iOS Swift: Pass data from ViewController to UITableViewCell - ios

Question

I'm trying to pass data from a ViewController to a custom UITableViewCell but it's not working. When I print data from ViewController.swift everything is in tact but when I print data from CustomCell.swift the array is empty. Here is my code:
ViewController.swift
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(kCellIdentifier) as! CustomCell
cell.data = data[indexPath.row]
return cell
}
CustomCell.swift
class CustomCell: UITableViewCell {
var data = [CKRecord]()
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
println(data)
}
}

Answer 1

You can perform that simply by using didSet closure, change your code to the following:
class CustomCell: UITableViewCell {
var data = [Int]() {
didSet{
print(data)
}
}
var id: Int {
didSet{
loadById(id)
}
}
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
// This block runs before data being set! Rather call your code from didSet{} closure..
}
func loadById(_ id: Int) {
// Your code goes here
}
}
And from your ViewController pass the data:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell") as! CustomCell
cell.data = data[indexPath.row]
cell.id = 1 // pass here any variable you need
return cell
}
And it should work

Answer 2

in CustomCell.swift, you just have to set the content such as: UILabel, UIImage, etc.
Rather than explaining here the whole things, I think you better follow the tutorial here:
