ios - NativeScript 扩展了 UNUserNotificationCenter 委托(delegate)

Question

我正在尝试扩展 UNUserNotificationCenter 的委托(delegate)。根据 Apple 文档，这必须在 didFinishLaunchingWithOptions 中完成。 ( https://developer.apple.com/reference/usernotifications/unusernotificationcenterdelegate )

关于如何让代码在应用程序的这一部分运行的文档已经存在。但是，我有点不确定我是否理解其工作原理的语义。在这里，我尝试扩展 UNUserNotificationCenterDelegate 并将其分配给当前的中心委托(delegate)属性，但是当我收到本地通知时，这两个函数都没有运行:

if (application.ios) {


    var __extends = this.__extends || function (d, b) {
        for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p];
        function __() { this.constructor = d; }
        __.prototype = b.prototype;
        d.prototype = new __();
    };

    var appDelegate = (function (_super, _notiCenter) {
       __extends(appDelegate, _super);

       function appDelegate() {
           _super.apply(this, arguments);
       }

       function UNUserNotificationCenterDelegate(){
           _notiCenter.apply(this, arguments);
       }    

       appDelegate.prototype.applicationDidFinishLaunchingWithOptions = function (application, launchOptions) {

       UNUserNotificationCenterDelegate.prototype.userNotificationCenterDidReceiveNotificationResponseWithCompletionHandler = function(center, notif, completion){
                console.log('We are here');
            }

            UNUserNotificationCenterDelegate.prototype.userNotificationCenterWillPresentNotificationWithCompletionHandler = function(center, notif, completion){
                console.log('We are here 2');   
            }      

            var center = utils.ios.getter(UNUserNotificationCenter, UNUserNotificationCenter.currentNotificationCenter);

            center.delegate = UNUserNotificationCenterDelegate;   

       };


       appDelegate.ObjCProtocols = [UIApplicationDelegate];
       return appDelegate;

    })(UIResponder, UNUserNotificationCenterDelegate);

   application.ios.delegate = appDelegate;

}

正确的做法如下，将 USUserNotificationCenterDelegate 添加到 appDelegate.ObjCProtocols 数组中:

if (application.ios) {

    var __extends = this.__extends || function (d, b) {
        for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p];
        function __() { this.constructor = d; }
        __.prototype = b.prototype;
        d.prototype = new __();
    };

    var appDelegate = (function (_super ) {

        __extends(appDelegate, _super);

        function appDelegate() {
            _super.apply(this, arguments);
        }

        appDelegate.prototype.userNotificationCenterDidReceiveNotificationResponseWithCompletionHandler = function(center, notif, completion){
            completion();
        }

        appDelegate.prototype.userNotificationCenterWillPresentNotificationWithCompletionHandler = function(center, notif, completion){
            completion(4);  
        }    

        appDelegate.prototype.applicationDidFinishLaunchingWithOptions = function (application, launchOptions) {

            var center = utils.ios.getter(UNUserNotificationCenter, UNUserNotificationCenter.currentNotificationCenter);
            center.delegate = this; 

        };

        appDelegate.ObjCProtocols = [UIApplicationDelegate, UNUserNotificationCenterDelegate];
        return appDelegate;

    })(UIResponder);

    application.ios.delegate = appDelegate;

}
