How do i load item 5 per 5? in PFQueryTableViewController - ios

Question

Im using PFQueryTableViewController to load all my data from parse.
Currently it loads all the data at once, so in the future if i have many data it will mess up the user experience of users. How do i load it 5 per 5 whenever I scrolled down?
Here's the code
import UIKit
import Parse
import ParseUI
class MainViewTable: PFQueryTableViewController {
// Initialise the PFQueryTable tableview
override init(style: UITableViewStyle, className: String!) {
super.init(style: style, className: className)
}
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.parseClassName = "product"
self.textKey = "createdAt"
self.pullToRefreshEnabled = true
self.paginationEnabled = false
}
override func queryForTable() -> PFQuery {
var query = PFQuery(className: "product")
query.orderByDescending("createdAt")
return query
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject?) -> PFTableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("CustomCell") as! CustomTableViewCell!
if cell == nil {
cell = CustomTableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "CustomCell")
}
if let titleName = object?["title"] as? String {
cell.title.text = titleName
}
if let priceTitle = object?["price"] as? Int {
cell.price.text = String(priceTitle)
println(cell.price.text! + "Price")
}
return cell
}
override func viewDidAppear(animated: Bool) {
// Refresh the table to ensure any data changes are displayed
tableView.reloadData()
}
}
