ios - 在 UIImagePickerController 之上呈现一个 View Controller ，而不是关闭 UIImagePickerController

Question

我正在开发一个应用程序，我必须使用图像选择器 Controller 从手机库导入图像。问题是我必须首先关闭选择器 Controller ，然后在选择器 Controller 关闭后呈现另一个 Controller 。有没有一种方法可以让我不必关闭图像选择器 Controller ，而是呈现 View Controller 或导航 Controller 。顺便说一句，如果我不关闭 imagePickerController，它就会崩溃。其次，我将展示一个传递所选图像的 View Controller 。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

你不能从同一个 vc 中呈现 2 个 vc ，所以要么

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

或

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