Yep. My understanding may be incorrect, but I think MPVolumeView controls the system volume. People have apparently found ways to bring the window up and use fake touches to alter the system volume programmatically, but because it controls the overall volume of all apps you switch to and the next app you run, I think making use of these tricks would upset users.

I’m unfamiiar with programming this task, but a quick trawl through the docs led me to MPVolumeView, which seems to the current approach to handling playback volume on iOS. —Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
