SplittableViewKit

A cell of IndexPath(row: 0, section: 0) in UITableView is automatically moved to left view when device rotated.

Usage

Please initialize SplittableTableView with initializer or Interface Builder. SplittableTableView.rightView is UITableView. Do not set delegate or dataSource directly to SplittableTableView.rightView. You must use SplittableTableView.delgate or SplittableTableView.dataSource.

let splittableTableView: SplittableTableView

splittableTableView.delegate = self
splittableTableView.dataSource = self
splittableTableView.rightView.register(UINib(nibName: "ThumbnailViewCell", bundle: nil),
                                       forCellReuseIdentifier: "ThumbnailViewCell")

SplittableViewKit is almost same as UITableView interface because SplittableTableViewDataSource adopted UITableViewDataSource and SplittableTableViewDelegate adopted UITableViewDelegate. func splittableContainerViewFor(topView: UIView, layoutType: LayoutType) -> UIView is only one difference. You should return a UIView that layouted top view. Layout patterns are LayoutType.left and LayoutType.fixedTop.

extension ViewController: SplittableTableViewDataSource {
    func splittableContainerViewFor(topView: UIView, layoutType: LayoutType) -> UIView {
        let view = UIView(frame: .zero)
        topView.translatesAutoresizingMaskIntoConstraints = false
        view.addSubview(topView)
        if layoutType == .left {
            NSLayoutConstraint.activate([
                view.leadingAnchor.constraint(equalTo: topView.leadingAnchor, constant: 0),
                view.trailingAnchor.constraint(equalTo: topView.trailingAnchor, constant: 0),
                view.centerYAnchor.constraint(equalTo: topView.centerYAnchor, constant: 0)
            ])
        } else {
            NSLayoutConstraint.activate([
                view.safeAreaLayoutGuide.topAnchor.constraint(equalTo: topView.topAnchor, constant: 0),
                view.leftAnchor.constraint(equalTo: topView.leftAnchor, constant: 0),
                view.rightAnchor.constraint(equalTo: topView.rightAnchor, constant: 0),
                view.bottomAnchor.constraint(equalTo: topView.bottomAnchor, constant: 0)
            ])
        }
        return view
    }
}

You can change fixed top or not with SplittableTableView.isFixedTop.

splittableTableView.isFixedTop = true

left	fixedTop

You can change ratio of leftView and rightView with SplittableTableView.ratio.

splittableTableView.ratio = .init(left: 1, right: 2)

left: 1, right: 1	left: 2, right: 1
