iOS10 UIImageWriteToSavedPhotosAlbum程序奔溃crash解决办法

Posted 2020-10-07 Sinner_Yun

Xcode报错:  

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.

解决方案
1.在项目中找到info.plist文件，右键点击以 Source Code形式打开
2.添加以下键值对，这里以 PhotoLibrary 作为例子

    <key>NSPhotoLibraryUsageDescription</key>
    <string>此 App 需要您的同意才能读取媒体资料库</string>

目测所有需要的权限描述都会在 ios 10 beta里面crash，不用怕，控制台会有输出的，自行添加就 OK，我另外附送几个 key/value 给你们

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

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

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

嗯，然后 clean 一下，重新运行。
