Swift - 从模态视图访问 UIImagePickerController

Question

有没有办法从模态视图中present 和UIImagePickerController？

在我的例子中，我有一个名为MakeWishView 的class，它是一个UIView，如果用户在MakeWishView 中点击button，他应该能够选择图像。我现在的问题是我不能打电话给present，因为MakeWishView 不是ViewController，而是UIView。

我想这样称呼：

@objc private func wishImageButtonTapped(){
    showImagePickerController()
    print("wishImageButtonTapped")
}

// image picker
extension MakeWishView: UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    @objc func showImagePickerController(){
        let imagePickerController = UIImagePickerController()
        imagePickerController.delegate = self
        present(imagePickerController, animated: true, completion: nil) // -> error
    }
}

Answer 1

向呈现的 vc 添加一个委托

 class MakeWishView:UIView {
    weak var delegate:VCName?

或

 let root = (UIApplication.shared.delegate as! AppDelegate).window!.rootViewController
 root.present(imagePickerController, animated: true, completion: nil)
