Question

Setup (Swift 1.2 / iOS 8.4):

I have UITableView custom cell (identifier = Cell) inside UIViewController. Have two buttons (increment/decrement count) and a label (di

Answer 1

I have never seen anything like this before so I am not sure if this will be the correct way to do. But I got the intended functionality using the bellow code:

For people who find it difficult to understand: The only problem we have in this is to refer to the TableView Cell. Once you figure out a way to refer the cell, you can interact with the cell components.

func addBtn(sender: AnyObject) -> Int {
    let button: UIButton = sender as! UIButton

    let indexPath = NSIndexPath(forRow: sender.tag, inSection: 0) // This defines what indexPath is which is used later to define a cell
    let cell = tableView.cellForRowAtIndexPath(indexPath) as! FoodTypeTableViewCell! // This is where the magic happens - reference to the cell

    count = 1 + count
    println(count)
    cell.countLabel.text = "\(count)" // Once you have the reference to the cell, just use the traditional way of setting up the objects inside the cell.
    return count
}

func subBtn(sender: AnyObject) -> Int {
    let button: UIButton = sender as! UIButton

    let indexPath = NSIndexPath(forRow: sender.tag, inSection: 0)
    let cell = tableView.cellForRowAtIndexPath(indexPath) as! FoodTypeTableViewCell!

    if count == 0 {
        println("Count zero")
    } else {
        count = count - 1
    }

    cell.countLabel.text = "\(count)"
    println(count)
    return count
}

I hope someone will benefit from this.

PLEASE CORRECT ME IF THERE IS SOME PROBLEM IN THIS SOLUTION OR THERE IS A BETTER/PROPER WAY TO DO THIS.
