请教库冲突的导致的 duplicate symbol 链接错误

怀疑是使用的SDK和本身项目使用同一个库造成冲突.
错误消息:
duplicate symbol _DegreesToRadians in:
/Volumes/Store/NonPodVendor/ShareSDK/Extend/QQConnectSDK/TencentOpenAPI.framework/TencentOpenAPI(SetHeadImageViewController.o)
Library/Developer/Xcode/DerivedData/Products/Debug-iphonesimulator/libPods.a(JCNotificationBannerPresenterIOSStyle.o)
duplicate symbol _RadiansToDegrees in:
/Volumes/Store/NonPodVendor/ShareSDK/Extend/QQConnectSDK/TencentOpenAPI.framework/TencentOpenAPI(SetHeadImageViewController.o)
Library/Developer/Xcode/DerivedDataBuild/Products/Debug-iphonesimulator/libPods.a(JCNotificationBannerPresenterIOSStyle.o)
ld: 2 duplicate symbols for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
从上面的错误信息上看是不是ShareSDK中带的;Tencent的Framework中
与项目引用了同一个开源项目JSNotificationBannerPresenter 造成了冲突,
如果是的话,要怎么改才比较好呢?如果不是?是什么问题?

banxi1988 OP 自己解决了,就贴下解决办法方便后来人吧.
查看了JCNotificationBannerPresenterIOSStyle源代码, 发现有冲突的是以下可能是由以下两个函数名,可能编译后编译器将名字加了_前缀. CGFloat DegreesToRadians(CGFloat degrees) { return degrees * M_PI / 180.0; }; CGFloat RadiansToDegrees(CGFloat radians) { return radians * 180.0 / M_PI; }; 可能是作为两个简单的函数,跟其他的函数冲突了吧. 我的做法时,不在使用cocoapods管理此库,而是下载下来做为项目的一部分, 然后修改源代码: 将上面的函数名更改一下: CGFloat MyDegreesToRadians(CGFloat degrees) { return degrees * M_PI / 180.0; }; CGFloat MyRadiansToDegrees(CGFloat radians) { return radians * 180.0 / M_PI; }; 然后编译就通过了!~ |
