Help with moving an object?

[isacart20]

I am looking just to do something simple.

I want to say have a square and when you touch an ipod screen the square moves up and when you release the square falls down.

Any help would be muchly appreciated.

I havent tried anything yet.

You can try to create UIImageView object add it to your view and animate it on touch events

UIImageView *im = [[UIImageView alloc] initWithFrame:CGRectMake(210, 250, 100, 100)];

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{
// here run animation
  		[UIView beginAnimations:nil context:nil];
		[UIView setAnimationCurve: UIViewAnimationCurveEaseIn];
		[UIView setAnimationDuration:5];
		
		[im setCenter:CGPointMake(im.center.x,im.center.y-400)];
		[UIView commitAnimations];
}


- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event 
{
// here run reverse animation - just a sample (you can manipulate variables)
}

or you can have square as a set of images and pass it to array?

NSArray *animationArray=[NSArray arrayWithObjects:
[UIImage imageNamed:@"SquareImage1.jpg"],
[UIImage imageNamed:@"SquareImage2.jpg"],
[UIImage imageNamed:@"SquareImage3.jpg"],
[UIImage imageNamed:@"SquareImage4.jpg"],
nil];

And then perform animation on it..

UIImageView *animationView=[[UIImageView alloc]initWithFrame:CGRectMake(0, 0,320, 460)];
animationView.backgroundColor=[UIColor redColor];
animationView.animationImages=animationArray;
animationView.animationDuration=3;

//you can always change this count if you want
animationView.animationRepeatCount=0;
[animationView startAnimating];
[self.view addSubview:animationView];
[animationView release];

Hope it helps..
Cheers
