Question

我正在使用登录创建一个简单的应用程序，使用firebase注册尝试实现图像上传功能，但会出现以下错误。因为我是新手，所以非常感谢帮助。

import Foundation
import Firebase
import FirebaseAuth
import FirebaseStorage
import FirebaseDatabase
let roofRef = FIRDatabase.database().reference()
class DataService {

static let dataService = DataService()

private var _BASE_REF = roofRef

  private var _users_REF = roofRef.child("users")
var BASE_REF: FIRDatabaseReference{

return _BASE_REF

}


var storageRef: FIRStorageReference {

return FIRStorage.storage().reference()

}


var fileUrl: String!



func SignUp(username: String, email: String, Password: String, data: NSData)
{
FIRAuth.auth()?.createUser(withEmail: email, password: Password, completion: { (user, error) in

    if let error = error{

        print(error.localizedDescription)
    }


    let changeRequest = user?.profileChangeRequest()
    changeRequest?.displayName = username
    changeRequest?.commitChanges(completion: { (error) in

        if let error = error {
        print(error.localizedDescription)

            return
        }

    })

    let filePath = "profileImage/\(user!.uid)"
    let metadata = FIRStorageMetadata()
    metadata.contentType = "image/jpeg"

    self.storageRef.child(filePath).putData(data, metadata: metadata, completion: { (metadata, error) in

        if let error = error {

            print("\(error.description)")
            return
        }

        self.fileURL = metadata?.downloadURLs![0].absoluteString
        let changeRequestPhoto = user!.profileChangeRequest()
        changeRequestPhoto.photoURL = NSURL(string: self.fileURL)
        changeRequestPhoto.commitChangesWithCompletion({ (error) in
            if let error = error {
                print(error.localizedDescription)
                return
            } else {

                print("profile update")
            }

            })
        let appDelegate: AppDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
        appDelegate.login()

    })
})

}

}

尝试使用此代码＆gt;＆gt;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
  <div class="content">

  </div>
  <div class="menu">
    <span class="current" style="">United States</span>
    <ul class="list">
      <li class="option">United Arab Emirates</li>
      <li class="option">United States</li>
    </ul>
  </div>
</div>

＆＃39; NSData的＆＃39;不能隐含地转换为＆＃39;数据＆＃39 ;;你的意思是使用＆＃39;作为＆＃39;明确转换？
