I am getting this error when I try to run my unit tests. The entire error is:
当我尝试运行单元测试时出现此错误。整个错误是：

I did all the instructions here: http://twobitlabs.com/2011/06/adding-ocunit-to-an-existing-ios-project-with-xcode-4/
我在这里做了所有的说明：http: //twobitlabs.com/2011/06/adding-ocunit-to-an-existing-ios-project-with-xcode-4/
Also added the library to "Compile Sources" in Build Phrases of the test target. Still no luck.
还将库添加到测试目标的构建短语中的“编译源”。仍然没有运气。

Looks like you need to add "CoreGraphics.framework" and "ApplicationServices.framework" to your unit test target membership.
看起来您需要将“CoreGraphics.framework”和“ ApplicationServices.framework”添加到您的单元测试目标成员资格中。
Here's how it's done for a file:
以下是对文件的处理方式：
Just go to "CoreGraphics.framework" in the list of files and folders on the left side and make certain the checkmark is "ON" for the unit tests target.
只需转到左侧文件和文件夹列表中的“CoreGraphics.framework”，并确保单元测试目标的复选标记为“ON”。

Go to build phases of target, Add ImageIO.framework
转到目标的构建阶段，添加ImageIO.framework
