访问iPhone照片库时iOS应用程序崩溃，即使定义了关键的NSPhotoLibraryUsageDescription

Question

我有一个应用程序，我正在更新到 Xcode 8.2.1。以前，对相机和照片库的访问工作正常。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.

堆栈溢出上的许多帖子只是说"添加NSPhotoLibraryUsageDescription密钥"到您的info.plist。

但是我做过这样的事情！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>

该代码主要基于苹果示例...

- (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，我真的被困住了...也许是项目配置问题？

我很

抱歉，但这是我的错，在迁移时，我对info.plist文件造成了一些混乱。
