如何在按鈕操作上從UIView移動到UIViewcontroller

Question

我在UIView上有一個按鈕，想要在按鈕點擊時初始化一個UIViewcontroller 。 我試圖在按鈕單擊時顯示另一個ViewController ，但我收到錯誤：

reason：'[setValue：forUndefinedKey：]：此類與密鑰AboutUser不符合密鑰值編碼。

// Protocol in UIView Class
protocol TinderCardDelegate: NSObjectProtocol {
    func didInfoButtonTapped()
}

class TinderCard: UIView {
    @objc func info_Btn_Action(sender: UIButton) {
       print("tap")
       delegate?.didInfoButtonTapped()        
    }
}

// Code in UIViewController
class SwipeViewController: UIViewController 
    override func viewDidLoad() {
       super.viewDidLoad()
    }

    func btninfoTapped() {
        print("tappp")
        let storyboard: UIStoryboard = UIStoryboard (name: 
        "UserProfileInfo", bundle: nil)

        let vc: UserInfoViewController = 
        storyboard.instantiateViewController(withIdentifier: 
        "UserInfoViewController") as! UserInfoViewController

        self.present(vc, animated: false, completion: nil)
    }
 }

extension SwipeViewController : TinderCardDelegate {

    func didInfoButtonTapped() {
         print("Button tapped ")
         self.btninfoTapped()
    }
}

回復：mab是你從另一個控制器復制粘貼按鈕請刪除該類的操作並為該類提供操作
