大家好，又见面了，我是全栈君。
在静态库project中加入ASIHTTPRequest导出lib.a。放到project里编译出一下错：
Undefined symbols for architecture armv7:
“_deflate”, referenced from:
-[ASIDataCompressor compressBytes:length:error:shouldFinish:] in lib.a(ASIDataCompressor.o)
“_inflateInit2_”, referenced from:
-[ASIDataDecompressor setupStream] in lib.a(ASIDataDecompressor.o)
“_deflateEnd”, referenced from:
-[ASIDataCompressor closeStream] in lib.a(ASIDataCompressor.o)
“_inflateEnd”, referenced from:
-[ASIDataDecompressor closeStream] in lib.a(ASIDataDecompressor.o)
“_kUTTagClassMIMEType”, referenced from:

“_inflate”, referenced from:

“_UTTypeCopyPreferredTagWithClass”, referenced from:
+[ASIHTTPRequest mimeTypeForFileAtPath:] in lib.a(ASIHTTPRequest.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
解决方法：
缺系统库的原因，加入下面库
libz.dylib
SystemConfiguration.framework
MobileCoreAServices.framework
CFNetwork.framework
完毕
