【问题描述】：

基本上我的应用程序运行良好，但是当我尝试在 Xcode 中的 XS 模拟器以外的任何其他模拟器上运行它时，主菜单按钮不再起作用，而且我没有去哪里寻找错误，因为什么也没有正在抛出任何错误。此外，当我将打印语句放在节点内时，打印语句会打印到控制台，告诉我屏幕正在检测选择，但由于某种原因，代码无法运行。这很奇怪，因为它是被调用函数中的一个简单 if else 语句，所以我看不出它不应该运行的原因。

【问题讨论】：

顺便说一句，在“普通”ios 中简单地执行按钮/等操作非常常见，并且仅使用 SKScene 显示游戏本身。

等待 - 一般来说 spriteKit/Metal 等在模拟器中不起作用！你必须建立一个电话！它可能只是在新的 XS 模拟器中“巧合”地工作。就是这样。仅适用于手机。

我没有使用任何自动布局约束。此外，我知道这些按钮正在被选中，因为当我触摸它们时我正在打印到控制台，并且可以看到它正在检测选择。

对@Alec，答案在下面！很简单...

有趣。所以我可以放心，它适用于任何 iPhone 型号？对不起，如果我听起来很密集。

你必须构建到手机！
