tab_index == 1)
          this.get_navigate_data('driving')
        else if (tab_index == 2) 
          this.navigate_by_map_app()
      }
    })
