Ios 在委托方法中传递的类对象变为<；未初始化>；在Mac催化剂中

在实现协议的类中，委托方法中传递的对象未初始化。但同一对象在从中调用委托的类中具有有效地址。只有在maccatalyst中才会出现这种情况，同样的代码在iOS和iPadOS中也能完美运行

议定书声明

 protocol ASPatientSearchDelegate: class {
    func moveToPaitentProfileScreen(patient: ASCardEntity)
}

    weak var delegate: ASPatientSearchDelegate? = nil

class ASAppointmentViewController: ASBaseViewController {
    var searchViewController: ASPatientSearchViewController?
}

委托变量声明

 protocol ASPatientSearchDelegate: class {
    func moveToPaitentProfileScreen(patient: ASCardEntity)
}

    weak var delegate: ASPatientSearchDelegate? = nil

class ASAppointmentViewController: ASBaseViewController {
    var searchViewController: ASPatientSearchViewController?
}

代理调用

    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
            let patient = self.searchResults[indexPath.row]

                self.delegate?.moveToPaitentProfileScreen(patient: patient)
}

方法实现

extension ASAppointmentViewController: ASPatientSearchDelegate {
        func moveToPaitentProfileScreen(patient: ASCardEntity) {
    
            guard let json = patient.details as? JSON else { return }
    }
}

在ASAppointmentViewController中分配的代理

   @IBAction func searchButtonAction(_ sender: UIButton) {

        let searchViewController = ASPatientSearchViewController(nibName: ASPatientSearchViewController.className, bundle: nil)

        searchViewController.popoverPresentationController?.delegate = self
        searchViewController.modelController.delegate = self
}

使用的类

class ASCardEntity: NSObject {
    var details: Any?
}

---

这是实例范围问题。我已将ASPatientSearchViewController实例变量声明为类范围

实例变量声明

 protocol ASPatientSearchDelegate: class {
    func moveToPaitentProfileScreen(patient: ASCardEntity)
}

    weak var delegate: ASPatientSearchDelegate? = nil

class ASAppointmentViewController: ASBaseViewController {
    var searchViewController: ASPatientSearchViewController?
}

我改了下面的代码

@IBAction func searchButtonAction(_ sender: UIButton) {

        let searchViewController = ASPatientSearchViewController(nibName: ASPatientSearchViewController.className, bundle: nil)

        searchViewController.popoverPresentationController?.delegate = self
        searchViewController.modelController.delegate = self
}
