我知道这个问题之前已被多次询问过,但现在还没有人解决我的问题.我知道当您在项目中获得多个文件副本时会发生此错误.我试图清理构建,删除编译源中的任何LoginController.m文件,然后构建.很好 - 没有错误.当我在Complie资源中添加我的LoginController.m文件时,编译器再次给出了相同的错误.
接下来我尝试的是从Compile Sources中删除所有.m文件,成功清理和重建,并非常仔细地添加每个.m文件.再次提出同样的错误.我没有找到任何重复的文件,那么为什么会发生这种情况呢？
请有人指导我.非常感谢.

您的错误消息表明从LoginController.m和Navigator.m创建的二进制文件定义了您的LoginController类的实现.有时候这是因为共享头文件包含实现逻辑.检查Navigator.h/.m以获取对a的引用LoginController.
