请注意，我是IOS开发的新手，尤其是Swift。我已经在连接到常规“配置文件”视图控制器的视图控制器中创建了“编辑配置文件页面”。在此编辑个人资料视图控制器上，用户可以更改其个人资料图片和封面照片。我很难理解如何在用户选择图像并单击“保存按钮”后，如何允许用户将其照片上传到firebase，一旦他们单击“保存”按钮，我希望它上传图像，然后将其重定向到常规个人资料视图。我已阅读其他文章并观看了其他教程，但无法获得成功上传两个图像的结果。到目前为止，这是我的代码，没有任何将图像上传到Firebase的调用。

import UIKit
import Foundation
import Firebase
import FirebaseDatabase

class NewEditProfileViewController: UIViewController,UIImagePickerControllerDelegate,UINavigationControllerDelegate {

    @IBOutlet weak var imageView1: UIImageView!
    @IBOutlet weak var imageView2: UIImageView!

    var imagePicker = UIImagePickerController()
    var imagePicked = 0

    var selectedImage1: UIImage?

    override func viewDidLoad() {
        super.viewDidLoad()



        imagePicker.delegate = self
        imagePicker.sourceType = .photolibrary
        imagePicker.allowsEditing = true
    }


    @IBaction func chooseImage1(_ sender: Any) {
        if UIImagePickerController.isSourceTypeAvailable(UIImagePickerController.SourceType.photolibrary){
            imagePicked = (sender as AnyObject).tag
            present(imagePicker,animated: true)
        }

        }

    @IBaction func chooseImage2(_ sender: Any) {
        if UIImagePickerController.isSourceTypeAvailable(UIImagePickerController.SourceType.photolibrary){
            imagePicked = (sender as AnyObject).tag
                present(imagePicker,animated: true)
    }

    }

    func imagePickerController(_ picker: UIImagePickerController,didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        let pickedImage = info[UIImagePickerController.InfoKey.editedImage] as? UIImage

        if imagePicked == 1 {
            imageView1.image = pickedImage
        } else if imagePicked == 2 {
            imageView2.image = pickedImage
        }
        dismiss(animated: true)
    }

    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        dismiss(animated: true)
    }

@IBaction func saveButton(_ sender: Any) {
    }


    @IBaction func backButton(_ sender: Any) {
         self.dismiss(animated: true,completion: nil)
        }
    }

谢谢您的帮助！就像我说的那样，Swift和Firebase总体上对我来说是一个新概念。
