我在目前的Xamarin项目中使用cocoapod SWRevealViewController和Xamarin .net binding。我使用XCode在本地创建了一个新的静态库，并添加了SWRevealViewController pod以构建arm64架构。我为模拟器（i386和x86_64）和设备（armv7和arm64）构建了新的库，并使用lipo将两个初始库组合成一个通用库。使用：＆＃34;文件lib.a＆＃34;，我可以看到新的通用库包含所有四种体系结构。
当我用Xamarin项目中的新静态库替换原始库SWRevealViewControllerSDK.a时，我遇到两个问题：
o对于模拟器，我遇到运行时错误：
Unknown class SWRevealViewController in Interface Builder file.
o对于设备，我收到构建时错误：
MTOUCHTASK: error MT5211: Native linking failed, undefined Objective-C class: _OBJC_CLASS_$_SWRevealViewController. If '_OBJC_CLASS_$_SWRevealViewController' is a protocol from a third-party binding, please check that it has the [Protocol] attribute in its api definition file, otherwise verify that all the necessary frameworks have been referenced and native libraries are properly linked in.
MTOUCHTASK: error MT5211: Native linking failed, undefined Objective-C class: _OBJC_CLASS_$_SWRevealViewControllerSegue. If '_OBJC_CLASS_$_SWRevealViewControllerSegue' is a protocol from a third-party binding, please check that it has the [Protocol] attribute in its api definition file, otherwise verify that all the necessary frameworks have been referenced and native libraries are properly linked in.
MTOUCHTASK: error MT5202: Native linking failed. Please review the build log.
如果我不使用lipo制作通用库，只需为模拟器和设备添加两个初始静态库，一切正常，只需获取未用于目标体系结构的库的链接器警告。
任何人都知道为什么我使用通用库时会遇到问题，而使用两个初始库它可以正常工作？
