ios 如何单独排序只含有date的数组

- (void)sortCurrentReservationsByDateWithCurrentListArray:(NSArray *)dateArray {

    if (dateArray) {

        NSArray *dateArray = @[@"Fri Jun 24 2016", @"Fri Apr 08 2016", @"Mon Apr 08 2016", @"Mon Jun 14 2016"];

        //format the date

        NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

        [formatter setDateFormat:@"c MM dd yyyy"];

        

        NSMutableArray *tempArray = [NSMutableArray array];

        [dateArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL * stop) {

            DDLogInfoWithTag(LOG_TAG_LISA,@"before sort by date array is %@", obj);

            NSDate *date = [formatter dateFromString:obj];

            if (date) {

                [tempArray addObject:date];

            }

        }];

        

        //sort the array of dates NSOrderedDescending

        [tempArray sortUsingComparator:^NSComparisonResult(NSDate *date1, NSDate *date2) {

            // return date2 compare date1 for descending. Or reverse the call for ascending.

            return [date2 compare:date1];

        }];

        

        DDLogInfoWithTag(LOG_TAG_LISA, @"after sort by date array is %@", tempArray);

        NSLog(@"%@", tempArray);

        

    }

    

}
