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）

using UnityEngine;

public class Example : MonoBehaviour
{
    public void OnSelectedTime(DateTime dateTime)
    {
        Debug.Log(string.Format(">>>> {0}", dateTime));
    }
}
