Example
NSURL *url = [NSURL URLWithString:@"http://www.example.com/"]; NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration]; // Configure the session here. NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration]; [[session dataTaskWithURL:url completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { // The response object contains the metadata (HTTP headers, status code) // The data object contains the response body // The error object contains any client-side errors (e.g. connection // failures) and, in some cases, may report server-side errors. // In general, however, you should detect server-side errors by // checking the HTTP status code in the response object. }] resume];
