    return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]];
  } completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) {
    NSString* content = [NSString stringWithContentsOfFile:filePath.relativePath encoding:NSUTF8StringEncoding error:NULL];
    NSLog(@"content = %@", content);
    //save this content to your NSUserDefaults
  [downloadTask resume];
