options:kNilOptions error:nil];
NSURL * url=[NSURL URLWithString:#"http://xxxxxx/finalresult1"];
NSMutableURLRequest *request=[[NSMutableURLRequest alloc]initWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:120.0];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:config];
NSURLSessionDataTask* task = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
{
if (error == nil)
{
// Success
NSLog(#"URL Session Task Succeeded: HTTP %ld", ((NSHTTPURLResponse*)response).statusCode);
NSString * text = [[NSString alloc] initWithData: data encoding:
NSUTF8StringEncoding];
NSLog(#"Data = %#",text);
NSLog(#"erroer is %#",error);
}

Change request Content-Type, Use:
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
