iOS10调用系统相机、相册、麦克风、通讯录问题

在iOS10以后调用系统相机、相册，会报错，提示如下

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.

对于这个问题，我们需要在info.plist文件中加入以下代码 (ps:右键info -> open as -> Source Code)

• 相机权限

<key>NSCameraUsageDescription</key>

<string>cameraDesciption</string>

• 相册权限

<key>NSPhotoLibraryUsageDescription</key>

<string>photoLibraryDesciption</string>

• 通讯录权限

<key>NSContactsUsageDescription</key>

<string>contactsDesciption</string>

• 麦克风权限

<key>NSMicrophoneUsageDescription</key>

<string>microphoneDesciption</string>
