上传文件到iPhone上的FTP服务器

I would like to implement logic that uploads file to FTP Server.

我想实现将文件上传至FTP服务器的逻辑。

I am new in iPhone development, so want to figure out preferred approach. After browsing available API for this task I have managed to find only code that uses CFNetwork (that looks like not Objective C based).

我是iPhone开发的新手，所以想要找到更好的方法。在浏览了此任务的可用API后，我只找到了使用CFNetwork的代码(看起来不是基于Objective - C的)。

There is also URL Loading System that uses NSURL etc which are Objective C based.

还有使用NSURL等基于Objective - C的URL加载系统。

So, my question: Is it possible to use URL Loading System to implement file upload to FTP Server?

那么，我的问题是:是否可以使用URL加载系统实现文件上传至FTP服务器?

Thanks.

谢谢。

I use a PHP Page to post a file to and have PHP handle the uploading....

我使用一个PHP页面发布文件,PHP处理上传....

This code is used to upload a photo, but it can be adapted to work with any file.

这段代码用于上传照片，但是可以对任何文件进行修改。

PHP Code:

PHP代码:

<?php
$uploaddir = 'photos/';
$file = basename($_FILES['userfile']['name']);
$uploadfile = $uploaddir . $file;

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
    echo "OK";
} else {
    echo "ERROR";
}

?>

iPhone Code:

iPhone代码:

- (BOOL)uploadImage:(NSData *)imageData filename:(NSString *)filename{


    NSString *urlString = @"http://www.yourdomainName.com/yourPHPPage.php";

    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
    [request setURL:[NSURL URLWithString:urlString]];
    [request setHTTPMethod:@"POST"];

    NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
    [request addValue:contentType forHTTPHeaderField: @"Content-Type"];

    NSMutableData *body = [NSMutableData data];
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@\"\r\n",filename]] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[NSData dataWithData:imageData]];
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [request setHTTPBody:body];

    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    NSString *returnString = [[[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding] autorelease];

    return ([returnString isEqualToString:@"OK"]);
}

Method Call:

方法调用:

[self uploadImage:UIImageJPEGRepresentation(imageView.image, 1.0) filename:imageName];
