Question

我在尝试编译时遇到重复的符号错误。错误信息是：

duplicate symbol _OBJC_IVAR_$_SideBarCell._profilePic in:
    /Users/kex/Library/Developer/Xcode/DerivedData/myProject-aoizqcetllkwnxgbqvmjyrxmxrbw/Build/Intermediates/myProject.build/Debug-iphoneos/myProject.build/Objects-normal/arm64/SideBarCell.o

ld: 3 duplicate symbols for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我根本不熟悉这种类型的错误。我的项目中的引用是否被混淆了？非常感谢对此提出一些建议!!!

Answer 1

潜在原因 - 我：

更有可能的是，您的一个（.m或.h）文件中有多个文件在您的项目中同名。

潜在原因-II：

您可以添加file.m代替file.h

编译时重复符号错误，第一次看到这个错误
