你可 以在Xcode项目中的cocos2d/Support组找到CCArray的类文件。cocos2d引擎内 部使用了CCArray。它和苹果官方的NSMutableArray类似,但是运行效率更高。 CCArray类实现了NSArray和NSMutableArray的子集,并且添加一些从NSArray初 始化到CCArray的新方法。CCArray通过将数组中的最后一个对象(nil)赋值给删 除的位置,实现了fastRemoveObject和fastRemoveObjectAtIndex两个方法。避 免了复制部份数组的内存。这让删除数组中的元素变的更快,不过这也意味着 CCArray中的对象会改变位置。如果你的程序依赖于指定的对象排列次序,你就 不应该使用fastRemoveObject这类方法。在列表4-9中,你可以看到CCArray的 类引用 – 它没有实现所有的NSArray和NSMutableArray方法:
