Background notifications from Spotify to my app(in background) using Spotify iOS SDK

[joshehrlich24]

Is there a way to receive playerStateDidChange notifications from Spotify while my app is in the background (I am happy to add whatever iOS background mode, if necessary). The goal is for my app to stay in sync with Spotify when a user changes the song through Spotify and not my app.

I am getting notified of events via playerStateDidChange when my app is in the foreground.

@joshehrlich24 there is a stub in SPTAppRemoteDelegate methods called appRemoteDidEstablishConnection, in which all UI updates could be done, according to the screen where you will arrive after switching from the native Spotify app. I can assure you that this method will be called whenever your app will come back from the background, because SPTAppRemote disconnects when you switch to another app and yours will enter this state (in this case, the stub appRemoteDidDisconnectWithError will be called) and attempting to connect when entering foreground (is the Spotify app is running and playing music of course, otherwise you have to wake it up using authorizeAndPlayURI method).
