在这里我很鄙视百度,尼玛 竟然每一个我想要的结果。。。最后还是用google弄到的。日前又需要自己以后慢慢研究
1. 获取当前月份有多少天
NSCalendar *calendar = [NSCalendarcurrentCalendar];
NSRange range = [calendarrangeOfUnit:NSDayCalendarUnitinUnit:NSMonthCalendarUnitforDate:[NSDatedate]];
NSUInteger numberOfDaysInMonth = range.length;
numberOfDaysInMonth 即为当月的天数。更多用法查看NSCalendar, NSDateComponents帮助文档
2. 获取当前年份和月份和天数
NSCalendar *calendar = [NSCalendar currentCalendar];
unsigned unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit;
NSDateComponents *components = [calendar components:unitFlags fromDate:[NSDate date]];
NSInteger iCurYear = [components year]; //当前的年份
NSInteger iCurMonth = [components month]; //当前的月份
NSInteger iCurDay = [components day]; // 当前的号数
