  • Swift 3.x
  • iOS 8.0

Installation

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

pod "JExpandableTableView"

Features

  • Expandable cells
  • Allows to fetch cells asynchronously (refer tableView(_ tableView: JExpandableTableView, numberOfRowsInSection section: Int, callback: @escaping (Int) -> Void) method in Example)
  • Multple configaration for cell expansion and collapse
  • Easy integration through xib
  • Highly customizable - JExpandableTableView accepts any Header view and Custom cells which makes it very customizable similar to UITableView

Code Integration

Creating instance

  • Using interface builder, set class of any UIView to JExpandableTableView & create outlet in respective viewcontroller
    @IBOutlet weak var jtableView: JExpandableTableView!
  • Using interface builder, set class of any UIView to JExpandableTableView & create outlet in respective viewcontroller
    jtableView = JExpandableTableView(frame: <#T##CGRect#>)

Assign delegates, smilar to UITableView delegate

        jtableView.delegate = self
        jtableView.dataSource = self

Sample delegate methods given below, please refer Example app to get more information.

    func tableView(_ tableView: JExpandableTableView, numberOfRowsInSection section: Int, callback:  @escaping (Int) -> Void) {

        let sectionInfo = self.dataArray[section]

        if sectionInfo.cells.count != 0 {
            callback(sectionInfo.cells.count)
        }else{
            
            tableView.isUserInteractionEnabled = false
            SVProgressHUD.show(withStatus: "Loading chapters...")
            
            DispatchQueue.global().async {
                
                Thread.sleep(forTimeInterval: 2)
                DispatchQueue.main.sync {
                    tableView.isUserInteractionEnabled = true
                    SVProgressHUD.dismiss()
                    let sectionInfo = self.dataArray[section]
                    sectionInfo.cells.append(CellInfo("1. Prologue ",cellId: "TextCell"))
                    sectionInfo.cells.append(CellInfo("2. Bran I",cellId: "TextCell"))
                    sectionInfo.cells.append(CellInfo("3. Catelyn I",cellId: "TextCell"))
                    sectionInfo.cells.append(CellInfo("4. Daenerys I",cellId: "TextCell"))
                    sectionInfo.cells.append(CellInfo("5.  A Game of Thrones, very very long chapter beyond the wall",cellId: "TextCell"))
                    
                    callback(sectionInfo.cells.count)
                    
                }
            }
        }
    }
    
    func tableView(_ tableView: JExpandableTableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell{
        
        let section = self.dataArray[indexPath.section]
        let row = section.cells[indexPath.row]

        let cellId = row.cellId
        let cell = tableView.dequeueReusableCell(withIdentifier: cellId!, for: indexPath)
    
        cell.contentView.backgroundColor = UIColor.white
        let label = cell.viewWithTag(11) as? UILabel
        label?.text = row.text
        return cell
    }
    
    func numberOfSections(in tableView: JExpandableTableView) -> Int {
        
        return dataArray.count
    }
    
    func tableView(_ tableView: JExpandableTableView, viewForHeaderInSection section: Int) -> UIView? {
        
        let section = self.dataArray[section]
        let header = tableView.dequeueReusableHeaderFooterView(withIdentifier: "HeaderView")
        header?.contentView.backgroundColor = UIColor.groupTableViewBackground
        let label = header?.viewWithTag(11) as? UILabel
        label?.text = section.title
        return header
    }
