How to solve "Reserved viewController compliance for UIScrollViewDelegate protocol in fast?"

Question

I am new to stackOverflow and learn fast. I get the error "Redundant compliance of viewController to the protocol when working with Stretch headers.UIScrollViewDelegate. I indicate my code below, please correct any.

class ViewController: UITableViewController , UIScrollViewDelegate {
    private let kTableHeaderHeight : CGFloat = 300.0
    // Using Implicitly Unwrapped Optional, UIView!
    var headerView:UIView!

    let items = [
    NewsItem(category: .World, summary: "Climate Change protests, Need to preserve our Ecosysytem"),
    NewsItem(category: .India, summary: "Climate Change protests, Need to preserve our Ecosysytem"),
    NewsItem(category: .America, summary: "Climate Change protests,Need to preserve our Ecosysytem"),
    NewsItem(category: .Japan, summary: "Climate Change protests, Need to preserve our Ecosysytem"),
    NewsItem(category: .China, summary: "Climate Change protests, Need to preserve our Ecosysytem"),
    NewsItem(category: .Nepal, summary: "Climate Change protests, Need to preserve our Ecosysytem")]
    override func viewDidLoad() {
        super.viewDidLoad()
        headerView = tableView.tableHeaderView
        tableView.tableHeaderView = nil
        tableView.addSubview(headerView)
   tableView.contentInset = UIEdgeInsetsMake(kTableHeaderHeight, 0, 0, 0)
        tableView.contentOffset = CGPointMake(0, -kTableHeaderHeight)
        updateHeaderView()
    }
    func updateHeaderView(){
        var HeaderRect = CGRectMake(0,-kTableHeaderHeight, tableView.bounds.width, kTableHeaderHeight)

        if tableView.contentOffset.y < -kTableHeaderHeight{
            HeaderRect.origin.y = tableView.contentOffset.y
            HeaderRect.size.height = -tableView.contentOffset.y
        }
        headerView.frame = HeaderRect
    }
    override func didReceiveMemoryWarning() {enter code here
        super.didReceiveMemoryWarning()   
    }
    override func scrollViewDidScroll(scrollView: UIScrollView) {
        updateHeaderView()
    }
    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return items.count
    }
    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let item = items[indexPath.row]
let cell = tableView.dequeueReusableCellWithIdentifier("Cell" forIndexPath: indexPath) as! NewsItemTableViewCell
        cell.newsItem = item
 return cell          
    }

Answer 1

You get this error because your class ViewControllerconforms to the protocol in UIScrollViewDelegatetwo ways. UITableViewControlleralready conforms to this protocol, you do not need to add it again. So remove UIScrollViewDelegatefrom there, you are good.

UITableViewController UITableViewDelegate, UIScrollViewDelegate.

class ViewController: UITableViewController{
}

Answer 2

, UITableViewController , Scrollview. UIScrollViewDelegate, .
