我正在开发一款通用益智游戏，其中我使用了iphone4和iphone3的单独图像，iphone4图像的尺寸是iphone3图像的两倍。我的问题是iphone4，iphone4图像的触摸区域图像是双倍尺寸，假设iphone4的图像尺寸是20 * 40而iphone3的图像尺寸是10 * 20，问题是iphone4图像的触摸区域是40 * 80 i不知道我的代码是如何发生的，但是我没有得到任何解决这个问题的方法，触摸在iphone3中运行正常，采用精灵矩形。
你能帮助我解决这个问题，或者告诉我忘记为iphone4触摸编码，以便在sprite（图像）矩形中触摸
提前感谢。 这是我的代码：

在您的app delegate
中执行此操作[director enableRetinaDisplay:YES];
并确保您的图片符合惯例。
例如
对于iPhone3，假设您的图像为image.png，那么您的视网膜图像必须为image-hd.png
答案 1 :(得分：0)
嗯，一切都应该在点上，例如我不认为你需要围绕UIScreen scale属性的逻辑，你的scale = 1的逻辑应该在视网膜和非视网膜显示器上相同。
快速尝试：更改比例＆gt; 1.0比例＆gt; 3.0（if应该总是分支到else部分，你在iPhone 3上声明'工作'），只是为了看看这是否正确。如果是，删除完全围绕规模的逻辑并清理:) ...在我的代码中，我没有一个合理的案例来确定比例是否为1.0或其他。
