iphone - 添加 S7FTPRequest 后，iPhone 应用程序无法编译

Question

iPhone 应用程序开发新手，在将 S7FTPRequest 包含到类库中后，我在编译(或“构建并运行”)应用程序时遇到问题；在我将它包含在任何特定脚本中之前。我收到以下错误:

Undefined symbols:
"_kCFStreamPropertyFTPPassword", referenced from:
_kCFStreamPropertyFTPPassword$non_lazy_ptr in S7FTPRequest.o
(maybe you meant: _kCFStreamPropertyFTPPassword$non_lazy_ptr)
"_CFWriteStreamCreateWithFTPURL", referenced from:
-[S7FTPRequest startUploadRequest] in S7FTPRequest.o
-[S7FTPRequest startCreateDirectoryRequest] in S7FTPRequest.o
"_kCFStreamPropertyFTPUserName", referenced from:
 _kCFStreamPropertyFTPUserName$non_lazy_ptr in S7FTPRequest.o
 (maybe you meant: _kCFStreamPropertyFTPUserName$non_lazy_ptr)
"_kCFStreamErrorDomainFTP", referenced from:
 _kCFStreamErrorDomainFTP$non_lazy_ptr in S7FTPRequest.o
 (maybe you meant: _kCFStreamErrorDomainFTP$non_lazy_ptr)
ld: symbol(s) not found
collect2: ld returned 1 exit status

谢谢!

你搞错了一点。问题的出现是由于链接缺少所需的框架，但所需的框架是 CFNetwork.framework 而不是 libz.1.2.3.dylib

libz动态库用于压缩/解压缩操作。
