iOS10系统下调用系统相册、相机功能，或者苹果健康都会遇到闪退的情况，
调用系统相册报错描述如下
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
解决办法
在info.plist 根据需求添加
- 需要注意的是 描述性字符串是一定要写的，不然会引发包无效的问题，导致上传打包后构建版本一直不显示
