黑马程序员 oc随记 写一个手动内存释放

真要命，半天找不到内存泄漏的原因，结果发现是自己把一个类的字母少写了，郁闷。

    @autoreleasepool {
        buyer *b=[buyer new];
        goods *g=[goods new];
        selfer *s=[selfer new];
        b.name=@"买家";
        b.age=19 ;
        b.high=183;
        s.name=@"卖家";
        s.age=22;
        s.high=155;
        g.name=@"巧克力";
        g.kg=1.23;
        g.price=5;
        
        [s setGoods:g];
        [g release];
        [s release];
        [b release];
        
    }
    return 0;
