Firebase创建用户Swift不起作用

Question

下面我刚刚键入的错误显示“无法将类型'（ ， ）-> Void的值覆盖到预期参数类型'（NSERROR！）-> Void！）”

在这行代码上：怎么了？

FIREBASE_REF.createUser(email, password: password, withCompletionBlock: {(error,authData) -> Void in

@IBAction func creatAccountAction(sender: AnyObject) {
        let email = self.emailTextField.text
        let password = self.passwordTextField.text

        if email != "" && password != ""
        {
            FIREBASE_REF.createUser(email, password: password, withCompletionBlock: {(error,authData) -> Void in

            if error != nil {

                FIREBASE_REF.authUser(email, password: password, withCompletionBlock: { (error, authData) -> Void in

                    if error == nil {

                        NSUserDefaults.standardUserDefaults().setValue(authData.uid, forKey: "uid")
                    }
                    else {
                        print (error)
                    }
                })
            }
            else {
                print (error)
            }

            }

            )}

        else

Answer 1

尝试这个：

FIREBASE_REF.createUser(email, password: password, withCompletionBlock: {(error) -> Void in

该块可能只有一个参数

Answer 2

创建用户有两种选择，一种是创建用户，如果失败则返回错误（withCompletionBlock），另一种还返回authData（withValueCompletionBlock）：这就是您想要的。

myRootRef.createUser(email, password: pw, withValueCompletionBlock: { error, result in

            if error != nil {
                print("error creating user")
            } else {
                let uid = result["uid"] as! String
                NSUserDefaults.standardUserDefaults().setValue(uid, forKey: "uid")
                //pass the parameters to another function to auth the user
                self.authUserWithAuthData( email, password: pw ) 
            }

        })
