在你访问照相机、通讯录、等等隐私以及敏感数据之前，你必须请求授权。否则你的app会在你尝试访问这些隐私时崩溃。Xcode会log这些：
This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app’s Info.plist must contain an NSContactsUsageDescription key with a string value explaining to the user how the app uses this data.
打开你工程中名叫 info.plist 的文件，右键点击选择 opening as Source Code，把下面的代码粘贴进去。或者你可以使用默认的 Property List 打开 info.plist，点击add按钮，当你输入 Privacy - Xcode会给你自动补全的建议，用上下键去选择吧。
私有数据的框架列表可是个不小的东西:
