爱华网需求：1.定义普通僵尸类：实例变量：僵尸总血量、僵尸每次失血量。方法：初始化方法(总血量)、被打击失血、死亡。
2.定义路障僵尸类：实例变量：僵尸总血量、僵尸每次失血量，道具，弱点。方法：初始化方法(总血量)、被打击失血、失去装备、死亡。
3.定义铁桶僵尸类：实例变量：僵尸总血量、僵尸每次失血量，道具，弱点。方法：初始化方法(总血量)、被打击失血、失去装备、死亡。
4.在main.m中创建普通僵尸对象，设置总血量50，每次失血量为3，没有道具。
5.在main.m中创建路障僵尸对象，设置总血量80，每次失血量为2，设置道具为路障。
6.在main.m中创建铁桶僵尸对象，设置总血量120，每次失血量为1，设置道具为铁桶。

[roadhitted];
IronDrumZombie *iron = [[IronDrumZombie alloc] initWithHP:120lostHP:1 tool:@"铁桶" weakness:@"头部"];
[ironhitted];
return0;
}
定义普通僵尸、路障僵尸和铁桶僵尸三个类
