是否可以支持iPad1但不支持iPhone3GS？

Question

I have been looking at removing support for iPhone3GS for a title I am developing. I realise I can use the device capabilities to stop people using certain devices but I cant find a specific setting which would stop the support for only the 3GS?

Thanks

Answer 1

You can detect for a forward facing camera, which was introduced in the iPhone 4, with

if( [UIImagePickerController isCameraDeviceAvailable: 
         UIImagePickerControllerCameraDeviceFront ])
{
   // do something
} else {
   // you have an iPhone 3GS or less
}

I'm assuming you are not supporting models less than 4. If not, and you only want to eliminate the 3GS specifically, but allow the iPhone 3G, you can check for video capability. 3GS has it, 3 and less don't.
