Unity Calendar 日历功能

简介

工具已上传至SKFramework框架PackageManager中

框架开源地址：SKFramework

参数说明

• OnlyCurrentMonthDays：是否只显示当前月份的日期项；

参数为false时表示会填充当前月份1号之前的日期和当前月份最后一天之后的日期，这些日期不可交互。

• HistoryDaysInteractable：历史日期是否可以交互；

参数为false时表示当前日期之前的日期，即历史日期不可交互。（例如当前为1月11号，那么1月10号则不可以被选中）

事件说明

• OnEndEdit：DateTime参数类型事件，当结束编辑时执行（确认选择）
