在 iOS Swift 中解析密码重置错误

Question

我正在使用下面的代码重置密码，如解析文档中所述：https://parse.com/docs/ios/guide#users-resetting-passwords 但是我收到错误： "cannot invoke "requestPasswordResetForEmailInBackground" 参数类型为 (string (bool!,nserror!)->Void)

我使用的代码是：

  var emailVar = emailField.text
    PFUser.requestPasswordResetForEmailInBackground(emailVar) { (success: Bool, error: NSError!) -> Void in

        if (error == nil) {

            let alertView = UIAlertController(title: "Password recovery e-mail sent", message: "Please check your e-mail inbox for recovery", preferredStyle: .Alert)
            alertView.addAction(UIAlertAction(title: "Ok", style: .Default, handler: nil))
            self.presentViewController(alertView, animated: true, completion: nil)

        }else {

            let alertView = UIAlertController(title: "Could not found your e-mail", message: "There is no such e-mail in our database", preferredStyle: .Alert)
            alertView.addAction(UIAlertAction(title: "Ok", style: .Default, handler: nil))
            self.presentViewController(alertView, animated: true, completion: nil)

        }
    }

在新的解析中 api 错误更改为 optional 值，使用方式如下：

PFUser.requestPasswordResetForEmailInBackground(emailVar) {
        (success: Bool, error: NSError?) -> Void in

}
