iOS10系統下調用系統相冊、相機功能，遇到閃退的情況，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.

在info.plist文件下添加

這是因為iOS對用戶的安全和隱私的增強,在申請很多私有權限的時候都需要添加描述,但是,在使用Xcode 8之前的Xcode還是使用系統的權限通知框.
要想解決這個問題,只需要在info.plist添加NSContactsUsageDescription的key, value自己隨意填寫就可以,這里列舉出對應的key(Source Code模式下):

 <key>NSCameraUsageDescription</key>    
    <string>cameraDesciption</string>

    <key>NSContactsUsageDescription</key>    
    <string>contactsDesciption</string>

    <key>NSMicrophoneUsageDescription</key>    
    <string>microphoneDesciption</string>
