将file upload到iPhone上的FTP服务器

我想实现将file upload到FTP服务器的逻辑。

我是iPhone新手,所以想弄清楚首选的方法。 浏览可用的API为这个任务,我已经设法find只使用CFNetwork的代码(这看起来像不是Objective C的基础)。

还有URL加载系统,它使用基于Objective C的NSURL等。

所以,我的问题:是否可以使用URL加载系统实现file upload到FTP服务器?

谢谢。

我使用PHP页面发布文件,并有PHP处理上传….

此代码用于上传照片,但可以适用于任何文件。

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"]); } 

方法调用:

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