抱歉，我知道这个问题到处都是，只是我无法解决这个问题来挽救我的生命。

如果有人能清楚地解释我可能做了什么以及我可以做些什么来解决这个问题，我将永远感激不尽。

这是我的错误：

看起来您设置了两个目标，并且您的源在这两个目标中都被使用。所以，你创建了一个带有sunnhillsTL类的静态库，该类被放入libcocoas2d library.a中，然后你也使用了相同的目标文件。如果您正在使用库，请不要直接使用目标中的类（不要将类添加到目标中），或者不要将此类编译为静态库的一部分。

好像您的 «sunnyHillsTL» 类中有两个名为 «tileMap» 的实例变量...

从 Xcode 安装命令行工具。在 Xcode -> 首选项 -> 下载 -> 组件 -> 命令行工具
