推荐答案

你需要像这样放置音量叠加：

You need to put volume overlay like this:

MPVolumeView *volumeView = [[MPVolumeView alloc] initWithFrame: CGRectZero];
[self.view addSubview: volumeView];

现在自定义叠加层将不可见。但请记住，您无法按下音量按钮，只能通知其效果 - 更改音量

Now the custom overlay won't be visible. But keep in mind that you are not able to get action on pressing volume buttons you can only be notified about its effect - changing a volume
