这个问题快把我逼疯了,我不知道怎么解决它。

    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 status
Command /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1

我认为这与:

ld: symbol(s) not found for architecture armv7

但是我添加了:libz.1.2.3。Dylib并没有帮助,有人有什么想法吗?

If you're building from Unity3D 5 and also using a Prime31 plugin and you're getting this error it's probably due to a duplicate .dll. If you look through your warnings in Unity's editor one of them will tell you this and warn that it could cause build errors. To see if this is the case, type P31 in your project search field and it should pop right up, maybe even more than one. The duplicate's will have a ' 1' at the end of the file name. This is probably caused from updating the plugin in editor via the store or the Prime31 menu tab.

别名通常不包含链接到当前版本的版本标识符,在本例中为libz。Dylib链接到libz.1.2.5.dylib。使用基本别名,而不是版本化的别名。

我有这个警告,当在另一个类的.h文件中写两个类时,但忘记在.m文件中写这个类的实现。

对我来说,问题是我忘记在.m(实现)中为我的常量设置值

file const kFooKey = @"Foo";

尝试实现派生类的至少一个非内联函数。如果不这样做,链接器可能会避免为该类创建类型信息。

我没有在这里找到这个建议,所以它是这样的: 如果你的项目有多个目标(即一个OSX和一个iOS),那么你必须为每个目标链接相关的库。例如,在我的情况下,我需要AudioToolbox..我不得不为OSX和iOS添加一次(在框架文件夹下,你必须有每个目标的每个库的副本..如果你只看到一个..那么这就是一个危险信号)
