使用Firebase更新配置文件图像

Question

因此，我目前正在尝试在用户创建个人资料后更新我的用户个人资料图片。这是代码。

它将选择的图像保存到存储中，但是我的数据库保持不变。 profileimageurl完全不变。

如何设置它才能起作用？

我想念什么？

在collectionView单元格中保存我的个人资料图像也有什么关系吗？

func didtapImage() {
print("from userprofile controller")


let imagePickerController = UIImagePickerController()
imagePickerController.delegate = self
imagePickerController.allowsEditing = true
present(imagePickerController, animated: true) {

}


   }

      func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
print("123")

if let editedImage = info["UIImagePickerControllerEditedImage"] as? UIImage {
    print("what's going on here")

    let image = editedImage
     guard let uploadData = UIImageJPEGRepresentation(image, 0.3) else {return}
    let filename = NSUUID().uuidString
    let storageItem = Storage.storage().reference().child("profile_Image").child(filename)

    storageItem.putData(uploadData, metadata: nil) { (metadata, err) in
        if let err = err {
            print("failed to upload", err)
            return
        }
        storageItem.downloadURL(completion: { (downloadURL, err) in
            guard let profileImageUrl = downloadURL?.absoluteString else {return}
            print("successfully uploaded profile image:", profileImageUrl)
            guard let currentUser = Auth.auth().currentUser?.createProfileChangeRequest() else {return}

            let dictionaryValues = ["profileImageUrl": profileImageUrl]
            let values = [currentUser: dictionaryValues]

            currentUser.photoURL = URL(fileURLWithPath: profileImageUrl)
            currentUser.commitChanges(completion: { (err) in
                if let err = err {
                    print("not updated error", err)
                    guard let uid = Auth.auth().currentUser?.uid else {return}
                    let ref = Database.database().reference().child("users").child(uid)
                    ref.setValue(values, withCompletionBlock: { (err, ref) in
                        print("changedImage")
                        if let err = err {
                            print("did not get image",err)
                        }
                        print("updated user's profile image")
                    })
                }
                print("updated user image", profileImageUrl)
                self.collectionView?.reloadData()
            })
        })
    }




} else if let originalImage = info["UIImagePickerControllerOriginalImage"] as? UIImage {

    let image = originalImage
   //same thing as above.
  }
