大约一个月前，我在xcode上用cpp编写了一个程序，该程序使用Opencv打开了摄像机，并能够显示供稿。现在，当我运行它时，它会抛出[access] This app has crashed because it attempted to access privacy-sensitive
data without a usage description. The app's Info.plist must contain an
NSCameraUsageDescription key with a string value explaining to the
user how the app uses this data.
我认为唯一可以更改的是升级到Mac Mojave。这是错误的唯一来源，因为它以前曾经起作用过？或者我的项目中是否有其他原因导致此现象现在出现？
最佳答案
If you link on or after iOS 10, or on or after macOS 10.14, your app crashes if you try to access certain protected resources without providing a corresponding purpose string. Even if it’s not required, it’s always best to provide a usage string if your app uses a protected resource.
