AFNetworking報錯_UTTypeCopyPreferredTagWithClass, referenced from: _AFContentTypeForPathEx

編輯:IOS開發綜合

此篇文章將要引見A.networking報錯"_UTTypeCopyPreferredTagWithClass", referenced from: _AFContentTypeForPathExtens的相關引見,詳細實例請看下文

問題: 在和Unity交互的進程中,從Unity開發工具打包出來的項目文件,在添加A.networking庫,運轉時報出以下錯誤:

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)

A.networking報錯"_UTTypeCopyPreferredTagWithClass", referenced from: _AFContentTypeForPathExtens

緣由是未添加 MobileCoreServices.framework(此框架定義一致類型標識符 (UTIs)運用的底層類型)

處理:Build Phase ->Link Binary With Libraries()下添加MobileCoreServices.framework。添加成功後運轉順序成功。
