Upload large file video to server in ios - ios

Question

I have to create application for upload video to server in ios. I am using code for upload video which is given below. This code upload small video and working nicely but above 5 mb video can't upload .
- (void)uploadvideo {
NSString *strurl=[NSString stringWithFormat:#"%#",appDele.DRUPAL_SERVICES_URL];
NSString *url=[[NSString alloc]initWithFormat:#"video_upload.php?user_id=%#&node_id=%#",appDele.UserId,appDele.strProductId];
NSString *urlString =[NSString stringWithFormat:#"%#%#",strurl,url] ;
NSLog(#"%#",urlString);
NSString *encodedString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
// setting up the request object now
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:encodedString]];
[request setHTTPMethod:#"POST"];
//[request setTimeoutInterval:10000];
// NSInputStream *videoStream = [[[NSInputStream alloc] initWithData:data1] autorelease];
// [request setHTTPBodyStream:videoStream];
NSString *boundary = [NSString stringWithFormat:#"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
/*
now lets create the body of the post
*/
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"filename\"; filename=\"New.mp4\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// NSLog(#"%#New.jpg",appDelegate.MemberId);
[body appendData:[[NSString stringWithFormat:#"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// [body appendData:data1.length];
[body appendData:[NSData dataWithData:data1]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
// now lets make the connection to the web
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(#"%#",returnString);
}
Any suggestion on how to upload large video file in ios?

NSURLConnection is quite old, take a look at NSURLSession with it's delegates and blocks. Here's some tutorial, how to migrate from one to another.
