iOS8 - UILocalNotification, Check for permission later from code

Question

I am writing my application in Swift for iOS8.

I wanted to use UILocalNotification to notify user of some things. For that, I have asked permission at the app launch with this:

application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Sound | UIUserNotificationType.Alert | UIUserNotificationType.Badge, categories: nil))

A confirm box shows up asking for permission. If user allows it, there's no problem.

If the user does not give permission, how do I check if local notifications are enabled from code (programmatically)?

Answer 1

..and this is how you check it in Swift:

let currentSettings = UIApplication.sharedApplication().currentUserNotificationSettings()
let required:UIUserNotificationType = UIUserNotificationType.Sound; // Add other permissions as required
let notification = UILocalNotification()

    if (currentSettings.types & required) != nil {
        println("sound will come and also vibration")
        notification.soundName = UILocalNotificationDefaultSoundName
    }else{
        println("no sound no vibration")
    }

Nice to know:
it will vibrate automatically, whether sound is on/off over your iphone button - nothing will happen if the user will set sound off in settings for your app.
So you don't have to add vibration additionally.
