我是新的stackOverflow和学习迅速。我得到错误 ”冗余一致性viewController协议处理Stretch headers.UIScrollViewDelegate。我在下面指定我的代码。请纠正任何一个。如何解决错误“冗余一致性viewController协议UIScrollViewDelegate在swift?
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
}
