從模態ViewController呈現UIImagePickerController

Question

在我的故事板中包含以下部分：

所以我想從UserProfileController中獲取：UIViewController“Мойпрофиль”，它是模態的（在圖像的頂部）UIImageViewController。

我的代碼：

extension UserProfileController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
    @IBAction func imagePressed(_ sender: Any) {
        let imagePickerController = UIImagePickerController()
        imagePickerController.delegate = self
        self.present(imagePickerController, animated: true, completion: nil)
    }

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        guard let image = info[UIImagePickerControllerOriginalImage] as? UIImage else {
            return
        }
        picker.dismiss(animated: true, completion: nil)
        userProfileImageView.image = image
    }
}

好了，出現了imagePickerController，但是選擇圖像后，我已經關閉了這兩個控制器（imagePickerController和父級-UserProfileControler）。

我究竟做錯了什么？ 謝謝

PS可能是問題，我正在顯示“ SideMenuNavigationController”為模態？ （因此在SideMenu框架文檔中建議）

嘗試在您的類中創建UIImagePickerController引用（作為變量）

// to choose an image from the Camera Roll
    fileprivate lazy var imagePicker: UIImagePickerController = {
        let picker: UIImagePickerController = UIImagePickerController()

        picker.allowsEditing = false
        picker.sourceType = .savedPhotosAlbum
        picker.delegate = self

        return picker
    }()
