TableViewDiffableSection

Undocumented

Example

• Define a Cell Model

struct StringCellModel:  Hashable  {
    let uniqueID: String
    let text: String

    // Defines uniqueness of the model
    func hash(into hasher: inout Hasher) {
        hasher.combine(uniqueID)
    }

    // Defines dynamic context of the model
    static func == (lhs: Self, rhs: Self) -> Bool {
        lhs.text == rhs.text
    }
}

• Define a Cell

final class StringCell: UITableViewCell, ReusableCell, Configurable {
    typealias Model = StringCellModel

    func configure(with model: StringCellModel) {
        textLabel?.text = "ID: \(model.uniqueID): \(model.text)"
        selectionStyle = .none
    }
}

• create a TableViewRow

let model = StringCellModel(uniqueID: ID, text: title)
let row = TableViewRow<StringCell>(model: model,
                                   onTap: { debugPrint("tapped with \($0)")})
// add rows if need
row.addRowLeadingActions(leadingActions)
row.addRowTrailingActions(trailingActions)

• Add the row to the cell

let updates = TableViewDiffableSection(id: "SectionID here")
updates.addRows([row])

Method to add a header to the section

Usage Example

• Create a ReusableView

 final class TestReusableView: ReusableView, Configurable {

     let label: UILabel
     override init(reuseIdentifier: String?) {
         // Init and Configure UILabel

         super.init(reuseIdentifier: reuseIdentifier)
     }

     required init?(coder aDecoder: NSCoder) {
         super.init(coder: aDecoder)
     }

     func configure(with txt: String) {
         label.text = txt
     }
 }

• Create a header

 let text = "My custom section"
 let footer = ImmutableHeaderFooterProvider<TestReusableView>(model: text)

• Attach the header to a TableViewDiffableSection

 let updates = TableViewDiffableSection(id: "SectionID here")
 updates.addHeader(header)

Method to add a footer to the section

Usage Example

• Create a ReusableView

final class TestReusableView: ReusableView, Configurable {

    let label: UILabel
    override init(reuseIdentifier: String?) {
        // Init and Configure UILabel

        super.init(reuseIdentifier: reuseIdentifier)
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    func configure(with txt: String) {
        label.text = txt
    }
}

• Create a header

let text = "My custom section"
let footer = ImmutableHeaderFooterProvider<TestReusableView>(model: text)

• Attach the header to a TableViewDiffableSection

let updates = TableViewDiffableSection(id: "SectionID here")
updates.addHeader(footer)

Undocumented

Provides settings for the sections like

• row animations
• section animations
• header view provider
• footer view provider
• flag is the section is collapsed
