Ios8 什么是iOS 8.0+；NSCalendarUnits？

我注意到所有的

NSCalendarUnits

（例如，

NSDayCalendarUnit

）从iOS 8.0开始就被正式弃用了。 替换内容是什么？

它们被替换为（只需查看SDK）：

typedef NS_选项（NSInteger、NSCalendarUnit）{
NSCalendarUnitEra=kCFCalendarUnitEra，
NSCalendarUnitYear=kCFCalendarUnitYear，
NSCalendarUnitMonth=kCFCalendarUnitMonth，
NSCalendarUnitDay=kCFCalendarUnitDay，
NSCalendarUnitHour=kCFCalendarUnitHour，
NSCalendarUnitMinute=kCFCalendarUnitMinute，
NSCalendarUnitSecond=kCFCalendarUnitSecond，
NSCalendarUnitWeekday=kCFCalendarUnitWeekday，
NSCalendarUnitWeekdayOrdinal=kCFCalendarUnitWeekdayOrdinal，
NSCalendarUnitQuarter NS_ENUM_可用（10_6，4_0）=kCFCalendarUnitQuarter，
NSCalendarUnitWeekOfMonth NS_ENUM_可用（10_7，5_0）=kCFCalendarUnitWeekOfMonth，
NSCalendarUnitWeekOfYear NS_ENUM_可用（10_7，5_0）=kCFCalendarUnitWeekOfYear，
NSCalendarUnitYearForWeekOfYear NS_ENUM_可用（10_7，5_0）=kCFCalendarUnitYearForWeekOfYear，
NSCalendarUnit纳秒NS_ENUM_可用（10_7，5_0）=（1谢谢。请注意。
