1. 获取当前时间 YY年 MM 月dd日 hh小时 mm分钟 ss秒 自由搭配获取
NSDate *currentDate = [NSDate date];//获取当前时间，日期
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"YYYY/MM/dd hh:mm:ss SS"];
NSString *dateString = [dateFormatter stringFromDate:currentDate];
NSLog(@"dateString:%@",dateString);
2.判断NSDate是星期几 (今天星期几)
#pragma mark -->获取今天星期几
- (NSString*)weekdayStringFromDate:(NSDate*)inputDate {
NSArray *weekday = [NSArray arrayWithObjects: [NSNull null], @"周日", @"周一", @"周二", @"周三", @"周四", @"周五", @"周六", nil];
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
NSTimeZone *timeZone = [[NSTimeZone alloc] initWithName:@"Asia/Shanghai"];
[calendar setTimeZone: timeZone];
NSCalendarUnit calendarUnit = NSCalendarUnitWeekday;
NSDateComponents *theComponents = [calendar components:calendarUnit fromDate:inputDate];
return [weekday objectAtIndex:theComponents.weekday];
}
3.获取当月的总天数
NSCalendar *calendar = [NSCalendar currentCalendar];
NSRange range = [calendar rangeOfUnit:NSDayCalendarUnit inUnit:NSMonthCalendarUnit forDate:[NSDate date]];
NSUInteger numberOfDaysInMonth = range.length;
NSLog(@"%lu", (unsigned long)numberOfDaysInMonth);
4.. 判断NSDate的农历
-(NSString*)getChineseCalendarWithDate:(NSDate *)date{
NSArray *chineseYears = [NSArray arrayWithObjects:
@"甲子", @"乙丑", @"丙寅", @"丁卯", @"戊辰", @"己巳", @"庚午", @"辛未", @"壬申", @"癸酉",
@"甲戌", @"乙亥", @"丙子", @"丁丑", @"戊寅", @"己卯", @"庚辰", @"辛己", @"壬午", @"癸未",
@"甲申", @"乙酉", @"丙戌", @"丁亥", @"戊子", @"己丑", @"庚寅", @"辛卯", @"壬辰", @"癸巳",
@"甲午", @"乙未", @"丙申", @"丁酉", @"戊戌", @"己亥", @"庚子", @"辛丑", @"壬寅", @"癸丑",
@"甲辰", @"乙巳", @"丙午", @"丁未", @"戊申", @"己酉", @"庚戌", @"辛亥", @"壬子", @"癸丑",
@"甲寅", @"乙卯", @"丙辰", @"丁巳", @"戊午", @"己未", @"庚申", @"辛酉", @"壬戌", @"癸亥", nil nil];
NSArray *chineseMonths=[NSArray arrayWithObjects:
@"正月", @"二月", @"三月", @"四月", @"五月", @"六月", @"七月", @"八月",
@"九月", @"十月", @"冬月", @"腊月", nil nil];
NSArray *chineseDays=[NSArray arrayWithObjects:
@"初一", @"初二", @"初三", @"初四", @"初五", @"初六", @"初七", @"初八", @"初九", @"初十",
@"十一", @"十二", @"十三", @"十四", @"十五", @"十六", @"十七", @"十八", @"十九", @"二十",
@"廿一", @"廿二", @"廿三", @"廿四", @"廿五", @"廿六", @"廿七", @"廿八", @"廿九", @"三十", nil nil];
NSCalendar *localeCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierChinese];
unsigned unitFlags = NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay;
NSDateComponents *localeComp = [localeCalendar components:unitFlags fromDate:date];
NSLog(@"%zd_%zd_%zd",localeComp.year,localeComp.month,localeComp.day);
NSString *y_str = [chineseYears objectAtIndex:localeComp.year-1];
NSString *m_str = [chineseMonths objectAtIndex:localeComp.month-1];
NSString *d_str = [chineseDays objectAtIndex:localeComp.day-1];
NSString *chineseCal_str =[NSString stringWithFormat: @"%@_%@_%@",y_str,m_str,d_str];
return chineseCal_str;
}
