ios - UIStatusBar 过渡动画——仅更改 Alpha

Question

我试图让 UIStatusBar 在过渡期间淡出，并在完成时淡入。 (这纯粹是风格上的——我有一个从顶部开始的过渡，至少对我来说，在 UIStatusBar 下看起来很刺耳)

有没有办法不删除 UIStatusBar 而只是让整个 view.layer.alpha = 0.0？

iOS9.2 和 Swift2

不要认为它可能 Apple 似乎正在插入基于状态栏控件的 View Controller 并贬低所有 api 以手动更改状态栏状态。我真的希望在下一次 WWDC 中他们会推出这些的替代品。由于需要更改状态栏颜色/样式的自定义转换，我在我的应用程序中面临同样的问题。
