ios - Swift - 从模态视图访问 UIImagePickerController

Question

有没有办法从模态视图中呈现 UIImagePickerController？

在我的例子中，我有一个名为 MakeWishView 的 class，它是一个 UIView，如果用户点击，他应该能够选择一个图像在 MakeWishView 内的一个 button 上。我现在的问题是我无法调用 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 添加委托(delegate)

 class MakeWishView:UIView {
    weak var delegate:VCName?

或

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