在Xcode中编译应用程序时出现无法解析的链接器错误

Question

我一直在研究一个应用程序一段时间，它一直给我在iPhone上编译时遇到麻烦。最近，即使在模拟器上也停止编译。我浏览过堆栈溢出和其他网站的答案，但我似乎无法找到任何解决问题的东西。以下是我收到的错误。

我已经恢复整个应用程序的早期版本，看看是否解决了这个问题，但它似乎没有任何区别。我仍然遇到同样的错误。

任何人都可以帮忙吗？

ld: library not found for -lPods 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

Answer 1

进一步审查和摆弄后，并审查通过@damian引用类似的问题后，似乎解决方案是这样的：

我用

target :App do 
… 
end 

target :AppTests do 
… 
end 

分离的Podfile应用和测试目标

这分别产生了两个新产品libPods-App.a和libPods-AppTests.a，它们使以前的产品libPods.a过时。我必须从两个目标的Build Phases配置中的链接二进制库与库部分删除此产品。

感谢大家的输入！

尝试删除您的派生数据文件夹，重新启动Xcode并再次运行项目。转至Window -> Projects并导航至您的项目。应该提到你的派生数据文件夹。按Delete，重新启动Xcode并尝试再次构建。看看是否会再次将它踢回高速档。
