背景：
Apple 为他们的 iPad 提供了一种“kiosk 模式”，作为 iOS6 的一部分，它将设备锁定在一个应用程序中（甚至直接启动到应用程序中）。非常适合在零售/餐厅/等场所使用 iPad。
为了使用它，首先必须使用 Apple Configurator 将设备设置为“受监督”设备。然后，您将一个特殊条目添加到名为“App Lock”的配置文件中。我遵循了最近更新的配置文件文档。本质上，您只需将 PayloadType 设置为“com.apple.app.lock”并添加一个名为“Identifier”的属性，该属性设置为应用程序包 ID 的值。
当我尝试将配置文件添加到 iPad 时（无论是通过 Safari 链接、MDM 还是 Apple Configurator），它都会拒绝它。
Xcode 中的控制台输出显示如下：
