Question

有我故事板的这一部分：

git pull

所以我想要来自UserProfileController：UIViewController“Мойпрофиль”，这是模态的，（在图像的顶部）UIImageViewController。

我的代码：

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
    }
}

嗯，imagePickerController出现了，但是在我选择了图像后，我已经解散了两个控制器（imagePickerController和parent - UserProfileControler）。

我做错了什么？感谢

P.S。可能是问题是我将“SideMenuNavigationController”显示为模态？（在SideMenu框架文档中建议）

尝试在您的类中创建UIImagePickerController引用（作为变量）

// 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
    }()

从模态ViewController呈现UIImagePickerController
