iphone - Xcode 退出代码 1 - 重复符号

Question

抱歉，我知道这个问题已经被广泛报道，只是我无法解决这个问题以挽救我的生命。

如果有人可以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，我将永远感激不已。

这是我的错误:

Answer 1

看起来您设置了两个目标，并且您的源代码正在这两个目标中使用。因此，您使用 sunnyHillsTL 类创建一个静态库，并将其放入 libcocoas2dlibraries.a 中，然后您也使用相同的目标文件。如果您正在使用该库，请不要直接在目标中使用该类(不要将该类添加到目标中)，或者不要将该类编译为静态库的一部分。
