获取当前时间、年份、月份、日期等
- (void)getCurrentDate {
//获得时间对象
//NSDate *date = [NSDate date];
//// 获得系统的时区
//NSTimeZone *zone = [NSTimeZone systemTimeZone];
//// 以秒为单位返回当前时间与系统格林尼治时间的差
//NSTimeInterval time = [zone secondsFromGMTForDate:date];
//// 然后把差的时间加上,就是当前系统准确的时间
//NSDate *nowDate = [date dateByAddingTimeInterval:time];
//NSLog(@"now date is: %@", nowDate);
// 获取当前时间
NSDate *now = [NSDate date];
// NSLog(@"now date is: %@", now);
NSCalendar *calendar = [NSCalendar currentCalendar];
unsigned unitFlags = NSCalendarUnitYear | NSCalendarUnitMonth |NSCalendarUnitDay | NSCalendarUnitHour |NSCalendarUnitMinute | NSCalendarUnitSecond | NSCalendarUnitWeekday;
NSDateComponents *dateComponent = [calendar components:unitFlags fromDate:now];
NSLog(@"dateComponent is :%@", dateComponent);
NSInteger year = [dateComponent year];
NSInteger month = [dateComponent month];
NSInteger day = [dateComponent day];
NSInteger hour = [dateComponent hour];
NSInteger minute = [dateComponent minute];
NSInteger second = [dateComponent second];
