* @tutorial https://www.uviewui.com/components/picker.html
* @property {Object} params 需要显示的参数,见官网说明
* @property {String} mode 模式选择region-地区类型time-时间类型默认time
* @property {String Number} start-year 可选的开始年份mode=time时有效默认1950
* @property {String Number} end-year 可选的结束年份mode=time时有效默认2050
* @property {Boolean} safe-area-inset-bottom 是否开启底部安全区适配默认false
* @property {Boolean} show-time-tag 时间模式时,是否显示后面的年月日中文提示
* @property {String} cancel-color 取消按钮的颜色(默认#606266
* @property {String} confirm-color 确认按钮的颜色(默认#2979ff
* @property {String} default-time 默认选中的时间mode=time时有效
* @property {String} confirm-text 确认按钮的文字
* @property {String} cancel-text 取消按钮的文字
* @property {String} default-region 默认选中的地区中文形式mode=region时有效
* @property {String} default-code 默认选中的地区编号形式mode=region时有效
* @property {Boolean} mask-close-able 是否允许通过点击遮罩关闭Picker默认true
* @property {String Number} z-index 弹出时的z-index值默认1075
* @property {Array} default-selector 数组形式其中每一项表示选择了range对应项中的第几个
* @property {Array} range 自定义选择的数据mode=selector或mode=multiSelector时有效
* @property {String} range-key 当range参数的元素为对象时指定Object中的哪个key的值作为选择器显示内容
* @event {Function} confirm 点击确定按钮,返回当前选择的值
* @event {Function} cancel 点击取消按钮,返回当前选择的值
