UIView {
    name = Index;
    edges = 0;
    bgColor = #eeeeee;
    interfaceOrientation = p;
    
    UIView {
        id = headView;
        top.left.right = 0;
        x-height = 88;
        height = 64;
        
        UIView {
            id = navView;
            left.right.bottom = 0;
            height = 44;
            
            UILabel {
                center = parent;
                text = "首页";
                font = 20;
            }
            
            UIButton {

                left = 10;
                width = 60;
                height = 44;
                centerY = parent;
                text = "左按钮";
                textColor = #2a2a2a;
            }
            
            UIButton {
                id = headerRightButton;
                right = -10;
                width = 60;
                height = 44;
                centerY = parent;
                text = "右按钮";
                textColor = #a2a2a;

        }
        
        UIView {
            left.right.bottom = 0;
            height = 1;
            bgColor = #3d3d3d;
        }
    }
    
    UIView {
        id = contentView;
        bottom.left.right = 0;
        top = headView.bottom;
        
        UICollectionView {
            id = collectionView;
            edges = 0;
            
            section {
                headerClass = BBBB;
                headerSize = parent,150;
                name = "广告";
            }
            section {
                headerClass = BBBB;
                headerSize = parent,100;
                name = "产品分类";
            }
            section {
                headerClass = BBBB;
                headerSize = parent,44;
                name = "产品推荐";
                cellClas = AAA6;
                cellSize = (parent-5-5-5)/2,.width;
                cellCount = 16;
                edgeInsets = 5,5,5,5;
                lineSpacing = 5;
                interitemSpacing = 5;
            }
        }
    }
}

效果：

interfaceOrientation 是用来设置选择方向的。其值包括all,landscape,portrait,left,right,portraitUpsideDown,allButUpsideDown。

UICollectionView 中使用 section 可以指定 对应的header，footer，cell。
