我按照以下步骤操作：http: //ocmock.org
还有这些： http ://twobitlabs.com/2011/06/adding-ocunit-to-an-existing-ios-project-with-xcode-4/
虽然我无法成功地让 twobitlabs 指令的第 4 步工作。意思是“单击构建设置选项卡并将捆绑加载程序设置设置为$（BUILT_PRODUCTS_DIR）/MyExistingApp.app/MyExistingApp”......当我这样做时，我得到：

clang: error: linker command failed with exit code 1 (use -v to see invocation)
然而，当我在我的终端中复制/粘贴该路径时，它肯定存在..正如您在此处看到的：
>ls -l /Users/patrick/Library/Developer/Xcode/DerivedData/Notes_and_Clefs-fpzvpdfkkkjuynefaqeajfdiznbp/Build/Products/Debug-iphonesimulator/Notes\ and\ Clefs.app/Notes\ and\ Clefs

所以，我不知道我的文件中是否有空格是否有问题......
如果我跳过这一步，当我运行测试时，我会收到臭名昭著的错误：
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_Question", referenced from:
objc-class-ref in UnitTests.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
test.m 文件似乎不理解我正在测试的实际类的标头是什么，尽管我在 test.h 的标头中使用了 #import "Question.h" ...（另外，将其直接添加到.m 什么都不做）。
