ios - 带有overlayskscene Xcode Swift 的屏幕触摸Scenekit 导致应用程序崩溃

Question

嘿，好吧，在 Overlayskce 的场景套件 3D 游戏中识别 HUD 触摸的最佳方法是什么。因为我有一个名为“AButton”的按钮，但是当我触摸按钮或屏幕时，游戏会在几个小时的搜索后崩溃，我猜问题是场景套件上的 touchbegin 不太配合。但是我该如何做到这一点，以便当用户触摸 HUD 上的按钮时，它不会使系统崩溃并且它实际上可以工作。你能看看我的代码并重写它吗？我是使用触摸开始还是使用 HitTest 或其他东西(我以前从未使用过 HitTest )？

您的手势识别器配置为在用户点击 View 时调用 handleTap: 方法，但您没有定义该方法。

func handleTap(gestureRecognizer: UITapGestureRecognizer) {
    // do something
}

如果您想直接使用touchesBegan，则不需要手势识别器。
