Only Seen View Animation Active in iCarousel

I have the following implementation.

However, I only want the displayed(active) view animation works, other view animation are disabled unless until user scrolls it. In my current solution, all view animation works at the same time, I need to find a way to stop other view animations.

- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSInteger)index reusingView:(UIView *)view{

    if (view == nil){
        if(index==0)
        {
            view=[[UIImageView alloc]initWithFrame:CGRectMake(30, 30, 600, 600)];
            ((UIImageView *)view).animationImages=[NSArray arrayWithObjects:[UIImage imageNamed:@"Walking-1.png"],
                                 [UIImage imageNamed:@"Walking-2.png"],
                                 [UIImage imageNamed:@"Walking-3.png"],
                                 [UIImage imageNamed:@"Walking-4.png"],
                                 [UIImage imageNamed:@"Walking-5.png"],nil];

            ((UIImageView *)view).animationDuration = 1.5;
            [((UIImageView *)view) startAnimating];
        }

        else if(index==1)
        {
            view=[[UIImageView alloc]initWithFrame:CGRectMake(30, 30, 600, 600)];
            ((UIImageView *)view).animationImages=[NSArray arrayWithObjects:[UIImage imageNamed:@"Biking-1.png"],
                              [UIImage imageNamed:@"Biking-2.png"],
                              [UIImage imageNamed:@"Biking-3.png"],
                              [UIImage imageNamed:@"Biking-4.png"],                                                   
                              [UIImage imageNamed:@"Biking-5.png"],nil];

            ((UIImageView *)view).animationDuration = 1.5;
            [((UIImageView *)view) startAnimating];
        }

        view.contentMode = UIViewContentModeCenter;
        [view.layer setMasksToBounds:YES];
    }
    return view;
}
