在Objective-C iOS上将东西上传到FTP [英] Upload things to a FTP in Objective-C iOS

问题描述

前几天我问了如何从FTP下载文件，并解决了我使用NSData和dataWithContentsOfURL这样的问题：

ftp：// user：pass@server/path/of/file.extension

但现在我需要上传一个文件，而我想知道是否有任何指令通过URL上传文件，但我认为这是不可能的，许多我看到iOS的库使用PHP，我不想要它，而Apple的SimpleFTPSample对于初级开发人员来说是如此令人困惑我什么都不懂，所以上传一个简单的代码来指定URL，路径，文件，用户和密码？如果你想要一个简单的库，我会推荐使用HTTP和AFNetworking库。

然而，如果你想做FTP，Apple提供了一步一步的指导。这有点多毛，所以我建议只是复制和粘贴，并根据需要调整。你将不得不阅读文件一点点。查找上传文件部分。

http://developer.apple.com/library/ios/#documentation/Networking/Conceptual/CFNetwork/CFFTPTasks/CFFTPTasks.html

这应该有助于苹果不提供代码的初始部分

  CFStringRef url = CFSTR（ftp://ftp.somedomain.com/file.txt）; 
 CFURLRef requestURL = CFURLCreateWithString（kCFAllocatorDefault，url，NULL）; 
 
 CFReadStreamRef readStream = CFReadStreamCreateWithFTPURL（kCFAllocatorDefault，requestURL）; 
  

希望这会有所帮助。

Some days ago I was asking how to download files from a FTP and I solver my problem with NSData and dataWithContentsOfURL of this kind:

ftp://user:pass@server/path/of/file.extension

But now I need to upload a file, and I was wondering if there is any instruction to upload files through an URL but I think it could not be possible and many many libraries I saw for iOS use PHP and I don't want it, and SimpleFTPSample from Apple is so confusing for junior developers that I could not understand nothing, so a simple code to upload a file specifying URL, Path, File, user and pass?

解决方案

If you would like an easy library I would recommend using HTTP and the AFNetworking library.

However if you want to do FTP, Apple provides step by step instructions. It is a bit hairy, so I recommend just copy and pasting and tweaking as necessary. You will have to read the docs a tiny bit. Look for the "Uploading a File" section.

http://developer.apple.com/library/ios/#documentation/Networking/Conceptual/CFNetwork/CFFTPTasks/CFFTPTasks.html

This should help with the initial part that apple does not provide the code for

CFStringRef url = CFSTR("ftp://ftp.somedomain.com/file.txt");
CFURLRef requestURL = CFURLCreateWithString(kCFAllocatorDefault, url, NULL);

CFReadStreamRef readStream = CFReadStreamCreateWithFTPURL(kCFAllocatorDefault, requestURL);

Hope this helps.
