I'm currently building my first app in Swift. I use Parse as database and want to show all the titles in table Recipes. I created an array for all the titles and add every time a title. But my tableView function doesn't update it (count = 0)
I think that's because I don't reload the tableView after I append a title to my array. But I get aan error if I add self.tableView.reloadData() --> Cannot invoke 'reloadData' with no arguments.
Can someone help me out? I tried so many things and looked everywhere on the internet but couldn't find an answer.
My code:
import UIKit
import Parse
import Bolts
class FirstViewController: UIViewController, UITableViewDelegate {
var titel = [String]()
var afbeelding = [UIImage]()
var afbeeldingFile = [PFFile]()
override func viewDidLoad() {
super.viewDidLoad()
var query = PFQuery(className:"Recipes")
query.findObjectsInBackgroundWithBlock {
(objects: [AnyObject]?, error: NSError?) -> Void in
if error == nil {
// The find succeeded.
println("Successfully retrieved \(objects!.count) scores.")
// Do something with the found objects
if let objects = objects as? [PFObject] {
for object in objects {
self.titel.append((object["titel"] as! String?)!)
println(self.titel)
self.tableView.reloadData() //THIS GIVES AN ERROR - Cannot invoke 'reloadData' with no arguments
}
}
} else {
// Log details of the failure
println("Error: \(error!) \(error!.userInfo!)")
}
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return titel.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! Cell
cell.gerechtTitel.text = titel[indexPath.row]
return cell
}
}
Hope you guys can help me out :)
