我在我的游戏中添加了一个老式的高分输入屏幕，用户点击每个字母来输入他们的名字。
每个字母、符号或短语（“DEL”、“SP”等）都是一个SKLabelNode而且点击“,”和“.”非常困难。不过字符和一些符号。每次点击都会通过通常的方式检测到touchesBegan
为了让拘留更容易，我计划在每个字母后面放置一个更大的节点并更新touchesBegan检测标签本身或其他标签上的触摸，在这种情况下，只需使用触摸的子节点（这将是字母或短语）。
在我这样做之前，我想知道是否有一种简单的方法来实现我想要的，可以通过检测最近的SKLabelNode触摸等
只是基于 @KnightOfDragon 所说的，我将为每个键创建 SKSpriteNode 的子类。这样它可以使您的代码客观化且美观！
这里还有很多事情可以做，但我很快就完成了。它没有所有字母，也不知道如何处理 del、空格、return，但我认为你的代码已经知道如何处理这些字母。
Key 类使用协议来发送按下的键，因此您不必担心捕获场景中的每个关键区域
所以我输入了其余的键并添加了一些空格填充选项。我的字体和你的不一样，但是看起来很酷
