Swift - Override functions in UIViewController vs UITableViewController

Question

When I use the UITableViewController to create a tableView, you get a lot of override functions, but when you use a regular UIViewController you get an error when using these same override functions and you are forced to change them to regular functions. I believe this is why my core data won't load into my cells, and tried to use the viewDidLoad function to get my data to load.

I know my code should work since all I'm trying to do is transfer all my code from a UITableViewController to a UIViewController, and my code worked in my UITableViewController.

My effort so far:

override func viewDidLoad() {

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        // Configure the cell...

        let CellID:NSString = "CELL"

        var cell:UITableViewCell = tableView.dequeueReusableCellWithIdentifier(CellID) as UITableViewCell

        if let ip = indexPath as Optional {

            var data:NSManagedObject = myList[ip.row] as NSManagedObject
            cell.textLabel!.text = data.valueForKeyPath("username") as? String
        }

        return cell
    }
}

Are the override functions the reason my cells are empty, or are there other aspects when using a regular UIViewController to show a tableView?

Any suggestions would be appreciated.

Answer 1

(1) You have to add UITableViewDelegate to the class in order to access the delegate methods, ex:

class ViewController: UIViewController, UITableViewDelegate {

After adding the UITableViewDelegate to the class, your UITableView delegate functions should auto-complete.

Also, make sure to set the UITableView 's delegate to self in order to have the delegate methods populate the table.

(2) Right now, your cellForRowAtIndexPath method is within your viewDidLoad . Move it so it's not contained within any other method.
