I decided to use InAppSettingsKit for my app. However, certain settings require the user to use the audio input for custom setting. I was wondering whether there is a way of presenting a modal view controller from within Settings.bundle - getting the parent view controller that presents Settings.app to sense that a button/setting was changed and launch another view controller on top of this one to pick the new setting from audio input and pass it on to the setting.bundle?

InAppSettingsKit 带有一个扩展，允许您执行此操作。

检查自述文件中的自定义视图控制器部分。当然，这只适用于应用程序，而不是设置应用程序。有几个选项可以区分 Settings.app 和应用内的设置列表。请参阅“自定义应用程序列表”。

Settings.bundle 和您打开的应用程序之间没有默认的通信机制。他们可以在彼此之间传递数据的唯一方法是通过 NSUserDefaults。

如果您愿意，您可以将值存储到 NSUserDefaults 中以指示您打开的最后一个 View Controller，但这必须是手动过程。即使实现了这一点，Settings.bundle 中也没有地方可以执行逻辑来消耗该值。
