Can not upload video with multi part POST in AFNETWORKING on iOS - ios

Question

I tried below code to upload video with Multi part form POST in AFnetworking but when uploading, video sent about 80% is broken. This is my code:
-(void) uploadVideoAPI: (NSString*) emailStr andSumOfFiles: (NSString*) sumSizeFile andVideoNams:(NSMutableArray*) videoNameArr andUpFile :(NSMutableArray *) videoDataArray
{
NSURL *url = [NSURL URLWithString:#"http://myserver.com];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL: url] ;
NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:#"POST" path:nil parameters:nil constructingBodyWithBlock:^(id <AFMultipartFormData>formData) {
[formData appendPartWithFormData:[emailStr dataUsingEncoding:NSUTF8StringEncoding]
name:#"emailStr"]; //parametters1
[formData appendPartWithFormData:[sumSizeFile dataUsingEncoding:NSUTF8StringEncoding] name:#"sumSizeFile"];//parametters 2
for(int i=0;i<[videoDataArray count];i++)
{
NSString * videoName = [videoNameArr objectAtIndex:i];
NSData *videoData = [videoDataArray objectAtIndex:i];
[formData appendPartWithFileData:videoData
name:#"videos"
fileName:videoName mimeType:#"video/quicktime"];
}
}];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
NSLog(#"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite);
}];
[httpClient enqueueHTTPRequestOperation:operation];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Upload Complete");
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"error: %#", operation.responseString);
NSLog(#"%#",error);
}];
[operation start];
}
My code has any problem? Please give me some advice. thanks in advance

I suggest you to use appendPartWithFileURL instead of appendPartWithFormData for files, to avoid memory problems (imagine big data like video or compressed data files).
I use something like this:
// Create request
NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:#"POST" path:nil parameters:nil constructingBodyWithBlock:^(id <AFMultipartFormData>formData) {
// Important!! : file path MUST BE real file path (so -> "file://localhost/.../../file.txt") so i use [NSURL fileURLWithPath:]
NSError* err;
[formData appendPartWithFileURL:[NSURL fileURLWithPath:filePathToUpload] name:[fileInfo objectForKey:#"fileName"] error:&err];
}];
