Open image from JSQMessagesViewController

I'm using JSQMesssagesViewController to build a messaging app. I can now send an image using this, but would like to tap the image to open in full screen. This functionality would be similar to the standard messaging application that allows you to tap on an image "bubble", and pinch to zoom in and out. Has anyone had experience doing this with JSQMessagesViewController? Thanks to those who who can lend assistance!

JSQmessage does not handle that but you can add this functionality in this method and by using zoomPopup class:

- (void)collectionView:(JSQMessagesCollectionView *)collectionView didTapMessageBubbleAtIndexPath:(NSIndexPath *)indexPath
{
    JSQMessage *message = [self.messageModelData.messages objectAtIndex:indexPath.row];

    if (message.isMediaMessage) {
        id<JSQMessageMediaData> mediaItem = message.media;

        if ([mediaItem isKindOfClass:[JSQPhotoMediaItem class]]) {

            NSLog(@"Tapped photo message bubble!");

            JSQPhotoMediaItem *photoItem = (JSQPhotoMediaItem *)mediaItem;
            [self popupImage:photoItem.image];
        }
    }
}

- (void) popupImage: (UIImage*)image
{
    UIWindow *window = [[UIApplication sharedApplication] keyWindow];
    UIView *topView = window.rootViewController.view;
    imageView = [[UIImageView alloc] initWithImage:image];

    zoomPopup  *popup = [[zoomPopup alloc] initWithMainview:topView andStartRect:CGRectMake(topView.frame.size.width/2, topView.frame.size.height/2, 0, 0)];
    [popup showPopup:imageView];
}
