本文演示如何在代码中获取当前时间，并使用NSCalendar解析为年、月、日、小时、分钟、秒等详细日期组件。

//获取当前时间

NSDate
 *now = [NSDate date];

NSLog(@"now
 date is: %@",
 now);

NSCalendar
 *calendar = [NSCalendar currentCalendar];

NSUInteger
 unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit | 

NSDayCalendarUnit
 | NSHourCalendarUnit | NSMinuteCalendarUnit | 

NSSecondCalendarUnit;

NSDateComponents
 *dateComponent = [calendar components:unitFlags fromDate:now];

intyear
 = [dateComponent year];

intmonth
 = [dateComponent month];

intday
 = [dateComponent day];

inthour
 = [dateComponent hour];

intminute
 = [dateComponent minute];

intsecond
 = [dateComponent second];

NSLog(@"year
 is: %d",
 year);

NSLog(@"month
 is: %d",
 month);

NSLog(@"day
 is: %d",
 day);

NSLog(@"hour
 is: %d",
 hour);

NSLog(@"minute
 is: %d",
 minute);

NSLog(@"second
 is: %d",
 second);
