Retrive all objects from Parse and then print in a Custom TableView? - ios

Question

I tried everything and I cant solve this, maybe im too tired to see, idk.
What i want is to retrive all objects from parse and list them in a tableview. So each row in the tableview must represent a row in the Parse Class. Objective: Show all the restaurants available.
Right now i can get all the objects from the Parse Class, but shows the same title on all table rows.
Here is the output (as you can see, always show the same name: "Renato" because its the last one that is retrived)
My code:
import UIKit
import Parse
class ListaTableViewController: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Uncomment the following line to preserve selection between presentations
// self.clearsSelectionOnViewWillAppear = false
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Potentially incomplete method implementation.
// Return the number of sections.
return 3
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete method implementation.
// Return the number of rows in the section.
return 1
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> ListaTableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! ListaTableViewCell
var query = PFQuery(className:"Restaurantes")
query.findObjectsInBackgroundWithBlock {
(objects: [AnyObject]?, error: NSError?) -> Void in
if error == nil {
// The find succeeded.
println("Successfully retrieved \(objects!.count) Restaurantes.")
// Do something with the found objects
if let objects = objects as? [PFObject] {
for object in objects {
cell.textCell.text = object["nome"] as? String
println(object.objectId)
}
}
} else {
// Log details of the failure
println("Error: \(error!) \(error!.userInfo!)")
}
}
//cell.textCell.text = "Hello world"
cell.imageBg.image = UIImage(named: "www.maisturismo.jpg")
return cell
}
}
Println Output

You are currently iterating through the whole objects array which will show always the last
for object in objects {
cell.textCell.text = object["nome"] as? String
}
You need to do it like this
if let objects = objects as? [PFObject] {
cell.textCell.text = objects[indexPath.row]["nome"] as? String
}
Also you should take another "way" of using the UITableViewController Subclass... Take a look, I quickly wired you up some code to see how you should do it...
