Ios EXC\u错误\u访问内核\u无效\u地址

在上两个版本中，我们收到了太多与CFNetwork和EXC_BAD_ACCESS KERN_INVALID_ADDRESS相关的崩溃。因此，我们试图找出问题所在，并启用了NSZombie，并通过调试内存图进行验证。我们在下面的图片上得到了一个紫色的警告

在以编程方式创建一个按钮（如下图所示）时是否存在任何问题，并为另一个图像问题提供一些指针

class CustomButton{

    var didTab: (() -> Void)?


    private let button  :UIButton
    init(text: String,fontSize: CGFloat) {
        button = UIButton()
        button.setTitle(text, for: .normal)
        button.titleLabel?.font = UIFont (name: "MuseoSans-500", size: fontSize)
        button.translatesAutoresizingMaskIntoConstraints = false
        button.addTarget(self, action: #selector(_didTabButton), for: .touchUpInside)
    }

    func setImage(_ image: UIImage?) -> Self{
        button.setImage(image, for: .normal)
        return self
    }

    func setTitleColor(_ color:UIColor, _ state: UIControl.State)-> Self{
        button.setTitleColor(color, for: state)
        return self
    }
    func addTarget(target: Any?, action: Selector, fors:  UIControl.Event) -> Self{
        button.addTarget(target, action: action, for: fors)
        return self
    }

    func isHidden(bool: Bool)-> Self{
        button.isHidden = bool
        return self
    }

    func changeColor(color:UIColor) -> Self{
        button.backgroundColor = color
        return self
    }

    func buildUI() -> UIButton{
        return button
    }

    @objc
    private func _didTabButton() {
        didTab?()
    }
}

控制器：

let notificationButton = CustomButton(text: "", fontSize: 20)
    .setImage(UIImage(named:"notification"))
    .addTarget(target: self, action: #selector(notificationList), fors: .touchUpInside)
    .buildUI()


func setUpView(){
    view.addSubview(notificationButton)
}
func setUpConstrainsts(){
    //notificationButton
    notificationButton.topAnchor.constraint(equalTo: view.topAnchor, constant: 10).isActive = true
    notificationButton.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 5).isActive = true
    notificationButton.widthAnchor.constraint(equalToConstant: 40).isActive = true
    notificationButton.heightAnchor.constraint(equalToConstant: 40).isActive = true

您没有为您的按钮提供任何框架。我们已通过编程方式添加了约束，并且按钮按预期工作。
