我得到了一個錯誤[類型「視圖控制器」不符合協議「ORKTaskViewControllerDelegate」]

Question

我剛開始在Xcode中使用swift3以利用Apple.inc提供的ResearchKit。 雖然我已經通過研究工具教程中的Swift教程：Ray Wenderlich入門，但我在ViewController的擴展中遇到了麻煩。以下是我的代碼。

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) 
    } 
}

您錯過了添加委託。將ORKTaskViewControllerDelegate添加到ViewController

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