swift - macOS中的NSUserNotificationCenter

我正在尝试创建一个将弹出通知的应用程序。
我在我的应用程序中使用NSUserNotificationCenterDelegate，如下所示：

class AppDelegate: NSObject, NSApplicationDelegate, NSUserNotificationCenterDelegate {
    let NScenter = NSUserNotificationCenter.default

    func applicationDidFinishLaunching(_ aNotification: Notification) {
        self.NScenter.delegate = self
        let notification = NSUserNotification.init();
        self.NScenter.deliver(notification)
    }

    func userNotificationCenter(_ center: NSUserNotificationCenter, shouldPresent notification: NSUserNotification) -> Bool {
        return true;
    }

当用户按“是”，“否”或单击通知时，我正在尝试执行代码。
我尝试改用此功能：

    func userNotificationCenter(_ center: NSUserNotificationCenter, didActivate notification: NSUserNotification) -> Bool {
        print("ok");
        return true;
    }

但是当我使用它时，通知只是没有出现。

最佳答案

我找到了一种方法，在同时使用这两个功能时，通知弹出窗口以及用户单击它时都可以得到。

class AppDelegate: NSObject, NSApplicationDelegate, NSUserNotificationCenterDelegate {
    let NScenter = NSUserNotificationCenter.default

    func applicationDidFinishLaunching(_ aNotification: Notification) {
        self.NScenter.delegate = self
        let notification = NSUserNotification.init();
        self.NScenter.deliver(notification)
    }

    func userNotificationCenter(_ center: NSUserNotificationCenter, shouldPresent notification: NSUserNotification) -> Bool {
        return true;
    }


    func userNotificationCenter(_ center: NSUserNotificationCenter, didActivate notification: NSUserNotification) -> Bool {
        print("ok");
        return true;
    }
}
