ios - Swift - How can I send a notification when AVPlayer gets overridden in the background mode? -

my app continues play music when app in background , hoping send user notification when avplayer gets overridden (e.g. if user uses app on rides it).

currently solution use checkintimer sets notification , if app not checkin after x amount of time, notification goes off, if checkin deletes notification , sets one. solution sucks..

any ideas?

you need observe audio interruptions:

import avfoundation  func setup() {     nsnotificationcenter.defaultcenter().addobserver(self, selector: #selector(myinterruptionhandler), name: avaudiosessioninterruptionnotification, object: nil) }  func myinterruptionhandler(notification: nsnotification) {     var info = notification.userinfo!     var intvalue: uint = 0     (info[avaudiosessioninterruptiontypekey] as! nsvalue).getvalue(&intvalue)     if let type = avaudiosessioninterruptiontype(rawvalue: intvalue) {         switch type {         case .began:             // interruption began         case .ended:             // interruption ended         }     } }
