xcode - ld : symbol(s) not found for architecture i386 Xcode unit tests

Question

当我尝试运行单元测试时出现此错误。整个错误是:

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

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/

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。

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中。

这是对文件的处理方式:

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”。
