• AFNetworking 使用中报错


    好久没用 http相关的库,今天使用, 选用AFNetworking,github下载,引入工程,记录下中间使用中遇到的问题

     

    1.在非ARC工程中使用ARC的文件,在project->Build Phases->Compile Sources 文件编辑参数 -fobjc-arc

     PS:在ARC项目中使用非ARC文件:文件编辑参数 -fnoobjc-arc

     

    2.编译时报错,

    Undefined symbols for architecture i386:
      "_UTTypeCopyPreferredTagWithClass", referenced from:
          _AFContentTypeForPathExtension in AFURLRequestSerialization.o
      "_UTTypeCreatePreferredIdentifierForTag", referenced from:
          _AFContentTypeForPathExtension in AFURLRequestSerialization.o
      "_kUTTagClassFilenameExtension", referenced from:
          _AFContentTypeForPathExtension in AFURLRequestSerialization.o
      "_kUTTagClassMIMEType", referenced from:
          _AFContentTypeForPathExtension in AFURLRequestSerialization.o
    ld: symbol(s) not found for architecture i386
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

    解决 project->Build Phases-> Link Binary With Libraries 添加
    MobileCoreServices.framework
    SystemConfiguration.framework

    3. 请求url 出现错误:The resource could not be loaded because the App Transport Security policy requires the use of a secure connection. 
    原因iOS9引入了新特性App Transport Security (ATS),要求App内访问的网络必须使用HTTPS协议。

      解决方案: 1.在Info.plist中添加NSAppTransportSecurity类型Dictionary

           2.在NSAppTransportSecurity下添加NSAllowsArbitraryLoads类型Boolean,值设为YES

    4.编译出现   AF_Require_noErr(SecItemExport(key, kSecFormatUnknown, kSecItemPemArmour, NULL, &data), _out);  出现kSecFormatUnknown无法识别  如果是2.6版本,请换2.5 就没问题了
