iOS Swift本地通知没有声音

Question

Iam trying to make a regular UILocalNotification with default sound

this is my function

func makeLocalNotificationForNow(str : String , id : String)
{
let notification = UILocalNotification()


notification.alertBody = str // text that will be displayed in the notification
notification.alertAction = "open" // text that is displayed after "slide to..." on the lock screen - defaults to "slide to view"
notification.fireDate = NSDate(timeIntervalSinceNow: 5) // todo item due date (when notification will be fired)
notification.soundName = UILocalNotificationDefaultSoundName // play default sound
UIApplication.sharedApplication().scheduleLocalNotification(notification)
}

in my didFinishLaunchingWithOptions function I put

let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge , .Sound], categories: nil)
            application.registerUserNotificationSettings(settings)
            application.registerForRemoteNotifications()

Note : I also use parse push notifications

when I make the notification , it appears but without an alert or sound (I need to swipe the from top to see the notification what's wrong ?!

据我所知，只有当应用程序在后台运行时，通知才会发出声音，这意味着退出应用程序，将手机置于锁定模式，并通过解析网站发送通知，那么您应该听到声音，如果没有，请检查在您正在执行的应用程序上进行设置，以查看是否启用了声音警报以及最新资源，请检查您的手机不是仅振动

这是一个愚蠢的错误，问题出在我的手机上，我换了手机，一切正常
