}


#pragma mark - QuiltViewControllerDataSource

        }
        _images = [imageNames retain];
    }
    return _images;
}

- (UIImage *)imageAtIndexPath:(NSIndexPath *)indexPath {
    return [UIImage imageNamed:[self.images objectAtIndex:indexPath.row]];
}

- (NSInteger)quiltViewNumberOfCells:(TMQuiltView *)TMQuiltView {
    return [self.images count];
}

- (TMQuiltViewCell *)quiltView:(TMQuiltView *)quiltView cellAtIndexPath:(NSIndexPath *)indexPath {

    return cell;
}

#pragma mark - TMQuiltViewDelegate

- (NSInteger)quiltViewNumberOfColumns:(TMQuiltView *)quiltView {
    return 3;
}

- (CGFloat)quiltView:(TMQuiltView *)quiltView heightForCellAtIndexPath:(NSIndexPath *)indexPath {
