[英]NSInternalInconsistencyException with UITableViewController and a Storyboard-Pop
[英]UITableViewController: NSInternalInconsistencyException
搜索解決方案后,我無法解決此問題,我得到了以下代碼以列出核心數據中的數據:
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
}}
}
我有這樣的錯誤:
由於未捕獲的異常'NSInternalInconsistencyException'而終止應用程序,原因:'-[[UITableViewController loadView]加載了“ TuG-ju-H3E-view-l3X-mv-HmR”筆尖,但未獲取UITableView。 ***第一個調用堆棧:libc ++ abi.dylib:以NSException類型的未捕獲異常終止
我不知道該怎么辦,因為我嘗試了一切
您將您的類聲明為UITableViewController
在這種情況下,視圖出口必須連接到表格視圖。 但是,如果您想要一個包含UITableView
的視圖,則只需簡單地使控制器成為符合UITableViewDelegate
和UITableViewDataSource
協議的UIViewController
即可。
更改為
class ViewControllerClass: UIViewController, UITableViewDelegate, UITableViewDataSource, NSFetchedResultsControllerDelegate
