ios - 无法将类型 'UIViewController.Type' 的值转换为预期的参数类型“UIViewController”

Question

此代码显示错误:“无法将‘UIViewController.Type’类型的值转换为预期的参数类型‘UIViewController’”。请告诉我如何解决这个问题。

@objc static func listBtn()
    {
        drawerVw = DrawerView(aryControllers: DrawerArray.array, isBlurEffect: true, isHeaderInTop: false, controller: UIViewController.self)
        //drawerVw = DrawerView(aryControllers: DrawerArray.array, isBlurEffect: true, isHeaderInTop: false, controller: self)
        drawerVw.delegate = UIViewController.self as? DrawerControllerDelegate
        //drawerVw.delegate = self
        drawerVw.changeUserName(name: "New Delhi")
        drawerVw.show()
    }

Answer 1

您需要使用此代码。这段代码在我这边工作得很好。

类

@objc static func listBtn() {
        UIViewController.showListButton(navigationController: navController)
}

扩展

import Foundation
import UIKit

extension UIViewController
{
    static func showListButton(navigationController: UINavigationController)
    {
        if let currentVC = navigationController.visibleViewController
        {
            drawerVw = DrawerView(aryControllers: DrawerArray.array, isBlurEffect: true, isHeaderInTop: false, controller: currentVC)
            drawerVw.delegate = currentVC as? DrawerControllerDelegate
            drawerVw.show()
        }
    }
}
