Xcode退出代码1 - 重复符号 [英] Xcode Exit Code 1 - Duplicate Symbol

问题描述

对不起，我知道这已经覆盖了所有地方，只是我无法解决这个问题以挽救我的生命。

Sorry I know this has been covered all over the place, only I can't fix this to save my life.

如果有人能够清楚地解释我的意思已经做了，我可以做些什么来解决这个问题，我将永远感激。

If someone could explain clearly what I might have done and what I might be able to do to fix this I would be forever grateful.

这是我的错误：

推荐答案

看起来您已经设置了两个目标，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，或者没有将此类编译为静态库的一部分，则不要直接在目标中使用该类（不要将该类添加到目标）。

It looks like you have two targets set up and your source is getting used in both. So, you create a static library with the sunnyHillsTL class that gets put into libcocoas2d libraries.a and then you are using the same object file as well. Either don't directly use the class in your target (don't add the class to the target) if you're using the library, or don't have this class be compiled as part of the static library.
