Ios 如何修复架构arm64错误的未定义符号？

我得到了这个建筑问题

   Undefined symbols for architecture arm64:
      "_CGImageGetWidth", referenced from:
          GetBytesFromCGImage(CGImage*, int*, int*, int*) in OSInference.o

    ld: symbol(s) not found for architecture arm64
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

我所做的

在构建阶段-使用我添加的库链接二进制文件 AVKit、CoreGraphics、QuartzCore

2.仅构建架构-无

有什么办法可以解决这个问题吗？

1-将

CoreGraphics

框架添加到您的项目中

2-导入

CoreGraphics

3-清理您的项目

4-再次尝试构建

尝试更改“仅构建活动体系结构”为“是”，谢谢，但会出现这样的错误------没有要编译的体系结构（仅活动体系结构=是，活动体系结构=arm64，有效体系结构=armv7 armv7s）。我同意。请确保您正在相关源文件中导入它并将其添加到项目中（在构建阶段，正如您正在做的那样）。
