ios - 如何修复架构arm64错误的 undefined symbol ？

Question

我遇到了这个架构问题？

   Undefined symbols for architecture arm64:
      "_CGImageGetWidth", referenced from:
          GetBytesFromCGImage(CGImage*, int*, int*, int*) in OSInference.o
      "_CGColorSpaceCreateDeviceRGB", referenced from:
          GetBytesFromCGImage(CGImage*, int*, int*, int*) in OSInference.o
      "_CGBitmapContextCreate", referenced from:
          GetBytesFromCGImage(CGImage*, int*, int*, int*) in OSInference.o
      "_CGImageGetHeight", referenced from:
          GetBytesFromCGImage(CGImage*, int*, int*, int*) in OSInference.o
      "_CGColorSpaceRelease", referenced from:
          GetBytesFromCGImage(CGImage*, int*, int*, int*) in OSInference.o
      "_CGContextDrawImage", referenced from:
          GetBytesFromCGImage(CGImage*, int*, int*, int*) in OSInference.o
      "_CGContextRelease", 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)

我做了什么

1. 在构建阶段 - 将二进制文件与我添加的库链接起来 AVKit、CoreGraphics、QuartzCore

2.仅构建架构 - 否

有什么办法可以解决这个问题吗？
