IPhone - Using UIView Animation in a Trojan Place

Hey guys, I'm just confused here now, I want to present the UIView animation on the finger press by creating the UIView where the finger is. Is it possible?

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    UITouch * touch = [touches anyObject];
    CGPoint pos = [touch locationInView: [UIApplication sharedApplication].keyWindow];
    NSLog(@"Position of touch: %.3f, %.3f", pos.x, pos.y);
    //CGRect touchFrame = CGRectMake(pos.x, pos.y, 100, 100);
    UIView *box = [[UIView alloc] initWithFrame:CGRectMake(pos.x, pos.y, 100, 100)];
    NSLog(@"%f", box.frame.origin.x);
    [self.view addSubview:box];
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:1.0];
    [UIView setAnimationTransition:110 forView:box cache:NO];
    [UIView commitAnimations];
    [box removeFromSuperview];
    [box release];
}

Any suggestions are more than welcome.

Due to u written by the next line

[box removeFromSuperview];
    [box release];

This line u should be called after the animation of the image in the box is completed.

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

    UITouch * touch = [touches anyObject];

    CGPoint pos = [touch locationInView: [UIApplication sharedApplication].keyWindow];

    UIView *box = [[UIView alloc] initWithFrame:CGRectMake(pos.x, pos.y, 100, 100)];

    [self.view addSubview:box];

    [UIView beginAnimations:nil context:nil];

    [UIView setAnimationDuration:1.0];

    [UIView setAnimationTransition:110 forView:box cache:NO];

    [UIView commitAnimations];

[self performSelector:@selector(releaseBoxImge:) withObject:box afterDelay:1.0];

}


-(void)releaseBoxImge:(UIView *)boxImage
{

[boxImage removeFromSuperview];

    [boxImage release];

}

As RRB said, do it removeFromSuperViewafter the animation is complete (I'm not sure what its code will be). It should look like this, I think:

//initializations of everything here ..
[UIView animateWithDuration:1.0                  
 animations:^
 {
   //do animations here
 }
 completion:^(BOOL finished)
 {
    //do clean up here
 }];
