我正在尝试制作一个闹钟应用程序，但是当我尝试制作一个本地通知时，我无法播放声音。我收到这个错误:
[user info = (null)} 有声音但没有收到用户播放声音的许可]
代码如下:
@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
}
最佳答案
在 iOS 8 中，您需要请求用户允许发送本地通知。
您可以在 AppDelegate 方法中启动应用程序时执行此操作
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: .Sound | .Alert | .Badge, categories: nil))
return true
}
关于ios - 本地通知声音不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26734350/
