得到NSDate的月，日或年份？

Question

说我有以下内容：

NSDate *today = [NSDate date];

我如何只获得该月的获取整数值？天？还是一年？

Answer 1

你想要这个NSDateCOmponenets

具体是：

- (NSDateComponents *)components:(NSUInteger)unitFlags  fromDate:(NSDate *)date

Answer 2

或者你可以使用NSDate类：

NSDate *date = [NSDate date];
    int month = [[date descriptionWithCalendarFormat:@"%m" timeZone:nil locale:nil] intValue];
    int day = [[date descriptionWithCalendarFormat:@"%d" timeZone:nil locale:nil] intValue];
    int year = [[date descriptionWithCalendarFormat:@"%Y" timeZone:nil locale:nil] intValue];

    NSLog(@"Today: %i-%i-%i", year, month, day);

希望它有效， ief2
