Setting the anchorPoint to {0.0, 0.0} works as well (as Liam already pointed out).

Here's the full code snippet for changing the anchorPoint without changing the layer's position on screen:

     layer.anchorPoint = CGPointMake( 0.0, 0.0 );

     CGPoint position = layer.position;
     CGSize size = layer.bounds.size;

     CGFloat posX = position.x - size.width / 2.0;
     CGFloat posY = position.y - size.height / 2.0;

     layer.position = CGPointMake( posX, posY );
