由于libWeANDSFLibrary.a（ASIReachability.o）​​导致的重复符号链接器错误 [英] duplicate symbol linker error due to libWeANDSFLibrary.a(ASIReachability.o)

问题描述

我正在使用 ASI （ ASIHTTPRequest ， ASIDownloadCache ，可达性等）请求。现在在我的项目中，我使用 reachability.h 和 .m file.I添加了一个第三方库和在那个图书馆里，我发现他们也在使用 ASI 库。
但据我所知，他们使用 ASIReachability 类而不是可达性。所以我也添加了 .h 文件。

I am using ASI (ASIHTTPRequest, ASIDownloadCache, Reachability etc) request. Now in my project, I am using reachability.h and .m file.I have added one third party library and in that library I came to know that they are also using ASI library. But as per my knowledge they are using ASIReachability class instead of Reachability. So I added that .h file as well.

我仍然收到链接器错误，其中说：

Still I am getting linker error which says :

请帮助我。感谢你。

推荐答案

您收到重复符号错误。所以你要搜索这个字符串 _kConnectionDown ， _kReachabilityChangedNotification ， _kLocalWiFiConnection ， _kInternetConnection ，并从文件中删除重复项。我想，您可以两次导入 Reachability 类，一个来自 libWeANDSFLibrary.a ，另一个来自 ASI 。检查一下。希望，帮助你。

You've receive duplicate symbol error. So you've to search this string _kConnectionDown, _kReachabilityChangedNotification, _kLocalWiFiConnection, _kInternetConnection, and remove duplication from files. I think, you may import Reachability class twice, one from libWeANDSFLibrary.a and another from ASI. Check this. Hope, help you.
