I made an app with Table View and Segmented Control, and this is my first time. I'm using some code and some tutorials, but It's not working. When I run my app It's crashing and it's showing this Error in logs:
MyApplication[4928:336085] * Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key tableView.'

libc++abi.dylib: terminating with uncaught exception of type NSException
The code that I used is:
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
let foodList:[String] = ["Bread", "Meat", "Pizza", "Other"]
let drinkList:[String] = ["Water", "Soda", "Juice", "Other"]
#IBOutlet weak var mySegmentedControl: UISegmentedControl!
#IBOutlet weak var myTableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
var returnValue = 0
switch(mySegmentedControl.selectedSegmentIndex) {
case 0:
returnValue = foodList.count
break
case 1:
returnValue = drinkList.count
break
default:
break
}
return returnValue
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let myCell = tableView.dequeueReusableCellWithIdentifier("myCells", forIndexPath: indexPath)
switch(mySegmentedControl.selectedSegmentIndex) {
case 0:
myCell.textLabel!.text = foodList[indexPath.row]
break
case 1:
myCell.textLabel!.text = drinkList[indexPath.row]
break
default:
break
}
return myCell
}
#IBAction func segmentedControlActionChanged(sender: AnyObject) {
myTableView.reloadData()
}
Here is main.Storyboard
I checked the code many times, but it's not working. First I had to use only Table View, watching this tutorial (https://www.youtube.com/watch?v=ABVLSF3Vqdg) I thought it will work to use Segmented Control as in tutorial. But still doesn't work. Same code, same error.
Can someone help me ?

Answer 1

You have your storyboard set up to expect an outlet called tableView but the actual outlet name is myTableView.
If you delete the connection in the storyboard and reconnect to the right variable name, it should fix the problem.

Answer 2

Any chance that you changed the name of your table view from "tableView" to "myTableView" at some point?
