swift - macOS 中的 NSUserNotificationCenter

Question

我正在尝试创建一个会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"is"、“否”或单击通知时，我尝试执行代码。我尝试改用这个函数:

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

但是当我使用它时，通知没有显示。

我找到了一种方法，当使用这两个功能时，当用户单击它时，我可以弹出通知。

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;
    }
}
