//Init the NSURLSession with a configuration 
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration]; 
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: nil delegateQueue: [NSOperationQueue mainQueue]]; 

//Create an URLRequest 
NSURL *url = [NSURL URLWithString:@"Your URL"]; 
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url]; 


[urlRequest setHTTPMethod:@"GET"]; 
[urlRequest setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; 

//Create task 
NSURLSessionDataTask *dataTask = [defaultSession dataTaskWithRequest:urlRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { 
    //Handle your response here 
    // NSLog(@"resultsDictionary is %@",response);
