Front facing camera in UIImagePickerController

Question

I am developing the front facing camera app in iPad2 by using the UIImagePickerController.

When I capture the image it\'s shows as flipped from left to

Just to add how I have just achieved this without subclassing UIImagePickerController and without adding extra buttons to the camera view.

Simply listen for this notification which is fired several times whenever the camera is changed:

[[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(cameraChanged:)
                                                 name:@"AVCaptureDeviceDidStartRunningNotification"
                                               object:nil];

Then use this method to flip the camera view:

- (void)cameraChanged:(NSNotification *)notification
{
    if(imagePicker.cameraDevice == UIImagePickerControllerCameraDeviceFront)
    {
        imagePicker.cameraViewTransform = CGAffineTransformIdentity;
        imagePicker.cameraViewTransform = CGAffineTransformScale(imagePicker.cameraViewTransform, -1,     1);
    } else {
        imagePicker.cameraViewTransform = CGAffineTransformIdentity;
    }
}
