Usage

viewControllers

Type is [UIViewController], and element must have title.

import PageController

class CustomViewController: PageController {

    override func viewDidLoad() {
        super.viewDidLoad()

        viewControllers = createViewControllers()
    }

    func createViewControllers() -> [UIViewController] {
        let names = [
            "favorites",
            "recents",
            "contacts",
            "history",
            "more",
        ]

        return names.map { name -> UIViewController in
            let viewController = ContentViewController()
            viewController.title = name
            return viewController
        }
    }
}

MenuBar

Enable to change backgroundColor, frame. If you change MenuBarCell.height, then override frameForMenuBar and set height.

/// backgroudColor
menuBar.backgroundColor = UIColor.whiteColor().colorWithAlphaComponent(0.9)
/// skip to auto-select after scrolling
menuBar.isAutoSelectDidEndUserInteractionEnabled = false

/// frame, override this function
override var frameForMenuBar: CGRect {
    let frame = super.frameForMenuBar

    return CGRect(x: frame.minX, y: frame.minY, width: frame.width, height: 60)
}

MenuBarCell

Enable to use Custom Cell supported MenuBarCellable protocol:

public protocol MenuBarCellable {
    var index: Int { get set }
    func setTitle(_ title: String)
    func setHighlighted(_ highlighted: Bool)
    func prepareForReuse()
}

public func register(_ cellClass: MenuBarCellable) {
    guard let cellClass = cellClass as? UIView.Type else { fatalError() }
    self.cellClass = cellClass
}

public func register(_ nib: UINib) {
    self.nib = nib
}

MenuBarCellable

public protocol MenuBarCellable {

    // it's used by PageController
    var index: Int { get set }

    // it is used to set to Label.text, caused by deprecating MenuCell over 0.7
    func setTitle(_ title: String)

    // it's instead of `updateData` over 0.7,
    func setHighlighted(_ highlighted: Bool)

    // Called by the menu bar on creating the instance.
    func prepareForUse()

}
