Question

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：

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

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i386，armv6和armv7。

但是，当我在实际的iOS设备上构建部署时，我会收到以下错误：

Undefined symbols for architecture armv7:

ld: symbol(s) not found for architecture armv7

mtouch exited with code 1

我做错了什么？

Answer 1

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")]

MonoTouch Build：ld：未找到架构armv7的符号
