We are a music app, encountered a scene, there is no way to resume playing music, so I would like to ask about the technical plan, how to achieve it. For example, when playing a video in another app, we pause the music playing and turn off the video, we should resume the music playing.
Our code is implemented, so listen AVAudioSessionInterruptionNotification, when we received the notice and judge AVAudioSessionInterruptionOptionShouldResume, we play music came again, Error 560557684（AVAudioSessionErrorCodeCannotInterruptOthers） was reported. We were very confused
NSError *error = nil;
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
[audioSession setCategory:AVAudioSessionCategoryPlayback withOptions:0 error:&error];
[audioSession setActive:YES error:&error];
We compared the apple music app and found that apple music can resume playing.
Here is a video of the effects of our app: https://drive.google.com/file/d/1J94S2kxkEpNvG536yzCnKmE7IN3cGzIJ/view?usp=sharing

We want to improve our user experience. How can we do that?
