ios - 如何在按钮操作上从 UIView 移动到 UIViewcontroller

Question

我在 UIView 上有一个按钮，我想在单击按钮时初始化一个 UIViewcontroller。我试图在单击按钮时显示另一个 ViewController 但出现错误:

reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key AboutUser.'

// 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()
    }
}

Answer 1

原因:“[setValue:forUndefinedKey:]:此类与键 AboutUser 的键值编码不兼容。”

回复:可能是你从另一个 Controller 复制粘贴按钮请删除该类的操作并为该类提供操作
