iphone - 令人沮丧的 iPhone 构建错误

Question

我已经为此奋斗了几个小时，我已经厌倦了。我的项目使用调试模拟器构建、发布模拟器构建和调试设备构建可以正常构建，但由于某种原因，它无法使用发布设备构建进行构建。我有一个包含我的 cocos2d 代码的静态库，以及另一个包含我编写的游戏引擎的静态库。

因为游戏引擎包含类别，所以我必须使用 all_load 链接器标志来让它运行。如果没有这个标志，代码就可以正常构建。但是，当我尝试运行游戏时，我收到发送到实例异常的无法识别的选择器。

这是第一个构建错误:

这是第二个:

这是阻止我发布的唯一想法，所以我非常感谢您的帮助。

谢谢。

我遇到了类似的问题，我不小心包含(#import)实现文件而不是头文件

当编译器抛出 2 个目标文件包含重复符号的错误时，请检查您如何在 2 个实现文件中包含(#import)该重复符号的类。
