本地通知聲音不起作用

Question

我有一個可以發出聲音的本地通知的應用程序。

但是，當觸發通知時，如果我的應用程序正在運行，則不會播放聲音。 只有當我關閉我的應用程序時，它才會播放通知聲音。

我希望它即使在手機上運行應用程序也能播放聲音。

這是我的代碼：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    // register for sending notifications
    let notificationType = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound
    let settings = UIUserNotificationSettings(forTypes: notificationType, categories: nil)
    application.registerUserNotificationSettings(settings)

    return true
}

var localNotification:UILocalNotification = UILocalNotification()
localNotification.alertAction = "Testing notifications on iOS8"
localNotification.alertBody = "Local notifications are working"
localNotification.fireDate = NSDate(timeIntervalSinceNow: 1)
localNotification.soundName = UILocalNotificationDefaultSoundName
UIApplication.sharedApplication().scheduleLocalNotification(localNotification)

有什么幫助嗎？

您必須使用didReceiveLocalNotification手動播放聲音

func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) {
 print("received local notification")

 application.applicationIconBadgeNumber = 0

 //Play sound
 let soundURL = NSBundle.mainBundle().URLForResource("beep", withExtension: "wav")
 var mySound: SystemSoundID = 0
 AudioServicesCreateSystemSoundID(soundURL, &mySound)
 AudioServicesPlaySystemSound(mySound)

 var alert = UIAlertView()
 alert.title = "Alert"
 alert.message = notification.alertBody
 alert.addButtonWithTitle("Dismiss")

 alert.show()
}
