How to make a simple touch on iPhone ?

Hi guys,

I am struggling since a few days to make a simple touch on iPhone work like a gui.Button. I would like the touch to be from within a Rect, and the touch should launch a function.

So far i had that, wich never worked :

var Rect1 = Rect(95,24,83,130);

// first

if ( Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began){

if(Rect1.Contains(Vector2(Input.GetTouch(0).position.x,Input.GetTouch(0).position.y ))) {

 Comparer(1);    

} }

// second

var count = Input.touchCount;

for(var i : int = 0;i < count; i++){

var touch : Touch = Input.GetTouch(i);

if ( Rect1.Contains( touch.position ) ){

 Comparer(1);

}
}

// third

var count = Input.touchCount;

for (var i =0; i < Input.touchCount; ++i){

if (Input.GetTouch(i).phase == TouchPhase.Ended){

 if(Rect1.Contains(Vector2(Input.GetTouch(i).position.x,Input.GetTouch(i).position.y ))) {

   Comparer(1);
 }

}
}


I would like to understand why it dont work, and what i should do to have this simple GUI.Button like Touch, in a rect with just one touch.

thank you,
