NSUserDefaults - 保存和检索“高分”(NSUserDefaults - Saving and retrieving “High Scores”)

 我只是学习编程和做一些SWIFT教程。 我做了尽可能多的研究，但似乎缺少一些关键方面。 我有一个简单的游戏，当玩家死亡时，我想检查他们的分数与之前保存的高点。 如果它更高，则保存新分数。 
 
 在标题屏幕上显示最高分数。 
 
 这是我正在使用的当前代码; 
 
NSUserDefaults.standardUserDefaults().integerForKey("highscore")

    if score > NSUserDefaults.standardUserDefaults().integerForKey("highscore") {
        NSUserDefaults.standardUserDefaults().setInteger(score, forKey: "highscore")
        NSUserDefaults.standardUserDefaults().synchronize()
    }

    NSUserDefaults.standardUserDefaults().integerForKey("highscore")
 
 我无法解决的问题只是如何打印高分！ 我试过用; 
 
hiScoreText.text = "Hi Score :  \(highscore)"
 
 但正如我猜测那不正确。 我使用什么变量或如何“读取”已保存的高分？ 
 
 对于一个新人的任何建议将不胜感激。 

I am just learning to program and doing some SWIFT tutorials. I have done as much research as I could but seem to be missing some critical aspect. I have a simple game and when a player dies I want to check their score against the previously saved high. If it's higher it's to save the new score.
 
On a title screen the highest score is displayed.
 
Here is the current code I am using;
 
NSUserDefaults.standardUserDefaults().integerForKey("highscore")

    if score > NSUserDefaults.standardUserDefaults().integerForKey("highscore") {
        NSUserDefaults.standardUserDefaults().setInteger(score, forKey: "highscore")
        NSUserDefaults.standardUserDefaults().synchronize()
    }

    NSUserDefaults.standardUserDefaults().integerForKey("highscore")
 
The problem I cannot solve is simply how to print the highscore! I tried using;
 
hiScoreText.text = "Hi Score :  \(highscore)"
 
but as I guessed that isn't correct. What variable do I use or how do I "read" the highscore that has been saved?
 
Any advice for a new guy would be greatly appreciated.
