Pinch/pan libraries available?

[John Grden]

I've been looking around to see if there are any libraries available (c# preferably) for doing pinch/zoom/pan gestures on iPad/iPhone

Does anyone know of any they can pass along?

I just hadn't used the word "pinch" until now:

here's my condensed version:

if ( iPhoneInput.touchCount == 2 )
{
	iPhoneTouch touch1 = iPhoneInput.GetTouch( 0 );
	iPhoneTouch touch2 = iPhoneInput.GetTouch( 1 );
	
	// Find out how the touches have moved relative to eachother:
	Vector2 curDist = touch1.position - touch2.position;

	Vector2 prevDist = (touch1.position - touch1.positionDelta) - (touch2.position - touch2.positionDelta);
	
	float touchDelta = curDist.magnitude - prevDist.magnitude;

        // move camera in world coordinates

	//Camera.main.transform.position -= new Vector3(0, 0, touchDelta * .5f);

        // translate along local coordinate space
	Camera.main.transform.Translate(0,0,touchDelta*.5f);	
}
