* @property {Boolean} overlay 是否显示遮罩 (默认 true
* @property {String} mode 弹出方向(默认 'bottom'
* @property {String | Number} duration 动画时长单位ms (默认 300
* @property {String | Number} overlayDuration 遮罩层动画时长单位ms (默认 350
* @property {Boolean} closeable 是否显示关闭图标(默认 false
* @property {Object | String} overlayStyle 自定义遮罩的样式
* @property {String | Number} overlayOpacity 遮罩透明度0-1之间默认 0.5
* @property {Boolean} closeOnClickOverlay 点击遮罩是否关闭弹窗 (默认 true
* @property {String | Number} zIndex 层级 (默认 10075
* @property {Boolean} safeAreaInsetBottom 是否为iPhoneX留出底部安全距离 (默认 true
* @property {Boolean} safeAreaInsetTop 是否留出顶部安全距离(状态栏高度) (默认 false
* @property {String} closeIconPos 自定义关闭图标位置(默认 'top-right'
* @property {String | Number} round 圆角值(默认 0
