Ich benutze swift2.

Wollen sectionArr als Kopf

let sectionArr = ["animal", "bird"] //section 
    let animalArr = ["dog", "cat"] 
    let birdArr = ["crow", "cock"] 

override func viewDidLoad() { 
    super.viewDidLoad() 
    // Do any additional setup after loading the view, typically from a nib. 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated. 
} 

func numberOfSectionsInTableView(tableView: UITableView) -> Int { 
    return sectionArr.count 
} 

// Header-Abschnitt

func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? { 
    let headerView = UIView() 
    headerView.frame = CGRectMake(0, 0, tableView.frame.size.width, 80) 
    // headerView.backgroundColor = [UIColor, clearColor]; 
    let lblTitle = UILabel() 
    lblTitle.frame = CGRectMake(0, 0, tableView.frame.size.width, 40) 
    lblTitle.text = sectionArr[section] 
    headerView.addSubview(lblTitle) 
    return headerView 
    } 


func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
     if section == 0 { 
      return animalArr.count

      return birdArr.count 
     } 
    } 

// Anzeige vi nehmen ew Zelle

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

ich meine Antwort bekam! Hier habe ich meinen Code von Collaps und exapnd Zelle in tableview.Hope seine Hilfe teilen!

class ViewController: UIViewController,UITableViewDataSource,UITableViewDelegate { 

    let sectionArr = ["Animal", "Bird"] 
    let animalArr = ["dog", "cat"] 
    let birdArr = ["crow", "cock"] 
    var isBool = false 
    var sec = 0 

    @IBOutlet weak var tableview: UITableView! 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     tableview.reloadData() 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 

    func numberOfSectionsInTableView(tableView: UITableView) -> Int { 
     return sectionArr.count 
    } 

    func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? { 
     let headerView = UIView() 
     headerView.frame = CGRectMake(0, 0, tableview.frame.size.width, 80) 
     //create lable dynamically 
     let lblTitle = UILabel() 
     lblTitle.frame = CGRectMake(0, 0, tableview.frame.size.width, 40) 
     lblTitle.text = sectionArr[section] 
     headerView.addSubview(lblTitle) 

     //create button dynamically 
     let btn: UIButton = UIButton(frame: CGRectMake(0, 0, tableview.frame.size.width, 40)) 
     btn.setTitle(sectionArr[section], forState: UIControlState.Normal) 
     btn.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside) 
     btn.tag = section    // change tag property 
     headerView.addSubview(btn) 
     return headerView 
    } 

    func buttonAction(sender: UIButton!) 
    { 
     if isBool == false { 
      sec = sender.tag 
      isBool = true 
      tableview.reloadData() 
     } else { 
      sec = 0 
      isBool = false 
      tableview.reloadData() 
     } 
    } 

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
     if section == 0 { 
      if isBool && sec == 0 { 
       return animalArr.count 
      } else { 
       return 0 
      } 
     } else{ 
      if isBool && sec == 1 { 
       return birdArr.count 
      } else { 
       return 0 
      } 

     } 
    } 

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
    let cell1:UITableViewCell=UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "cell") 

     if(indexPath.section == 0) 
     { 
      cell1.textLabel!.text=animalArr[indexPath.row] 
     } 
     else 
     { 
      cell1.textLabel!.text=birdArr[indexPath.row] 
     } 
     return cell1 
    } 
}
