Xcode Trigger Action after Cell is Clicked in Swift - ios

Question

I am relatively new to programming in general (this is my first year learning it at school) so please explain in as easy a way to grasp as possible.
I am using UITableViewController to create a table view and I want to be able to add a string to a cell if it is empty (I think I have to add it to the array "phrases", but correct me if I am wrong) and display the contents of the cell if it contains a string. I know it has something to do with NSIndexPath but I don't know where to put the code.
class MyPhrases: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
var phrases = []
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return phrases.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell")!
cell.textLabel
return cell
}
}
Sorry if I messed up the formatting of the code this is my first question.
Thanks in advance.

Answer 1

You are correct, you have to declare your array with phrases strings:
var phrases = ["welcome to stackoverflow", "second phrase", "third phrase"]
And change your cellForRowAtIndexPath method like this:
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell")!
cell.textLabel.text = phrases[indexPath.row]
return cell
}
Index path describes the position of cell in table view. It has two important properties: row and section. Since your table view has only one section, you get the phrase to display from array by row number.

Answer 2

I think you need
cell.textLabel.text = phrases[indexPath.row]
but you will also need some code elsewhere to populate the array. for testing, you could try initialising the array - just to make sure you're seeing something in the tableView. You can initialise the array like this
var phrases = ["first", "second", "third"]
