iOS UIView CABasicAnimation Problem

[lamfan]

Here is my code, if I add the CABasicAnimation,

the UITouch *touch = [[event allTouches] anyObject]; will return to MainView not UIImageView,

is there other way to add the CABasicAnimation?

MainView.m

- (void)createGame:(int)numberDot
{
	for(int i = 0; i <numberDot; i++) {
		float xPos = 0;
		float yPos = 60 * i;
		imageView = [[UIImageView alloc] initWithFrame:CGRectMake(xPos, yPos, 57.0, 57.0)];
		imageView.image =[UIImage imageNamed:@"Icon8.png"];
		imageView.userInteractionEnabled = YES;
		[self addSubview:imageView];
		[imageViewArray insertObject:imageView atIndex:i]; 
		
		CABasicAnimation *theAnimation;
		theAnimation = [CABasicAnimation animationWithKeyPath:@"position.x"];
		theAnimation.duration = 20.0;
		theAnimation.repeatCount = 2;
		theAnimation.autoreverses = YES;
		theAnimation.fromValue = [NSNumber numberWithFloat:10.0];
		theAnimation.toValue = [NSNumber numberWithFloat:300.0];
		[[imageView layer] addAnimation:theAnimation forKey:@"animateOpacity"];

		[imageView release];
	}
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{	
	UITouch *touch = [[event allTouches] anyObject];
	for(int i = 0; i < [imageViewArray count]; i++) 
	{
		id anObject = [[imageViewArray objectAtIndex:i] retain];

		if([touch view] == anObject)
		{
			[anObject removeFromSuperview];
			[imageViewArray removeObjectAtIndex:i];
		}
	}
}
