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、Reachability 等)请求.现在在我的项目中，我使用 reachability.h 和 .m 文件.我添加了一个第三方库，在那个库中我知道他们也在使用ASI 库.但据我所知，他们使用的是 ASIReachability 类而不是 Reachability.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，内容为:

Still I am getting linker error which says :

请帮帮我.谢谢你.

推荐答案

您收到重复符号错误.因此，您必须搜索此字符串 _kConnectionDown、_kReachabilityChangedNotification、_kLocalWiFiConnection、_kInternetConnection，并从文件中删除重复项.我认为，您可以两次导入 Reachability 类，一个来自 libWeANDSFLibrary.a，另一个来自 ASI.检查这个.希望能帮到你.

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.
