在Mac上使用Swift显示通知横幅

问题描述

我试图在使用Swift的Mac OS上显示一些通知横幅.但我只在通知中心看到它们，而不是横幅.

I tried to show up some notification banners on Mac OS with Swift. But i get them only in the notification center, not as banner.

您有个主意吗?这是我的简单代码:

Do you have an idea? Here my simple code:

func showNotification() -> Void {
    let notification = NSUserNotification()
    notification.title = "Title of notification"
    notification.subtitle = "Subtitle of notification"
    notification.soundName = NSUserNotificationDefaultSoundName
    NSUserNotificationCenter.default.deliver(notification) 
}

@IBAction func btnPressed(_ sender: NSButton) {
    showNotification()
    testLbl.stringValue = "Button was pressed"
}

推荐答案

如果您的应用程序位于前台，则不会显示标题.

You won't get a banner if your app is in the foreground.

尝试使用…

notification.deliveryDate = Date(timeIntervalSinceNow: 5)
NSUserNotificationCenter.default.scheduleNotification(notification)

然后切换到另一个应用
