从UINavigationController视图堆栈中取消显示的UIImagePickerController

Question

考虑以下视图控制器层次结构：

UIViewController (root)
   - present: UINavigationController
       - push: UIViewController A
       - push: UIViewController B
           - present: UIImagePickerController

当关闭UIImagePickerController时，UINavigationController弹出其根视图控制器（A）。

这是要显示的代码：

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.modalPresentationStyle = UIModalPresentationFullScreen;
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePickerController.mediaTypes = @[ (NSString *)kUTTypeImage ];
imagePickerController.delegate = self;

[self presentViewController: imagePickerController
                   animated: YES
                 completion: nil];

我已经尝试了各种方案和目标，以提供具有相同最终结果的视图控制器。 在UIImagePickerController关闭之前/之后保存/还原viewController堆栈会导致不良的视图过渡。

有没有办法做到这一点？

只要您使用UIModalPresentationOverFullScreen modalPresentationStyle，解除操作就起作用。

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.modalPresentationStyle = UIModalPresentationOverFullScreen;
imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePickerController.mediaTypes = @[ (NSString *)kUTTypeImage ];
imagePickerController.delegate = self;

[self presentViewController: imagePickerController
                   animated: YES
                 completion: nil];
