Question

对不起，我知道这已经被覆盖了，只有我无法解决这个问题才能挽救我的生命。

如果有人能够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：

Answer 1

看起来您已设置了两个目标，并且您的源都在两者中使用。因此，您使用 sunnyHillsTL 类创建一个静态库，该类可以放入 libcocoas2d libraries.a ，然后您也使用相同的目标文件。如果您正在使用该库，则不要直接在目标中使用该类（不要将该类添加到目标中），或者不要将此类编译为静态库的一部分。

Answer 2

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