我一直在寻找新的AFNetworking 2.0上传图像的例子.但是我正在撞墙,无法弄清楚代码有什么问题.所以这是我使用的代码

NSData *imageData = UIImageJPEGRepresentation(image, 0.5);
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];


AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

NSURL *URL = [NSURL URLWithString:@"http://myserverurl.com"];

NSURLRequest *request = [NSURLRequest requestWithURL:URL]; 

NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request fromData:imageData progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
    if (error) {
        NSLog(@"Error: %@", error);
    } else {
        NSLog(@"Success: %@ %@", response, responseObject);
    }
}];
[uploadTask resume];

TIA

-(IBAction)uploadToServer :(id)sender
{
    NSString *str1=[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"intro.mp4"];
    NSLog(@"str1=%@",str1);

    NSString *escapedUrlString = [str1 stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    NSLog(@"escapedUrlString=%@",escapedUrlString);

    NSURL *videoURL = [NSURL URLWithString:escapedUrlString];
    NSLog(@"videoURL=%@",videoURL);

    NSData *newdata = [NSData dataWithContentsOfFile:escapedUrlString];
    webdata=[NSData dataWithData:newdata];
    NSLog(@"webData = %@",webdata);
   [self post:webdata];
    }

- (void)post:(NSData *)fileData
{

    NSData *videoData = fileData;
    NSString *urlString = @"http://rompio.com/web_service/web.php?method=upload_video&user_id=4";

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

    NSString *boundary = @"---------------------------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] …
