ld：找不到架构i386 Xcode单元测试的符号

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

还在测试目标的Build Phrases中将库添加到“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”。

Answer 2

转到构建目标阶段，添加 ImageIO.framework
