Description

Standard mode with flexible item width

Segmented control mode

Infinite mode with fixed item width

Customization

PagingMenuControllerCustomizable

• default page index to show as a first view

defaultPage: Int

• duration for paging view animation

animationDuration: TimeInterval

• isScrollEnabled for paging view. Set false in case of using swipe-to-delete on your table view

isScrollEnabled: Bool

• background color for paging view

backgroundColor: UIColor

• number of lazy loading pages

lazyLoadingPage: LazyLoadingPage
public enum LazyLoadingPage {
    case one // Currently sets false to isScrollEnabled at this moment. Should be fixed in the future.
    case three
    case all // Currently not available for Infinite mode
}

• a set of menu controller

menuControllerSet: MenuControllerSet
public enum MenuControllerSet {
        case single
        case multiple
    }

• component type of PagingMenuController

componentType: ComponentType
public enum ComponentType {
    case menuView(menuOptions: MenuViewCustomizable)
    case pagingController(pagingControllers: [UIViewController])
    case all(menuOptions: MenuViewCustomizable, pagingControllers: [UIViewController])
}

MenuViewCustomizable

• background color for menu view

backgroundColor: UIColor

• background color for selected menu item

selectedBackgroundColor: UIColor

• height for menu view

height: CGFloat

• duration for menu view animation

animationDuration: TimeInterval

• decelerating rate for menu view

deceleratingRate: CGFloat

• menu item position

menuSelectedItemCenter: Bool

• menu mode and scrolling mode

displayMode: MenuDisplayMode

public enum MenuDisplayMode {
    case standard(widthMode: MenuItemWidthMode, centerItem: Bool, scrollingMode: MenuScrollingMode)
    case segmentedControl
    case infinite(widthMode: MenuItemWidthMode, scrollingMode: MenuScrollingMode) // Requires three paging views at least
}

public enum MenuItemWidthMode {
    case flexible
    case fixed(width: CGFloat)
}

public enum MenuScrollingMode {
  case scrollEnabled
  case scrollEnabledAndBouces
  case pagingEnabled
}

if centerItem is true, selected menu item is always on center

if MenuScrollingMode is ScrollEnabled or ScrollEnabledAndBouces, menu view allows scrolling to select any menu item
if MenuScrollingMode is PagingEnabled, menu item should be selected one by one

• menu item focus mode

focusMode: MenuFocusMode
public enum MenuFocusMode {
    case none
    case underline(height: CGFloat, color: UIColor, horizontalPadding: CGFloat, verticalPadding: CGFloat)
    case roundRect(radius: CGFloat, horizontalPadding: CGFloat, verticalPadding: CGFloat, selectedColor: UIColor)
}

• dummy item view number for Infinite mode

dummyItemViewsSet: Int

• menu position

menuPosition: MenuPosition

public enum MenuPosition {
    case top
    case bottom
}

• divider image to display right aligned in each menu item

dividerImage: UIImage?

MenuItemViewCustomizable

• horizontal margin for menu item

horizontalMargin: CGFloat

• menu item mode

displayMode: MenuItemDisplayMode
public enum MenuItemDisplayMode {
    case text(title: MenuItemText)
    case multilineText(title: MenuItemText, description: MenuItemText)
    case image(image: UIImage, selectedImage: UIImage?)
    case custom(view: UIView)
}

Usage

import PagingMenuController to use PagingMenuController in your file.

Using Storyboard

struct MenuItem1: MenuItemViewCustomizable {}
struct MenuItem2: MenuItemViewCustomizable {}

struct MenuOptions: MenuViewCustomizable {
    var itemsOptions: [MenuItemViewCustomizable] {
        return [MenuItem1(), MenuItem2()]
    }
}

struct PagingMenuOptions: PagingMenuControllerCustomizable {
    var componentType: ComponentType {
        return .all(menuOptions: MenuOptions(), pagingControllers: [UIViewController(), UIViewController()])
    }
}

let pagingMenuController = self.childViewControllers.first as! PagingMenuController
pagingMenuController.setup(options)
pagingMenuController.onMove = { state in
    switch state {
    case let .willMoveController(menuController, previousMenuController):
        print(previousMenuController)
        print(menuController)
    case let .didMoveController(menuController, previousMenuController):
        print(previousMenuController)
        print(menuController)
    case let .willMoveItem(menuItemView, previousMenuItemView):
        print(previousMenuItemView)
        print(menuItemView)
    case let .didMoveItem(menuItemView, previousMenuItemView):
        print(previousMenuItemView)
        print(menuItemView)
    case .didScrollStart:
        print("Scroll start")
    case .didScrollEnd:
        print("Scroll end")
    }
}

• You should add ContainerView into your view controller’s view and set PagingMenuController as the embedded view controller’s class

See PagingMenuControllerDemo target in demo project for more details

Coding only

struct MenuItem1: MenuItemViewCustomizable {}
struct MenuItem2: MenuItemViewCustomizable {}

struct MenuOptions: MenuViewCustomizable {
    var itemsOptions: [MenuItemViewCustomizable] {
        return [MenuItem1(), MenuItem2()]
    }
}

struct PagingMenuOptions: PagingMenuControllerCustomizable {
    var componentType: ComponentType {
        return .all(menuOptions: MenuOptions(), pagingControllers: [UIViewController(), UIViewController()])
    }
}

let options = PagingMenuOptions()
let pagingMenuController = PagingMenuController(options: options)

addChildViewController(pagingMenuController)
view.addSubview(pagingMenuController.view)
pagingMenuController.didMove(toParentViewController: self)

See PagingMenuControllerDemo2 target in demo project for more details

Menu move handler (optional)

public enum MenuMoveState {
    case willMoveController(to: UIViewController, from: UIViewController)
    case didMoveController(to: UIViewController, from: UIViewController)
    case willMoveItem(to: MenuItemView, from: MenuItemView)
    case didMoveItem(to: MenuItemView, from: MenuItemView)
    case didScrollStart
    case didScrollEnd
}

pagingMenuController.onMove = { state in
    switch state {
    case let .willMoveController(menuController, previousMenuController):
        print(previousMenuController)
        print(menuController)
    case let .didMoveController(menuController, previousMenuController):
        print(previousMenuController)
        print(menuController)
    case let .willMoveItem(menuItemView, previousMenuItemView):
        print(previousMenuItemView)
        print(menuItemView)
    case let .didMoveItem(menuItemView, previousMenuItemView):
        print(previousMenuItemView)
        print(menuItemView)
    case .didScrollStart:
        print("Scroll start")
    case .didScrollEnd:
        print("Scroll end")
    }
}

Moving to a menu tag programmatically

// if you pass a nonexistent page number, it'll be ignored
pagingMenuController.move(toPage: 1, animated: true)

Changing PagingMenuController’s option

Call setup method with new options again.
It creates a new paging menu controller. Do not forget to cleanup properties in child view controller.
