推荐答案

由于iPhone 3G，3G，4、4S的屏幕尺寸相同；您将无法找出其中哪一个是视网膜显示(AFAIK).但是，从iPhone4起，该设备具有前置摄像头，因此，您可以使用它.您可以让您的应用程序需要前置摄像头(仅作为示例；还有其他硬件，这是iPhone4新引入的).

As the screen size is same for iPhone 3G, 3Gs, 4, 4S; You won't be able to find out which one is retina display among them (AFAIK). But, from iPhone4 the device is having front facing camera, so, You can use that. You can have your App require front-facing camera (Just an example; there are other hardwares too, newly introduced from iPhone4) device capability.

这些是使用 UIRequiredDeviceCapabilities 键在应用程序的plist文件中指定的.

These are specified in the plist file for the app using the UIRequiredDeviceCapabilities key.

前置摄像头，它将仅限于具有消除3G和3GS(非视网膜显示器)的设备.

A front-facing camera, that would limit it to those devices that have that, eliminating the 3G and 3GS (They are Non-retina displays).
