运行时报错如下：

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.

这是因为iOS10之后权限的问题导致崩溃。

解决方法：在项目中找到info.plist文件，右击有个 Open As，以Source Code 的形式打开，如图

打开后添加权限代码就可以了，添加什么权限代码可查看报错日志，里面说缺少NSPhotoLibraryUsageDescription这个权限添加如下代码既可以了,以后此类问题都可以这样解决。

<key>NSPhotoLibraryUsageDescription</key>

<string>photoLibraryUsageDescription</string>

下面其他的部分权限代码。

<key>NSMicrophoneUsageDescription</key>

<string>microphoneDesciption</string>

<key>NSCameraUsageDescription</key>

<string>cameraDesciption</string>

<key>NSPhotoLibraryUsageDescription</key>

<string>photoLibraryDesciption</string>
