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。

点击农历按钮转化为农历

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]];
[self _setDaysInMonth:_cal.month year:[_cal.year intValue]];
}
[self getNowDate:self.scrollToDate animated:YES];
[self.datePicker reloadAllComponents];
}
