只獲得NSDate的月份，日期或年份？

Question

說我有以下幾點：

NSDate *today = [NSDate date]; 

如何爲一個月我只是在獲取整數值？天？或一年？

Answer 1

或者你可以只使用的NSDate類：

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);
