我试图做出正确的报警程序，但是当我尝试做一个本地通知我无法播放声音。我得到这个错误：

[用户信息=（空）}具有健全的，但还没有收到许可用户播放声音]

下面是code：

@IBOutlet VAR setAlaram：的UIDatePicker！@IBAction FUNC setAlarmButton（发件人：AnyObject）{    VAR dateformater = NSDateFormatter（）    dateformater.timeZone = NSTimeZone .defaultTimeZone（）    dateformater.timeStyle = NSDateFormatterStyle.ShortStyle    dateformater.dateStyle = NSDateFormatterStyle.ShortStyle    VAR datetimestring =的NSString（）    datetimestring = dateformater.stringFromDate（setAlaram.date）    的println（datetimestring）    [自.localnotification（setAlaram.date）}FUNC localnotification（firedate：NSDate的）{    VAR localNotification：UILocalNotification = UILocalNotification（）    localNotification.fireDate = firedate    localNotification.alertBody =时间醒过来    localNotification.soundName =alarm.wav    UIApplication.sharedApplication（）。scheduleLocalNotification（localNotification）}覆盖FUNC viewDidLoad中（）{    super.viewDidLoad（）    让DATE1 = NSDate的（）    setAlaram.date = DATE1}

解决方案

您需要征得他的许可用户在iOS 8的发送本地通知。

您可以这样做，当你的AppDelegate方法，你的应用程序启动

FUNC应用程序（应用程序：UIApplication的，didFinishLaunchingWithOptions launchOptions：[NSObject的：AnyObject]） - GT;布尔{    application.registerUserNotificationSettings（UIUserNotificationSettings（forTypes：.Sound | .Alert | .Badge，类别：无））    返回true}

I'm trying to make an alarm app but when I try to make a local notification I am unable to play the sound. I got this error:

[user info = (null)} with a sound but haven't received permission from the user to play sounds]

Here is the code:

@IBOutlet var setAlaram: UIDatePicker! @IBAction func setAlarmButton(sender: AnyObject) { var dateformater = NSDateFormatter() dateformater.timeZone = NSTimeZone .defaultTimeZone() dateformater.timeStyle = NSDateFormatterStyle.ShortStyle dateformater.dateStyle = NSDateFormatterStyle.ShortStyle var datetimestring = NSString() datetimestring = dateformater.stringFromDate(setAlaram.date) println(datetimestring) [self .localnotification(setAlaram.date)] } func localnotification (firedate:NSDate) { var localNotification:UILocalNotification = UILocalNotification() localNotification.fireDate = firedate localNotification.alertBody = "time to woke up" localNotification.soundName = "alarm.wav" UIApplication.sharedApplication().scheduleLocalNotification(localNotification) } override func viewDidLoad() { super.viewDidLoad() let date1 = NSDate() setAlaram.date = date1 }

解决方案

You need to ask the user for permission to send local notifications in iOS 8.

You can do so when you application launches in your AppDelegate methods

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: .Sound | .Alert | .Badge, categories: nil)) return true }
