Melodeon

A simple subclass of UITableViewController which behaves like a melodeon.

Usage

Inherit MelodeonController and implement it just like you would on a normal UITableViewController.

  class TableViewController: MelodeonController {
    var firstList = ["Option One", "Option Two", "Option Three"]
    var secondList = ["Choice One", "Choice Two", "Choice Three", "Choice Four" ]
    var thirdList = ["Element One", "Element Two"]
   
    ...
    .....
    
  }

Provide your sections as array and override the sections property.

  override var sections:[Any] {
    return ["List A", "List B", "List C"]
  }

And provide the number of rows per section (this is required).

  override func numberOfRows(inSection section:Int) -> Int {
    switch section {
    case 0:
      return firstList.count
    case 1:
      return secondList.count
    case 2:
      return thirdList.count
    default:
      return 0
    }
  }
  

Optional:

You may implement your own header cell as long as it is of type MelodeonHeaderCell.

  override var headerClasses:[MelodeonHeaderCell.Type]? {
    return [TableHeaderCell.self, AnotherHeaderCell.self]
  }

You may also provide the section which will be expanded when the view is loaded.

  override var initialExpandedSection: Int {
    return 0
  }

You can control which header is interactive.

  override func header(_ header: MelodeonHeaderCell, shouldTapAtSection section: Int) -> Bool {
    if section == 1 {
      return false
    }
    return true
  }

Or handle the tap events.

  override func header(_ header: MelodeonHeaderCell, didTapAtSection section: Int) {
    // TODO: Implement header tap event here
  }
