更改MPMusicPlayerController的音量而不更改系统音量

Question

My app has a feature to play system music player's music and it has it's own audio too. When music player's music is playing and app's audio will begin to play, I have to decrease the music player volume without affecting app's volume.

I am currently changing music player's volume with MPVolumeView as MPMusicPlayerController volume property is deprecated. But it is system volume which affects app's volume too though I have used [avAudioPlayer setVolume:1.0] , which is quite natural.

My question is, is there any way to change the music player's volume without affecting app's volume?

Answer 1

Yo can only change device volume with MPVolumeView . If you want to change application volume, there is AVAudioPlayer . It has volume property, so you can change your volume that way.
