Show data from array to array labels in tableview

Question

i have the dictionary - dictTime: [Int:[Int]] and I'd like to show it in tableView in cell.

To show key in every cell - not a problem, but I'd like to show every element of value of dictionary in "own" UILabel, so I created [UILabel] and understand that count of UILabel in array must be equal count of elements in value of dictionary, but how to do it in func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell for showing for every row (row - it's key-[value])?

use numberOfRows(inSection section: Int) and return your count. — 200_OK

Who don't you just simply replace cell.textLabel?.text = indexPath.row by cell.textLabel?.text = dictTime[indexPath.row] in cellForRowAt ? — Toldy

@Niharika [1:[1,2,3], 2: [1,2,3]] and so I have two row (because 2 keys) and every row I'd like to have 3 labels at row and first label has text "1", next - "2", third - "3" — Vadim Nikolaev

Assuming your dictionary is like [Int1: [Int2]], that means:

dictTime.allKeys will give you array of all Int1
dictTime[Int1] will give you respective [Int2]

Example:

var dictTime = [1: [1,2], 2: [2,3], 3: [3,4]]

For showing these in a tableView:

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return dictTime.count
    }

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCellWithIdentifier("MyCell", forIndexPath: indexPath)
        let keys = Array (dictTime.keys)
        cell.textLabel?.text = String (keys[indexPath.row])
        cell.detailTextLabel?.text = String (dictTime[indexPath.row])

        return cell
    }

In func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell call an other function and pass your dictionary value to that function for example [1,2,3] also pass your tbaleviewcell to that function. Now in that function run a loop on your dictionary array [1,2,3] and one by one UILabel into your tableviewcell programmatically.

I am not sure I understand the problem. If you want to have as many rows as dictionary entries, use the following:

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return dictTime.count
}

If you want to have as many labels in your cell, as entries for each key in your dictionary, you need to implement a complicated solution.

I would suggest creating a "super cell" which has the maximum amount of labels, put them in a stach view, and hide them according to the number of entries.
