Background When I receive the InterruptionBegan notification (the interruption type is AVAudioSessionInterruptionTypeBegan) , I pause playing music. When I receive the InterruptionEnded notification (the interruption type is AVAudioSessionInterruptionTypeEnded), I resume playing music. however, sometimes i has got the error code: AVAudioSessionErrorCodeCannotInterruptOthers (560557684) Some Solutions I searched stackoverflow, there's some similar questions, and some solutions here are not very satisfying as : I don't want my app to mix with others, and once again, it all works most of the time. My app already uses remote control events so this doesn't solve anything. Questions 1.Have someone ever encountered this problem ? 2.Can we solve this problem and how ? 3.In addition, I noticed that there's property named otherAudioPlaying in AVAudioSession, we can know there's another app is playing，the quetion is if we can know which app is playing ?
