不工作的本地通知声音 [英] Local notification sound not working

问题描述

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
}
