在 UIImagePickerController 之上呈现一个视图控制器，而不是关闭 UIImagePickerController

Question

我正在开发一个应用程序，我必须在其中使用图像选择器控制器从 phone 的库中导入图像。问题是我必须首先关闭选择器控制器，然后在选择器控制器关闭后呈现另一个控制器。有没有一种方法我不必关闭图像选择器控制器，而是呈现一个视图控制器或一个导航控制器。顺便说一句，如果我不关闭 imagePickerController，它就会崩溃。其次，我展示了一个视图控制器，它传递被选择的图像。谢谢。

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {

        let shViewController = SHViewController()

        if let editedImage = info[UIImagePickerController.InfoKey.editedImage] as? UIImage {
            shViewController.image = editedImage
        } else if let originalImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
            shViewController.image = originalImage
        }


        shViewController.delegate = self

        dismiss(animated: true, completion: nil)
        present(shViewController, animated: true, completion: nil)
    }

Answer 1

您不能从同一个 vc 中展示 2 vc，所以要么

picker.present(shViewController, animated: true, completion: nil)

或

dismiss(animated:false) {
   self.present(shViewController, animated: true, completion: nil)
}

在 UIImagePickerController 之上呈现一个视图控制器，而不是关闭 UIImagePickerController

Present a view controller on top of UIImagePickerController instead of dismissing the UIImagePickerController

viewcontroller
