公历农历时间选择器

由于公司项目有个新需求,需要弹出公历和农历相互转化的时间选择器(类似万年历的时间弹框)。刚拿到需求的时候,在网上搜索好久,发现农历的时间选择器都少之甚少,又何况公历和农历的相互转化的时间选择器。遍寻许久终于发现一位大佬写的农历时间选择器。在此基础之上,整合公司的需求,终于完成了任务。下面分享给大家。

首先,要自定义一个公历时间选择器弹框,可以分为多种样式(年月日时,年月日,月日时等等)。

声明bool值_isNong判断是公历还是农历。只要点击农历按钮的时候,设置_isNong为yes,刷新pikerView即可。

关于农历,是参照大佬的(IDJChineseCalendar)封装改编的。当点击农历的时候,调用下面的方法

-(void)nongAction:(UIButton *)button{
    
    button.selected = !button.selected;
    _isNong = !_isNong;
    if (_isNong) {
        //显示农历数据
        _cal=[[IDJChineseCalendar alloc]initWithYearStart:MINYEAR end:MAXYEAR];
        [self _setYears];
        [self _setMonthsInYear:[_cal.year intValue]];
