Installation

ABExpandableView is available through CocoaPods. To install it, simply add the following line to your Podfile:

Usage

First, import

ABExpandableView
to your project.

You should have 2 kinds of model objects to use this view that one of them should be section and the other one should be row.

Consider, Section and Row classes are your objects.

class Section: SectionItem {
    var identifier: String!
    var name: String!

var expanded: Bool = true

var rows: [RowItem] = [RowItem]()
var rawRows: [RowItem] = [RowItem]() {
    didSet {
        rows = rawRows
    }
}
var selectedRows: [RowItem] = [RowItem]()

}

class Row: RowItem { var identifier: String! var name: String! }

class MockDataProvider {

class func createMockData() -> [SectionItem] {
    var array = [SectionItem]()

    let izmir = City()
    izmir.identifier = "35"
    izmir.name = "İzmir"
    let bornova = Town(identifier: "1", name: "Bornova")
    let urla = Town(identifier: "2", name: "Urla")
    let konak = Town(identifier: "3", name: "Konak")
    let izmirRawRows = [bornova, urla, konak]
    izmir.rawRows = izmirRawRows
    array.append(izmir)

    let istanbul = City()
    istanbul.identifier = "34"
    istanbul.name = "İstanbul"
    let kadikoy = Town(identifier: "4", name: "Kadıköy")
    let maltepe = Town(identifier: "5", name: "Maltepe")
    let beykoz = Town(identifier: "6", name: "Beykoz")
    let istanbulRawRows = [kadikoy, maltepe, beykoz]
    istanbul.rawRows = istanbulRawRows
    array.append(istanbul)

    return array
}

}

After you create your models, you should open ABExpandableView with injecting those model array.

@IBAction func buttonTapped(_ sender: Any) {
        let cities = MockDataProvider.createMockData()
        let expandableSectionsViewModel = ExpandableSectionsViewModel(cities)
        let expandableSectionViewController = ExpandableSectionsViewController.newInstance(expandableSectionsViewModel)
        expandableSectionViewController.title = "Choose Town(s)"
        expandableSectionViewController.delegate = self
        self.navigationController?.pushViewController(expandableSectionViewController, animated: true)
    }

Here, let ABExpandableView handle the rest.

One last thing; You can get selected items using the delegation;

    func didSelectItems(_ items: [RowItem]) {
        let names = items.flatMap { $0.name }.joined(separator: ", ")
        // "Bornova, Kadıköy"
    }
