Scaling at runtime

I have a couple of small canvases holding some icon images in them which look fine on iPhone.

How do I scale the canvas to look appropriate on iPad?

If you want to change the height or width or any of the auto-layout constraints on your canvases, use iOSLayoutConstraint to create a reference to the constraint(s) you want to change and then change the property you want, eg the offset.

Thanks Jason, I thought that was above my pay grade but it strangely makes sense. Cheers Martin
