即使定义了 key NSPhotoLibraryUsageDescription，访问 iPhone 照片库时 iOS 应用程序也会崩溃

Question

我有一个正在更新到 Xcode 8.2.1 的应用程序。以前访问相机和照片库工作正常。但是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 键添加到您的 info.plist”。

但我做过这样的事!我的应用程序仍然崩溃!

我的 info.plist 文件:

<key>NSLocationWhenInUseUsageDescription</key>
<string>Permet à l'application de connaitre l&apos;emplacement de vos posts</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>$(PRODUCT_NAME) uses photos</string>
<key>NSCameraUsageDescription</key>
<string>$(PRODUCT_NAME) uses camera</string>
<key>CFBundleDevelopmentRegion</key>

代码主要基于一个苹果的例子...

- (IBAction)showImagePickerForPhotoPicker:(id)sender
{
    [self showImagePickerForSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
}
- (void)showImagePickerForSourceType:(UIImagePickerControllerSourceType)sourceType
{
    // ...
    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
    imagePickerController.sourceType = sourceType;
    imagePickerController.delegate = self;

    if (sourceType == UIImagePickerControllerSourceTypeCamera)
    {
    // ..
    }

    self.imagePickerController = imagePickerController;
    [self presentViewController:self.imagePickerController animated:YES completion:nil];
}

好吧，我真的卡住了......也许是项目配置问题？

我很抱歉，但这是我的错，在迁移时我弄乱了 info.plist 文件。
