Dragging multiple UIImageViews at the same time?

[JMKit]

Hi all,
So I'm looking for a way two drag two (or more) UIImageViews around at the same time, I guess that's what's being done in games like air hockey where u have 2 people playing, each with there own 'paddle'


So far to get my my images, in this example pic1 and pic2 to move around I'm using this code:

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
	
	UITouch *touch = [[event allTouches] anyObject];
	if ([touch view] == pic1) {
		CGPoint location = [touch locationInView:self.view];
		pic1.center = location;
	}
	if ([touch view] == pic2) {
		CGPoint location = [touch locationInView:self.view];
		pic2.center = location;
	}
}

But obviously this just lets you drag one or the other, and while i'm dragging one I can't move the other at the same time.

Any help here would be greatly appreciated, i know this question has been asked before but I couldn't find the answer yet, so hopefully someone can point out something obvious i'm overlooking XD

UITouch *touch = [[event allTouches] anyObject]; takes one touch - in my opinion you should iterate over the set of touches in stead of just picking one.
Try to use
for(UITouch *touch in [event allTouches])
instead.

I implemented multi-touch handling in my app Personal Photo Clock by accident ;-). I added scrollviews for the digits and added the handlers to the scroll views.
I found out that all views respont to the dragging at the same time.
If the for does not work try to add the handlers to the UIViews....

Thanks for the reply,

Did you mean literally replace:
UITouch *touch = [[event allTouches] anyObject];
with
UITouch *touch in [event allTouches]

or do you mean to add the line:
'for(UITouch *touch in [event allTouches])' as written somewhere else?

omg lol ok i figured it out.. so my code now looks like this:

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
	
	for(UITouch *touch in [event allTouches])
	if ([touch view] == pic1) {
		CGPoint location = [touch locationInView:self.view];
		pic1.center = location;
	}
	for(UITouch *touch in [event allTouches])
	if ([touch view] == pic2) {
		CGPoint location = [touch locationInView:self.view];
		pic2.center = location;
	}
}

and it works jus as i wanted
I'll have to buy your app soon to say thanks lol
