有一个数组,数组中有13个元素,先将该数组进行分组,每3个元素为一组,分为若干组,最后用一个数组统一管理这些分组.(要动态创建数组).

<span style="white-space:pre">	</span>//创建数组
        NSMutableArray *array = [[NSMutableArray alloc] init];
        
        for (int i = 1; i < 14; i++) {
            [array addObject:[NSString stringWithFormat:@"Summer%d", i]];
        }
        //分组
        NSMutableArray *manageArr = [[NSMutableArray alloc] initWithCapacity:1];
        
        NSMutableArray *smallArr = nil;
        for (int i = 0; i < [array count]; i++) {
            if (i % 3 == 0) {
                smallArr = [[NSMutableArray alloc] initWithCapacity:1];
                [manageArr addObject:smallArr];
                [smallArr release];<span style="white-space:pre">	</span>//释放内存
            }
            [smallArr addObject:[array objectAtIndex:i]];
        }
        NSLog(@"%@", manageArr);
        [array release];<span style="white-space:pre">		</span>//释放内存
        [manageArr release];<span style="white-space:pre">		</span>//释放内存
