UITableView load more when scrolling to bottom

Question

I would like to load more data and create additional cells when the user scrolls to the bottom of the table. I'm using JSON data and MySql.

func dataJsonFromURL(url:String)->NSArray {     if let data = NSData(contentsOfURL: NSURL(string: url)!) {         return ((try! NSJSONSerialization.JSONObjectWithData(data, options: [])) as! NSArray)     }     else{         return data     } }  func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {     let cell = tableView.dequeueReusableCellWithIdentifier("NCell", forIndexPath: indexPath) as! TableViewCell22      cell.backgroundColor = UIColor .clearColor()      let mindata = (data[indexPath.row] as! NSDictionary) } 

Answer 1

you have to use this method

override func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {             let lastElement = dataSource.count - 1             if indexPath.row == lastElement {                 // handle your logic here to get more items, add it to dataSource and reload tableview                 }             } 

Answer 2

Xcode 8, Swift 3

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {     let lastElement = dataSource.count - 1     if !loadingData && indexPath.row == lastElement {         indicator.startAnimating()         loadingData = true         loadMoreData()     } }
