公司給的UI圖要求如下

這個(gè)用collection還是比較好做的
效果如下

在xib里直接有footer和header的屬性,如果用代碼的話,貼一組代碼記錄一下
新建一個(gè)控制器繼承UICollectionViewController

{
    // 創(chuàng)建瀑布流對(duì)象,設(shè)置cell的尺寸和位置
    UICollectionViewFlowLayout *layout = [[UICollectionViewFlowLayout alloc] init];
    // 設(shè)置滾動(dòng)的方向
    layout.scrollDirection = UICollectionViewScrollDirectionVertical;

    CGSize size = [UIScreen mainScreen].bounds.size;
    layout.itemSize = size;
    // 設(shè)置cell之間的間距
    layout.minimumInteritemSpacing = 10;
    // 設(shè)置行距
    layout.minimumLineSpacing = 10;
    
    layout.footerReferenceSize = CGSizeMake(size.width, 100);
    layout.headerReferenceSize = CGSizeMake(size.width, 50);
    return [super initWithCollectionViewLayout:layout];
}

// 設(shè)置headerView和footerView的
