<blockquote>
<p>I'd like to hide the <strong>system volume HUD</strong>while adjusting the volume programmately without the need of a loaded View.</p>

<strong>所以这个解决方案不是我想要的(在我的情况下这是 Not Acceptable ):</strong></p>
<pre><code>let volumeView = MPVolumeView(frame: .zero)
view.addSubview(volumeView)
</code></pre>
<hr/>
<p>我想要一个工作函数来隐藏volumeView，同时避免添加隐藏的Subview。</p>
<p>这是我到目前为止所得到的(但是目前这不起作用):</p>
<pre><code>func hideHUD() {
let volumeWindow: UIWindow = UIWindow()
let volumeView = MPVolumeView(frame: .zero)
volumeView.isHidden = false
volumeWindow.isHidden = true
volumeWindow.addSubview(volumeView)
}
</code></pre>
<p><strong>注意:</strong>我很确定可以通过编程方式隐藏音量 HUD，因为 <em>VolumeBar API</em> (<a href="https://github.com/gizmosachin/VolumeBar/blob/master/Sources/VolumeBar.swift" rel="noreferrer noopener nofollow">you can find here</a>) 能够隐藏 HUD 并替换有自己的风格!</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>您想要的似乎不可能。您链接的 <em>VolumeBar</em> 项目使用不可见的 MPVolumeView 来隐藏系统 HUD，就像其他人建议的那样。 <a href="https://github.com/gizmosachin/VolumeBar/blob/f8bd5311bc1e90a071836718bd5da220fdb54a38/Sources/Internal/VolumeBarWindow.swift#L40" rel="noreferrer noopener nofollow">See here</a> </p>
<pre><code>/// A standard iOS `MPVolumeView` that never appears but is necessary to hide the system volume HUD.
private let systemVolumeView: MPVolumeView
</code></pre>
<p>...</p>
<pre><code>// Add a non-hidden MPVolumeView with a zero frame to prevent the system volume HUD from showing
systemVolumeView = MPVolumeView(frame: .zero)
systemVolumeView.isHidden = false
systemVolumeView.clipsToBounds = true
systemVolumeView.showsRouteButton = false
systemVolumeView.alpha = 0.0001
</code></pre>
