如何以编程方式确定我的应用程序是在iPhone，iPad还是iPhone 4上运行？
我刚刚使用cocos2d完成了我的iPhone游戏。但是在我把它放在AppStore之前，我想让它在iPad（有更大的屏幕）和iPhone 4（有更大的分辨率）上工作。
那么，我该如何确定以编程方式我的应用程序在iPhone，iPad或iPhone 4上运行，以便能够在我的游戏中使用正确的坐标/图像？
I just finish my iPhone game using cocos2d. But before I put it on the AppStore, I'd like to make it work on iPad (which have a bigger screen) and iPhone 4 (which have a bigger resolution).
So, how can I determine programmatically that my app is running on an iPhone, iPad or iPhone 4, to be able to use the correct coordinates / images in my game?
感谢您的帮助！
iPhone和iPhone 4之间 - 报告的尺寸为仍然 320× 480，因此您无需更改任何有关坐标的信息。如果您需要高分辨率UI图像，请为图像创建 @ 2x 备选方案。
Between iPhone and iPhone 4 — The size reported is still 320×480, so you don't need to change anything about the coordinates. Create an @2x alternative for the images if you need a high resolution UI image.
