用于架構ARMv 7的未定義符號這個問題把我逼瘋了，我想不出怎么解決它.    Undefined symbols for architecture armv7:   "_deflateEnd", referenced from:       -[ASIDataCompressor closeStream] in ASIDataCompressor.o  "_OBJC_CLASS_$_ASIDataDecompressor", referenced from:       objc-class-ref in ASIHTTPRequest.o  "_deflate", referenced from:       -[ASIDataCompressor compressBytes:length:error:shouldFinish:] in ASIDataCompressor.o  "_deflateInit2_", referenced from:       -[ASIDataCompressor setupStream] in ASIDataCompressor.o ld: symbol(s) not found for architecture armv7 collect2: ld returned 1 exit statusCommand /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1我認為這與：ld: symbol(s) not found for architecture armv7但我補充說：libz.1.2.3.dylib沒什么用，有人有什么主意嗎？
