iOS应用程序在访问iPhone照片库时崩溃，即使已定义密钥NSPhotoLibraryUsageDescription

我有一个正在更新到Xcode 8.2.1的应用程序。以前，对相机和照片库的访问正常。但现在应用程序崩溃，并显示以下消息：

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.

stackoverflow上的许多帖子只是说将NSPhotoLibraryUsageDescription密钥添加到info.plist

但我做过这样的事！ 我的应用程序仍然崩溃

My info.plist文件：

---

嗯，我真的被卡住了。。。可能是项目配置问题

我很抱歉，但这是我的错，迁移时我弄乱了info.plist文件。

尝试清理您的项目，如果仍然不起作用，请删除应用程序并重新安装。即使这两项都不起作用，请转到“设置”并重置设备的隐私设置。清理项目，删除应用程序并重新安装。不起作用…如何重置隐私设置？您可以尝试删除$PRODUCT\U NAME并重试。设置>常规>重置>重置位置和隐私。对我来说，我将NSCameraUsageDescription添加到单元测试中，而不是主程序中。我想所有的路都会导致iOS应用程序崩溃。
