如何在iOS中录制后将视频上传到FTP服务器？

Question

NSURL *mediaURL=[info objectForKey:UIImagePickerControllerMediaURL]; 
NSData *videoData=[NSData dataWithContentsOfURL:_videoURL]; 
NSString *moviePath=[mediaURL path]; 
SCRFTPRequest *ftpRequest=[[SCRFTPRequest alloc] initWithURL:[NSURL   URLWithString:@"ftp://xyz.ca/"] toUploadFile:[mediaURL path]]; 
ftpRequest.username = @"xyz.ca"; 
ftpRequest.password = @"buKMH3ko8Nn"; 

//Specify a custom upload file name (optional) 
ftpRequest.customUploadFileName = @"h.MOV"; 
//The delegate must implement the SCRFTPRequestDelegate protocol 
ftpRequest.delegate = self; 
[ftpRequest startRequest]; 

但是这会上传零大小的文件。

我在didFinishPickingMediaWithInfo：delegate方法中使用上面的代码。 请帮帮我。

只是通过NSData的这种方法

- (NSData *)generatePostDataForData:(NSData *)uploadData 
{ 
    // Generate the post header: 
    NSString *post = [NSString stringWithCString:"--AaB03x\r\nContent-Disposition: form-data; name=\"upload[file]\"; filename=\"somefile\"\r\nContent-Type: application/octet-stream\r\nContent-Transfer-Encoding: binary\r\n\r\n" encoding:NSASCIIStringEncoding]; 

    // Get the post header int ASCII format: 
    NSData *postHeaderData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; 

    // Generate the mutable data variable: 
    NSMutableData *postData = [[NSMutableData alloc] initWithLength:[postHeaderData length] ]; 
    [postData setData:postHeaderData]; 

    // Add the image: 
    [postData appendData:uploadData]; 

    // Add the closing boundary: 
    [postData appendData:[@"\r\n--AaB03x--" dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]]; 

    // Return the post data: 
    return postData; 
} 


// For post video use this function 

- (void)post:(NSData *)fileData 
{ 
    NSLog(@"POSTING"); 

    // Generate the postdata: 
    NSData *postData = [self generatePostDataForData: fileData]; 
    NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; 

    // Setup the request: 
    NSMutableURLRequest *uploadRequest = [[[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.example.com:3000/"] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:30] autorelease]; 
    [uploadRequest setHTTPMethod:@"POST"]; 
    [uploadRequest setValue:postLength forHTTPHeaderField:@"Content-Length"]; 
    [uploadRequest setValue:@"multipart/form-data; boundary=AaB03x" forHTTPHeaderField:@"Content-Type"]; 
    [uploadRequest setHTTPBody:postData]; 

    // Execute the request: 
    NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:uploadRequest delegate:self]; 
    if (conn) 
    { 
     // Connection succeeded (even if a 404 or other non-200 range was returned). 
     NSLog(@"success"); 
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Got Server Response" message:@"Success" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
     [alert show]; 
     [alert release]; 
    } 
    else 
    { 
     // Connection failed (cannot reach server). 
     NSLog(@"fail"); 
    } 
}
