Ios 本地通知声音不起作用

我有一个应用程序，可以发出带有声音的本地通知

但当通知触发时，如果我的应用程序正在运行，它不会播放声音。只有当我关闭应用程序时，它才会播放通知声音

我希望它能够播放声音，即使应用程序正在手机上运行

这是我的密码：

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)

有什么帮助吗？

您必须使用didReceiveLocalNotification手动播放声音

我可以在这里播放默认的通知声音吗？您不能@mikle94您必须添加自定义声音

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()
}
