尝试在模拟器中运行应用时出现此错误。我正在使用这个库。 https://github.com/donobono/DoImagePickerController。我怎么解决这个问题？
Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_DoImagePickerController", referenced from:
objc-class-ref in NewActivityVC.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
提前谢谢
