1. 獲取當(dāng)前時間 YY年 MM 月dd日 ?hh小時 mm分鐘 ss秒 自由搭配獲取
NSDate *currentDate = [NSDate date];//獲取當(dāng)前時間，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.判斷NSDate是星期幾 (今天星期幾)
#pragma mark -->獲取今天星期幾
- (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.獲取當(dāng)月的總天數(shù)
NSCalendar *calendar = [NSCalendar currentCalendar];
NSRange range = [calendar rangeOfUnit:NSDayCalendarUnit inUnit:NSMonthCalendarUnit forDate:[NSDate date]];
NSUInteger numberOfDaysInMonth = range.length;
NSLog(@"%lu", (unsigned long)numberOfDaysInMonth);
4.. 判斷NSDate的農(nóng)歷
-(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", @"臘月", 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;
}
