reload cell data in table view with Swift

Question

how is it possible to reload data for a cell in my table view? I want to do a request to my Server and the server responses JSON. At the moment I implemented the request and the response handling and I can show the data in my cells. But I want that the server only responses maybe ten datasets. When I scroll to the end of the table view with my ten cells in the app I want to do the next request to my server and the server delivers the next ten datasets and so on. I work with Swift as the programming language.

you can get Array of visible Cell by using TableView Function tableView.visibleRows() or You Can Get IndexPath of Visible Rows By tableView.indexPathsForVisibleRows() ! and then you can reload table by tableView.reloadData() Function! — Saurabh Prajapati, Nov 03 '14 at 08:30

You can use self.tableView.reloadData() in order to reload your entire table or self.tableView.reloadRowsAtIndexPaths(paths, withRowAnimation: UITableViewRowAnimation.None) in order to reload a specific cell.

yes - that's why the code I gave is in swift... I'll add the "self." just to make sure. – YogevSitton Nov 03 '14 at 07:31

I too use `self` to indicate it's an ivar ;) for me that makes it much more clear. – HAS Nov 03 '14 at 08:32
@YogevSitton self.tableView.reloadRowsAtIndexPaths(paths, withRowAnimation: UITableViewRowAnimation.None)...I have tableView from which I want to add a new cell at 0 index....How can I do that, I mean..I not getting how to create a indexpath object with specific row and column, as there is no constructor of that type? – Maninder Singh Jul 09 '17 at 23:23

Try this...

Swift 2.0

dispatch_async(dispatch_get_main_queue(), { () -> Void in
   self.tableView.reloadData()
})

Swift 3.0

DispatchQueue.main.async {
    self.tableview.reloadData()
}

If you're calling reloadData() inside of a block, you have to dispatch it so that it's on the main_queue – NSCoder Mar 29 '16 at 10:50
