未设置相应权限，使用相机会闪退
项目打印提示：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.
相应权限需要开发者手动添加
直接在info里的bundle name标签上点+号，输入Privacy就会出现相应的，按照项目需求，添加相应的即可
