Objective-C代码没有释放内存!

Question

我正在努力学习Objective-C.我几乎完成了一个练习,但它没有释放内存:

这就是我所拥有的:

void PrintPolygonInfo() {
    NSLog(@"--------------------");
    NSLog(@" PRINT POLYGON INFO");
    NSLog(@"--------------------");
    NSMutableArray *array = [[NSMutableArray alloc] init];
    PolygonShape *p1 = [[PolygonShape alloc] initWithNumberOfSides:4 minimumNumberOfSides:3 maximumNumberOfSides:7];
    PolygonShape *p2 = [[PolygonShape alloc] initWithNumberOfSides:6 minimumNumberOfSides:5 maximumNumberOfSides:9];
    PolygonShape *p3 = [[PolygonShape alloc] initWithNumberOfSides:12 minimumNumberOfSides:9 maximumNumberOfSides:12];
    [array addObject:p1];
    [array addObject:p2];
    [array addObject:p3];
    // Log the descriptions
    for (id shape in array) {
        NSLog(@"%@", shape);
    }
    // Test the constraints
    for (PolygonShape *shape in array) {
        [shape setNumberOfSides:10];
    }
    [p1 release];
    [p2 release];
    [p3 release];
}

这是dealloc():

- (void) dealloc {
    NSLog(@"Deallocated!!!");
    [super dealloc];
}

这就是结果:

2009-11-19 06:58:17.030 Assignment 1B[5441:a0f] --------------------

2009-11-19 06:58:17.034 Assignment 1B[5441:a0f] Invalid number of sides: 10 is greater than the maximum of 7 allowed
2009-11-19 06:58:17.035 Assignment 1B[5441:a0f] Invalid number of sides: 10 is greater than the maximum of 9 allowed

如您所见,它不会打印'Deallocated !!!'消息:

任何人都可以告诉我,我做错了吗？

提前致谢

该数组保留它包含的对象.只有从数组中删除对象或释放数组后,才能释放对象.
