iOS 10 UserNotifications custom sound in background mode

Question

Since UILocalNotification is deprecated in iOS 10 so I have updated my local notification flow using the UNUserNotification framework.

The app plays custom sound using AVPlayer when the app is in the foreground and it works fine. But in background mode when local notification is triggered, instead of custom sound, a default notification sound is being played.

However, things were working fine in iOS9, using "didReceiveLocalNotification" method app can play custom sound even in background mode.

Update 1:

I'm setting local notification as follows:

let content = UNMutableNotificationContent()
content.title = NSString.localizedUserNotificationStringForKey("reminder!", arguments: nil)
content.body = NSString.localizedUserNotificationStringForKey("Reminder body.", arguments: nil)
if let audioUrl == nil {
    content.sound = UNNotificationSound.defaultSound()
} else {
    let alertSound = NSURL(fileURLWithPath: self.selectedAudioFilePath)
    content.sound = UNNotificationSound(named: alertSound.lastPathComponent!)
}
content.userInfo = infoDic as [NSObject : AnyObject]
content.badge = 1
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 60, repeats: false)
let identifier = "Reminder-\(date)"
let request = UNNotificationRequest(identifier: identifier, content: content, trigger: trigger)
let center = UNUserNotificationCenter.currentNotificationCenter()
center.addNotificationRequest(request, withCompletionHandler: { (error) in
    if error != nil {
        print("local notification created successfully.")
    }
})

I have already gone through many SO Questions but didn't get the solution.

Any help will be greatly appreciated!

Solution 1

Found out that alertSound doesn't have the correct file path hence the content.sound sets nothing. I was saving the recorded file in documents directory and the file path retrieve for real device is different as compared to the simulator.

Setting a sound file which is placed in project bundle did the trick

content.sound = UNNotificationSound(named: "out.caf")

Solution 2

In Swift 4.2 and Xcode 10.1

For local notifications to play sound

let content = UNMutableNotificationContent()
content.title = "Notification Tutorial"
content.subtitle = "from ioscreator.com"
content.body = " Notification triggered"
//Default sound
content.sound = UNNotificationSound.default
//Play custom sound
content.sound = UNNotificationSound(named:UNNotificationSoundName(rawValue: "123.mp3"))

"123.mp3" file needs to be in your Bundle.

Thanks for your kind reply. But I'm using LocalNotification not push/remote. My app records a sound and save it and then fire a local notification that should be played in background mode. thanks

Yes, that's fine. It would work if the app is in foreground. In background mode you will probably have the same issue mentioned in 4) as the path you stored the downloaded file will be different that Bundle.main

For me it does not work with .mp3 files. But it works with .caf files. Luckily, there are numerous online converters for that.
