我正在开发一款通用益智游戏，其中我为 iphone4 和 iphone3 使用了单独的图像，iphone4 图像的大小是 iphone3 图像的两倍。我的问题是 iphone4，iphone4 图像的触摸区域是双倍尺寸，假设我的 iphone4 图像尺寸是 20*40，iphone3 是 10*20，问题是 iphone4 图像的触摸区域是 40*80 i不知道它是如何发生的，我在我的代码中解决了这个问题，但我没有得到这个问题的任何解决方案，在 iphone3 中触摸工作正常，在精灵矩形中使用。
你能帮我解决这个问题还是告诉我我忘记为iphone4触摸编码什么，以便它在精灵（图像）矩形中触摸
预先感谢。这是我的代码：
