Swift NSUserNotificationCenter doActivateNotification无效

Question

我正在研究一个快速的os x应用程序,我无法理解userNoticiation/didActivateNotification结构.我查看了文档并搜索了SO但仍然卡住了.我们非常感谢您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要求.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,但是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'
