Question

my program is write for upload the picture from the cam,sample code below:

    #define WEBSERVICE_URL @"http://192.168.0.104/upload.php"
    - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

        [picker dismissViewControllerAnimated:YES completion:^{

            UIImage *selectedImage = [info objectForKey:UIImagePickerControllerOriginalImage];

            NSData *imageData = UIImagePNGRepresentation(selectedImage);

            NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:WEBSERVICE_URL parameters:nil constructingBodyWithBlock:^(id formData) {
                [formData appendPartWithFileData:imageData name:@"upfile" fileName:@"test" mimeType:@"image/png"];
            } error:nil];

            AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

            NSProgress *progress = nil;

            NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:&progress completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {

                [progress removeObserver:self forKeyPath:@"fractionCompleted"];
                NSLog(error.debugDescription);


                if (error) {
                    [self.view updateWithMessage:[NSString stringWithFormat:@"Error : %@!", error.debugDescription]];
                } else {
                    [self.view updateWithMessage:@"Great success!"];

                }
            }];

            [progress addObserver:self forKeyPath:@"fractionCompleted" options:NSKeyValueObservingOptionNew context:NULL];

            [uploadTask resume];

            self.imageUploadProgress = [[TNSexyImageUploadProgress alloc] init];
            self.imageUploadProgress.radius = 100;
            self.imageUploadProgress.progressBorderThickness = -10;
            self.imageUploadProgress.trackColor = [UIColor blackColor];
            self.imageUploadProgress.progressColor = [UIColor whiteColor];
            self.imageUploadProgress.imageToUpload = selectedImage;
            [self.imageUploadProgress show];

            [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(imageUploadCompleted:) name:IMAGE_UPLOAD_COMPLETED object:self.imageUploadProgress];

        }];
    }

the error is :

TNSexyImageUploadProgressDemo[5275:113032] Error Domain=NSURLErrorDomain Code=-1001 "The operation couldn’t be completed. (NSURLErrorDomain error -1001.)"

        $result_json['error'] = 'Exceeded filesize';
    }

    $finfo = new finfo(FILEINFO_MIME_TYPE);

    if (false === $ext = array_search(
        $finfo->file($_FILES['upfile']['tmp_name']),
            array(          
                'png' => 'image/png'           
            ),
            true

    }

    if (!move_uploaded_file(
        $_FILES['upfile']['tmp_name'],
        sprintf('./uploads/%s.%s',
            sha1_file($_FILES['upfile']['tmp_name']),
            $ext
        )
        )) {
            $result_json['error'] = 'Failed to move uploaded file';
    }

    // send the result now
    echo json_encode($result_json);

    /*

            )) {
                //throw new RuntimeException('Failed to move uploaded file.');
        }

        //echo json_encode(array('succes'=>true));
    } catch (RuntimeException $e) {

        //echo $e->getMessage();

    }

I was having the same problem since I started using Xcode 6. Updating the AFNetworking library fixed the problem. Everything is working fine again.

If you're using Xcode 6, give it a try.
