【问题描述】：

当我的用户注册时，他们使用个人资料图片和直接保存到 firebase 数据库中的用户名。用户注册后，（个人资料图片和用户名）等用户信息不会出现在更新的用户个人资料屏幕上，我该如何更新用户个人资料

 Auth.auth().addStateDidChangeListener  auth, user in
        if Auth.auth().currentUser != nil 
             guard  let uid = Auth.auth().currentUser?.uid else 
                 return 
        Database.database().reference().child("users").child(uid).observeSingleEvent(of: .value, with:  (snapshot) in
            guard let dict = snapshot.value as? [String: Any] else  return
        let user = Auth.auth().currentUser
        if let user = user 
          let uid = user.displayName
            let Profilephoto = self.ProfileImage

          
            self.DisplayName.text = user?.displayName
            func getData(from url: URL, completion: @escaping (Data?, URLResponse?, Error?) -> ()) 
               URLSession.shared.dataTask(with: url, completionHandler: completion).resume()
            
            func downloadImage(from url: URL) 
               getData(from: url) 
                  data, response, error in
                  guard let data = data, error == nil else 
                     return
                  
                  DispatchQueue.main.async() 
                    self.ProfileImage.image = UIImage(data: data)

   let DisplayName = user?.displayName
let changeRequest = Auth.auth().currentUser?.createProfileChangeRequest()
changeRequest?.displayName = DisplayName
changeRequest?.commitChanges  (error) in

【问题讨论】：

您的个人资料图片是保存在 Firebase 数据库还是 Firebase 存储中？

【参考方案1】：

好像self.ProfileImage 有点像UIImageView。

试试self.ProfileImage.image = UIImage(data: data)
