iOS swift5 轮播图 UITableView横向（水平方向）滚动

1.UITableView横向滚动

• 核心代码

tableView.transform = CGAffineTransformMakeRotation(-Double.pi / 2)

cell.transform = CGAffineTransformMakeRotation(.pi / 2)

2.轮播图(代码)

CarouselCell

        setupUI()
    }
    
    required init?(coder: NSCoder) {
    
    
        fatalError("init(coder:) has not been implemented")
    }
