Xcode 9 GM 中有一个新的隐私 NSFaceIDUsageDescription Info.plist key ，开发人员在其中提供权限警报的使用说明。有没有人有关于它的文档的链接？ Xcode中的plist View 总结为:
Privacy - Face ID Usage Description
最佳答案
现在在上面提到的论坛中进一步解释(由 Apple 员工提供)https://forums.developer.apple.com/message/265156 :
Face ID requires adding a usage string with the key NSFaceIDUsageDescription (aka Privacy - Face ID Usage Description) to your app's Info.plist.
In the simulator, the Face ID permissions alert will show "This app was designed to use Touch ID and may not fully support Face ID" if that key is missing. On an actual device, your app will crash the same as if any other required usage string is missing.
关于ios - 什么是 NSFaceIDUsageDescription - Face ID Usage Description Info.plist key ？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/46309440/
