ios – Swift：由于未捕获的异常引起的应用程序终止’NSUnknownKeyException’

概述我正在开发一个简单的游戏,当加载一个特定的UIViewController(称为SPSwipes. swift)时,我遇到麻烦.在屏幕上,有三个按钮：5,10和25.当选择一个时,在该场景中设置一个变量,并且玩家移动到主游戏GameScene.swift. 据我所知,变量在GameScene中被识别,但是当我在模拟器中打开SPSwipes视图时,会出现’NSUnknownKeyException’ 我正在开发一个简单的游戏,当加载一个特定的UIVIEwController(称为SPSwipes. swift)时,我遇到麻烦.在屏幕上,有三个按钮：5,10和25.当选择一个时,在该场景中设置一个变量,并且玩家移动到主游戏GameScene.swift.

据我所知,变量在GameScene中被识别,但是当我在模拟器中打开SPSwipes视图时,会出现’NSUnkNownKeyException’错误.这是通过一个段落完成的.以下是错误更详细的信息：

正如你所看到的,我的第一个变量有五个问题(我会想像两个人之间会有错误).什么是’这个类不是关键的五重要的编码符合五重要的意义？我该如何解决？

我的SPSwipes.swift文件：

class SPSwipes: UIVIEwController {var no_of_swipes = 0@IBAction func fiveSwipes(sender: AnyObject) {    no_of_swipes = 5//and so on}

先谢谢你,

解决方法 问题是该按钮与许多IBActions相关联 – 其中三个不存在.我右键单击界面生成器中的按钮,并删除旧的和不相关的链接,解决问题. 总结
