我试图在我的项目中添加一个testunit目标但是失败了。我的testunit需要libxml2.dylib（实际上是libxml2.2.dylib），当然还有sentestingunit.framework。我将libxml2.dylib添加到构建设置中的FRAMEWORK_SEARCH_PATHS $（继承）“$（SYSTEM_APPS_DIR）/Xcode.app/Contents/Developer/Library/Frameworks”
然后我在构建阶段添加sentestingunit.framework - >使用库链接二进制文件。我有我的应用程序（称为vindfyrar）作为目标依赖项。现在，我的测试目标的构建开始尖叫下面的所有内容;谁知道我做错了什么？ i386的？为什么？
相信我这个，我完成了我的作业，我用Google搜索并尝试构建设置中的每个选项都可能是错误的......没有成功。 Lion 10.7.5上的XCode 4.6

您正在链接iPhoneOS SDK（所有二进制文件都是为架构部门构建的），但您正在构建一个iPhone模拟器程序（i386）。您的项目正在链接错误的SDK。
我通过添加这些设置和值解决了这个问题。
对于测试主机它是$（BUNDLE_LOADER）对于Bundle Loader它是$（BUILT_PRODUCTS_DIR）/ApplicationName.app/ApplicationProductName
如果您需要更多详细信息，请登录apple.developer并搜索“测试用例给Apple Mach-O链接器错误”
谢谢大家的时间！
