AppDelegate:

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?
    
    public static let shared = AppDelegate()

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        
        /// 初始化通知，初始化其他通知组件
        initCloudPush(launchOptions)
        
        /// Other Code
        return true
    }
 }

在其他地方，准备提示申请权限的时候调用：

    AppDelegate.shared.registerNotification()
