我收到了一个错误[Type＆＃34; View Controller＆＃34;不符合协议＆＃34; ORKTaskViewControllerDelegate＆＃34;]

Question

我刚开始在Xcode中使用swift3，以便利用Apple.inc提供的ResearchKit。 虽然我已经使用Swift的Researchkit教程中的教程：Ray Wenderlich的入门，但我在ViewController的扩展中遇到了麻烦。以下是我的代码。

import ResearchKit
import UIKit

class ViewController: UIViewController {

  override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
  }

  override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
  }

  @IBAction func consentTapped(sender : AnyObject) {
    let taskViewController = ORKTaskViewController(task: ConsentTask, taskRun: nil)
    taskViewController.delegate = self
    present(taskViewController, animated: true, completion: nil)
  }
}

extension ViewController: ORKTaskViewControllerDelegate {

  func taskViewController(taskViewController: ORKTaskViewController, didFinishWithReason
         reason: ORKTaskViewControllerFinishReason, error: NSError?) {
    //Handle results with taskViewController.result
    taskViewController.dismiss(animated:true, completion: nil)
  }
}

你错过了添加代表。将ORKTaskViewControllerDelegate添加到ViewController

class ViewController: UIViewController,ORKTaskViewControllerDelegate {
   override func viewDidLoad() {
    super.viewDidLoad(
   }
}
