Swift + 解析注销错误

Question

我在按下注销按钮时尝试终止用户会话时出错。有人知道我哪里出错了吗？提前致谢这是代码

@IBAction func logoutButtonTapped(sender: AnyObject) {

    NSUserDefaults.standardUserDefaults().setBool(false, forKey: "isUserLoggedIn");
    NSUserDefaults.standardUserDefaults().synchronize();

    PFUser.logOutInBackgroundWithBlock({ (error:NSError!) -> Void in
        self.performSegueWithIdentifier("loginView", sender: self);

    })

错误：'无法使用类型为'((NSError) -> Void)'的参数列表调用'logOutInBackgroundWithBlock'

Answer 1

从参数中删除类型说明符 NSError!。

PFUser.logOutInBackgroundWithBlock({(error) -> Void in
  self.performSegueWithIdentifier("loginView", sender: self);
})
