ios - 如何向 UIAlert 添加功能

Question

所以我创建了两个函数（nenuProgressButton 和 nenuSurvivalButton） 我希望 nenuProgressButton 在单击时为进度条提供 0.1，并在选择 UIalert 上的动作标题时添加 0.5。我可以让大部分工作正常，但是当我选择“应用”（即 uialert 操作的标题）时，它会将 0.1 添加到我的进度条，然后如果我再次单击它，进度条几乎会冻结。或者如果我最初单击 uialert 动作标题它将添加 0.1，但是如果我单击 nenuProgress 按钮，它将添加 0.5 而不是 0.1，如果我再次单击进度按钮，进度条将减去 0.5，可以去回到之前的状态。我非常不确定是什么导致了这种并发症，但这是我的代码，非常感谢任何帮助，谢谢
