* @tutorial https://www.uvui.cn/components/album.html
* @property {Array} urls 图片地址列表 Array<String>|Array<Object>形式
* @property {String} keyName 指定从数组的对象元素中读取哪个属性作为图片地址
* @property {String | Number} singleSize 单图时,图片长边的长度 (默认 180 )
* @property {String | Number} multipleSize 多图时,图片边长 (默认 70 )
* @property {String | Number} space 多图时,图片水平和垂直之间的间隔 (默认 6 )
* @property {String} singleMode 单图时,图片缩放裁剪的模式 (默认 'scaleToFill'
* @property {String} multipleMode 多图时,图片缩放裁剪的模式 (默认 'aspectFill'
* @property {String | Number} maxCount 取消按钮的提示文字 (默认 9 )
* @property {Boolean} previewFullImage 是否可以预览图片 (默认 true )
* @property {String | Number} rowCount 每行展示图片数量,如设置,singleSize和multipleSize将会无效 (默认 3
* @property {Boolean} showMore 超出maxCount时是否显示查看更多的提示 (默认 true )
