In other language we use the following.

CGPoint a, b;
if(a == b)
But in the objective c manner it is like this.

CGPoint location;
CGPoint lastPoint; 

if (CGPointEqualToPoint(location, lastPoint)) {


pretty straight forward.

Have a good day.

 Getting location for touch!
Get the position!

-(void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{

    UITouch *touch = [touches anyObject];

    CGPoint location = [touch locationInView:touch.view];
