I did this for fetching data and showing it in a table view but it's not showing anything.
I used this code:
import UIKit
import Parse
import Bolts
class Parsedata: UIViewController, UITableViewDelegate, UITableViewDataSource {
//@IBOutlet var NTableView: UITableView!
@IBOutlet var NTableView: UITableView!
var NArray:[String] = [String]()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.NTableView.delegate = self
self.NTableView.dataSource = self
// retrieve notification from parse
self.RetrieveN()
NSLog("Done with it")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func RetrieveN () {
//create a pfquery
var query:PFQuery = PFQuery(className: "Notification")
//call findobject in background
query.findObjectsInBackgroundWithBlock { (objects, error) -> Void in
//clear the Narray
self.NArray = [String]()
//loop through the objects array
for Nobject in objects!{
//retrieve the text column value of each PFobject
let Ntext:String? = (Nobject as! PFObject) ["Text"] as? String
// assign it into your Narray
if Ntext != nil {
self.NArray.append(Ntext!)
}
}
if error == nil {
// The find succeeded.
print("Successfully retrieved \(objects!.count) Notifications.")}
//reload the table view
self.NTableView.reloadData()
}
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = self.NTableView.dequeueReusableCellWithIdentifier("NCell") as UITableViewCell?
cell?.textLabel?.text = self.NArray[indexPath.row]
return cell!
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return NArray.count
}
}
It's working fine because it's showing that 3 objects were retrieved on the LOG container.
