Question

好吧，当我运行应用程序时，该应用程序在没有任何警告或错误的情况下运行，但是当我尝试对其进行测试时，我遇到了一堆错误，如下所示:

 ld: symbol(s) not found for architecture x86_64
 clang: error: linker command failed with exit code 1 (use -v to see invocation)

我该如何解决这个问题？

Answer 1

转到

TargetSettings -> Build Phases -> Compile Sources -> add your .m file (in which you are getting error) ->Build and Run

还有一种可能性是检查您是否正确添加了所有框架？
