I'm developing an app that switches music using a MPMusicPlayerController.systemMusicPlayer() from the MPMedia framework. I need the song to change anywhere between 30 seconds and 1 minute for up to 100 minutes when the app is in the background. In the foreground of course everything works exactly how it should but in the background I can get the app to do this for about 3 minutes which seems to be the limit imposed on background tasks in iOS8. Is there a way to extend the allowable time that app can operate in the background?
I'm currently using the following code to register the background task where background_task is of type :
var background_task: UIBackgroundTaskIdentifier = UIBackgroundTaskInvalid
func registerBackgroundTask()
{
println("Background task registered")
background_task = UIApplication.sharedApplication().beginBackgroundTaskWithExpirationHandler
{
[unowned self] in
self.endBackgroundTask()
}
}
and then this ends it:
func endBackgroundTask()
{
NSLog("Background task ended.")
UIApplication.sharedApplication().endBackgroundTask(background_task)
background_task = UIBackgroundTaskInvalid
}
