macos - Swift NSUserNotificationCenter didActivateNotification 不工作

Question

我正在开发一个 swift os x 应用程序，但我无法理解 userNoticiation/didActivateNotification 结构。我已经查看了文档并进行了搜索，但仍然卡住了。非常感谢对以下代码的任何指导:

func notify(message: String, callBack: String) {


    println(message)
    println(callBack)
    var notification:NSUserNotification = NSUserNotification()
    notification.title = "New Phone Call"
    notification.informativeText = message
    notification.actionButtonTitle = "Lookup"
    notification.hasActionButton = true
    var center:NSUserNotificationCenter = NSUserNotificationCenter.defaultUserNotificationCenter()


    center.delegate = self
    center.scheduleNotification(notification)



}
func notify (center: NSUserNotificationCenter, didActivateNotification notification: NSUserNotification){
    center.delegate = self
    println("clicked")  //this does not print
}

通知显示完全符合我的意愿。单击我定义的“查找”按钮会在第一次单击时将我的应用程序带到前台，但我希望处理该操作的代码不会触发。

提前致谢。

将您的第二个“func notify”声明更改为“optional func userNotificationCenter”
