Zooming on an Animation using UIScrollView

Question

Hi Guys, I've got a UIScrollView filled with images, one of the images is animated (i.e. has 45 frames repeating within it as 45 separate images). However, you can zoom in on the images using pinch gestures, but on the animation you cannot. Is there a way to fix this?

Here's some of my code to help:

- (void)setUpView {
    //INITIALISE PAGING SCROLL VIEW
    CGRect pagingScrollViewFrame = [[UIScreen mainScreen] bounds];
    pagingScrollViewFrame.origin.x = 0;
    pagingScrollView = [[UIScrollView alloc] initWithFrame:pagingScrollViewFrame];
    pagingScrollView.contentMode =  UIViewContentModeScaleAspectFit;

    //CONFIGURE PAGING SCROLL VIEW  
    pagingScrollView.pagingEnabled = YES;
    pagingScrollView.backgroundColor = [UIColor clearColor];
    pagingScrollView.contentSize = CGSizeMake(pagingScrollViewFrame.size.width*7, pagingScrollViewFrame.size.height);

    //ACTIVATE PAGING SCROLL VIEW
    self.view = pagingScrollView;

    //ADD PAGES TO SCROLL VIEW
    for (int i = 0; i < 7; i++){
        ImageScrollView *page = [[[ImageScrollView alloc] init] autorelease];
        [self configurePage:page forIndex:i];
        [pagingScrollView addSubview:page];
        [pageArray addObject:page];
    }

- (void)configurePage:(ImageScrollView *)page forIndex:(NSUInteger)index
{
    page.index = index;
    page.frame = [self frameForPageAtIndex:index];
    if (index == 4){
        [self addAnimation:page];
    }else {
        [page displayImage:[self imageAtIndex:index]];
    }
}
