ld:找不到架构i386 Xcode单元测试的符号

Question

当我尝试运行单元测试时,我收到此错误.整个错误是:

    Undefined symbols for architecture i386:
  "_CGImageRelease", referenced from:
      _releaseImages in UIImage+animatedGIF.o

我在这里做了所有的指示:http: //twobitlabs.com/2011/06/adding-ocunit-to-an-existing-ios-project-with-xcode-4/

还将库添加到测试目标的Build Phrases中的"Compile Sources".仍然没有运气.

Answer 1

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.

以下是文件的完成方式:

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".
