You can rewrite it using NSURLSession as follows

    [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];

    NSString *token ; //GET THE TOKEN FROM THE KEYCHAIN

    NSString *authValue = [NSString stringWithFormat:@"Token %@",token];

    //Configure your session with common header fields like authorization etc
    NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
    sessionConfiguration.HTTPAdditionalHeaders = @{@"Authorization": authValue};

    NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];

    NSString *url;
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:url]];

    NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
        [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
        if (!error) {
            NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
            if (httpResponse.statusCode == 200){
                NSDictionary *jsonData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers|NSJSONReadingAllowFragments error:nil];

                //Process the data
            }
        }

    }];
    [task resume];
