我有一个在 i386/iOS 模拟器上构建和运行良好的 MonoTouch 项目。该项目引用了一个本机 (Obj-C) 库，我使用 Xamarin 的 BindingSample 中描述的 btouch 过程将其转换为 MonoTouch DLL：

https://github.com/xamarin/monotouch-samples/tree/eb640165f0485ff59b2f80e73ccff382bf4f2083/BindingSample/src/binding

因此，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“通用”库，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，我检查了lipo -info，确实，它包含 i386、armv6 和 armv7。

但是，当我在实际的 iOS 设备上进行部署时，我收到以下错误：

Undefined symbols for architecture armv7:

mtouch exited with code 1

我究竟做错了什么？

发现问题：原生库依赖于AddressBook框架，忘记在API定义项目的AssemblyInfo.cs中包含：

[assembly: LinkWith ("libContactsTokenFieldViewUniversal.a", LinkTarget.Simulator | LinkTarget.ArmV6 | LinkTarget.ArmV7, ForceLoad = true, Frameworks="AddressBook Foundation")]
