How to find out if the device supports autofocus

Question

I would like to know if there is a way to check if the device’s camera supports autofocus?

The only solution I found was to check the device name to see if it supports autofocus or not. But I did not like it, because it did not work for the future device.

Using the new AVFoundation APIs in iOS 4.0, you can verify this by requesting an instance of AVCaptureDevice for the camera using your -isFocusModeSupported: method. Focus modes include AVCaptureFocusModeLocked , AVCaptureFocusModeAutoFocus and AVCaptureFocusModeContinuousAutoFocus .
