AFNetworking报错"_UTTypeCopyPreferredTagWithClass", referenced from: _AFContentTypeForPathExtens

问题: 在和Unity交互的过程中,从Unity开发工具打包出来的项目文件,在添加AFNetworking库,运行时报出以下错误:

Undefined symbols for architecture armv7:

  "_kUTTagClassMIMEType", referenced from:

      -[AFStreamingMultipartFormData appendPartWithFileURL:name:error:] in AFURLRequestSerialization.o

  "_kUTTagClassFilenameExtension", referenced from:

      -[AFStreamingMultipartFormData appendPartWithFileURL:name:error:] in AFURLRequestSerialization.o

  "_UTTypeCreatePreferredIdentifierForTag", referenced from:

      -[AFStreamingMultipartFormData appendPartWithFileURL:name:error:] in AFURLRequestSerialization.o

  "_UTTypeCopyPreferredTagWithClass", referenced from:

      -[AFStreamingMultipartFormData appendPartWithFileURL:name:error:] in AFURLRequestSerialization.o

ld: symbol(s) not found for architecture armv7

clang: error: linker command failed with exit code 1 (use -v to see invocation)

 

 

原因是未添加 MobileCoreServices.framework(此框架定义统一类型标识符 (UTIs)使用的底层类型)

解决:Build Phase ->Link Binary With Libraries()下添加 MobileCoreServices.framework。添加成功后运行程序成功。
