Answer 1

I encountered the same issue recently. Instead of adding the MPVolumeView to current view controller's view, I add it to the application's window once at the start of the app:

CGRect rect = CGRectMake(-500, -500, 0, 0);
MPVolumeView *volumeView = [[MPVolumeView alloc] initWithFrame:rect];
[self.window addSubview:volumeView];

This works in both iOS 7 and 8.
