After searching for solution I cant resolve this issue, I have this code to list the data from core data:
import UIKit
import CoreData
class ViewControllerClass: UITableViewController, NSFetchedResultsControllerDelegate{
let managedObjectContext = (UIApplication.sharedApplication().delegate as! AppDelegate).managedObjectContext
var fetchedResultController: NSFetchedResultsController = NSFetchedResultsController()
var intermedioLat:String = ""
var intermedioLong:String = ""
@IBOutlet weak var listagem: UITableView!
var velocidade = ["40","50","70","90","100","120"]
func textFieldSouldReturn (textField: UITextField) -> Bool{
textField.resignFirstResponder()
return true
}
override func viewDidLoad() {
print(intermedioLat)
print(intermedioLong)
fetchedResultController = getFetchedResultController()
fetchedResultController.delegate = self
fetchedResultController.performFetch(nil)
super.viewDidLoad()
// Do any additional setup after loading the view.
}
func getFetchedResultController() -> NSFetchedResultsController {
fetchedResultController = NSFetchedResultsController(fetchRequest: taskFetchRequest(), managedObjectContext: managedObjectContext!, sectionNameKeyPath: nil, cacheName: nil)
return fetchedResultController
}
func taskFetchRequest() -> NSFetchRequest {
let fetchRequest = NSFetchRequest(entityName: "Radar")
let sortDescriptor = NSSortDescriptor(key: "descricao", ascending: true)
fetchRequest.sortDescriptors = [sortDescriptor]
return fetchRequest
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
let numberOfSections = fetchedResultController.sections?.count
return numberOfSections!
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
let numberOfRowsInSection = fetchedResultController.sections?[section].numberOfObjects
return numberOfRowsInSection!
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("Celula", forIndexPath: indexPath) as! UITableViewCell
let task = fetchedResultController.objectAtIndexPath(indexPath) as! Radar
cell.textLabel?.text = task.descricao
return cell
}
override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
let managedObject:NSManagedObject = fetchedResultController.objectAtIndexPath(indexPath) as! NSManagedObject
managedObjectContext?.deleteObject(managedObject)
managedObjectContext?.save(nil)
}
func controllerDidChangeContent(controller: NSFetchedResultsController) {
tableView.reloadData()
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "fromEventTableToAddEvent"{
var enviaInterLat : adicionarRadar = segue.destinationViewController as! adicionarRadar
enviaInterLat.latitude = intermedioLat
var enviaInterLong : adicionarRadar = segue.destinationViewController as! adicionarRadar
enviaInterLong.longitude = intermedioLong
}}
}
and I have a error like this:
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "TuG-ju-H3E-view-l3X-mv-HmR" nib but didn't get a UITableView.' *** First throw call stack: libc++abi.dylib: terminating with uncaught exception of type NSException
I dont know what more to do because I try everything
You declare your class as a UITableViewController
in this case the view outlet must be connected to the table view. However if you want a view that contains a UITableView
then simple make the controller a UIViewController
which conforms to the UITableViewDelegate
and UITableViewDataSource
protocols and this will go away.
Change it to
class ViewControllerClass: UIViewController, UITableViewDelegate, UITableViewDataSource, NSFetchedResultsControllerDelegate
