Error while uploading file - ios

Question

I m uploading image using post method but every time i find following error:
The operation couldn’t be completed. (NSURLErrorDomain error -1012.)
Please suggest me the way by which i can resolve this issue:(
NSString *urlString = [NSString stringWithFormat:#"%#%#",Base_URL,URL_Upload];
NSURL* requestURL = [NSURL URLWithString:urlString];
NSString *filename = imageName;
//creating request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:#"POST"];
// set URL
[request setURL:requestURL];
// set Content-Type in HTTP header
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#", boundary];
[request setValue:contentType forHTTPHeaderField: #"Content-Type"];
// post body
NSMutableData *postbody = [NSMutableData data];
NSData* imageData = UIImageJPEGRepresentation(image, 1);
if (imageData) {
[postbody appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
NSString* fileData = [NSString stringWithFormat:#"Content-Disposition: form-data; name=\"file\"; filename=\"%#\"\r\n", filename];
NSLog(#"fileData %#",fileData);
[postbody appendData:[fileData dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:#"Content-Type: image/jpeg\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:imageData];
[postbody appendData:[[NSString stringWithFormat:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}
[postbody appendData:[[NSString stringWithFormat:#"--%#--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:postbody];
// set the content-length
NSString *postLength = [NSString stringWithFormat:#"%d", [postbody length]];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
_connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[_connection start];
if (_connection) {
_reposnseData = [NSMutableData data];
}
