How to access camera flash on UIImagePickerController?

Question

I would like to know how to switch on the camera flash on the iPhone 4 with UIImagePickerController.

if ([UIImagePickerController isSourceTypeAvailable:UIImagePi         


        

Answer 1

-(void)flashSelected
{

if (PickerController.cameraFlashMode == 
UIImagePickerControllerCameraFlashModeOff) {

    if ([UIImagePickerController 
isFlashAvailableForCameraDevice:UIImagePickerControllerCameraDeviceRear ])

    {
        PickerController.cameraFlashMode = 
UIImagePickerControllerCameraFlashModeOn;
    }
 }
else
 {
    PickerController.cameraFlashMode = 
UIImagePickerControllerCameraFlashModeOff;
 }     
}

alternately..

-(void)_flashToggle
{
if (! [UIImagePickerController isFlashAvailableForCameraDevice:UIImagePickerControllerCameraDeviceRear ])
    return;

if (PickerController.cameraFlashMode == UIImagePickerControllerCameraFlashModeOff)
    PickerController.cameraFlashMode = UIImagePickerControllerCameraFlashModeOn;
else
    PickerController.cameraFlashMode = UIImagePickerControllerCameraFlashModeOff;  
}
