将项目移动到Xcode 4.2,我得到了许多Mach-O链接器未解决的错误,例如_crc32,_expf和_UnwindSjLj_Register,这些项目在Xcode 4.0.3中编译和链接很好.

我怀疑这可能是一个libz问题,因为我之前的项目链接了libz.1.2.3.dylib.我删除了该引用,并添加了libz.1.2.5.dylib,它位于我的/Platforms/iPhoneOS.platform/DeviceSupport/5.0(9A5259f)/ Symbols 1/usr/lib文件夹中.

无论是否包含libz.1.2.5.dylib,我都得到相同的39个未解析的引用,所以它似乎非常可疑.

我是iPad开发人员的新手,我想在我的项目中创建ePub文件,

我从这里下载了示例epub文件, 我遇到了问题.

我在我的项目中得到了这个错误......

这让我发疯,当我尝试在模拟器上编译时,一切都很好,但在设备上我得到了这个错误:

ld: library not found for -lz
Command /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/clang failed with exit code 1

请帮我理解问题的根源:

编辑:

我确实导入了libz.1.1.3.dylib框架:

我在Linked框架中获得的唯一libz就是 libz.1.1.3.dylib

我正在创建一个unizp文件的应用程序,在谷歌搜索后我发现我们可以使用已经在Cocoa touch中提供的libz.dylib.我觉得奇怪的是,我无法找到libs.dylib的任何文件.任何人都可以提供一些官方文件吗？而且如果我们想要解压缩文件,每个人都建议使用一些第三方库来解压缩文件.我们不能用默认的libz.dylib吗？
