错误情况:

iOS10之后，使用Xcode 进行真机测试时，涉及设备权限使用的时候，会出现crash的情况：

| 调用照片库权限 |

 [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 NSPhotoLibraryUsageDescription key with a string value explaining to the user how the app uses this data. |

| 调用相机权限 |

[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.|

| 调用麦克风权限 |

 [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 NSMicrophoneUsageDescription key with a string value explaining to the user how the app uses this data.|

解决:

需要使用某一权限时，在Info.plist里面添加一个String字段即可：

所需权限	相应字段
相机权限	NSCameraUsageDescription
照片库权限	NSPhotoLibraryUsageDescription
麦克风权限	NSMicrophoneUsageDescription
定位权限(始终)	NSLocationAlwaysUsageDescription
定位问题(使用应用期间)	NSLocationWhenInUseUsageDescription

以上是部分示例，其他权限，在Info.plist文件中，添加一栏：输入 “Privacy - ”自动列出供选择
Privacy - Camera Usage Description
Privacy - Photo Library Usage Description
Privacy - Calendars Usage Description
…

配置完成后，进入APP，使用相应功能时，系统会弹窗提示使用相关权限。

End。
