令人沮丧的iPhone构建错误

我现在已经打了几个小时了,我已经厌倦了.我的项目可以通过调试模拟器构建,发布模拟器构建和调试设备构建来构建,但由于某种原因,它不会使用发布设备构建构建.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,所以我不得不使用all_load链接器标志来运行它.没有这个标志,代码构建正常.但是,当我尝试运行游戏时,我收到一个无法识别的选择器发送到实例异常.

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,所以我非常感谢你的帮助.

谢谢.

解决方法

我遇到了类似的问题,我不小心包含了(#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,请检查您在2个实现文件中如何包含(#import)该重复符号的类.
