我有一个MonoTouch项目,可以在i386 / iOS模拟器上构建和运行.该项目引用了一个本机(Obj-C)库,我通过使用Xamarin的BindingSample中描述的btouch进程将其转换为MonoTouch DLL：
所以我的makefile构建了所有三种架构(i386,armv6和armv7),然后将三个输出组合到一个’Universal’库中,最后使用btouch生成MonoTouch DLL.
为了确保我的通用库包含所有三种体系结构,我使用lipo -info进行了检查,实际上它包含了i386,armv6和armv7.
但是,当我在实际的iOS设备上进行部署时,我会收到以下错误：
Undefined symbols for architecture armv7:

我究竟做错了什么？
解决方法
发现问题：本地库依赖于AddressBook框架,我忘了将它包含在API定义项目的AssemblyInfo.cs中：
[assembly: LinkWith ("libContactsTokenFieldViewUniversal.a",LinkTarget.Simulator | LinkTarget.ArmV6 | LinkTarget.ArmV7,ForceLoad = true,Frameworks="AddressBook Foundation")]
