I need index path for both section and row in tableview, I got a index for row but not for the section - ios

Question

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "TableViewCellrow", for: indexPath) as! TableViewCellrow
cell.imgView.image = UIImage(named: namearr[indexPath.section].1[indexPath.row])
cell.lblName.text = namearr[indexPath.section].1[indexPath.row]
cell.btnCross.tag = indexPath.row
cell.btnCross.addTarget(self, action: #selector(cutt), for: .touchUpInside)

Answer 1

If I got it right, you wanna store both row and section in button tag so it can be accessed in cutt function.
You can do it like this:
cell.btnCross.tag = (indexPath.section << 16) | indexPath.row
And then retrieve it in cutt func like this:
let section = button.tag >> 16
let row = button.tag & ((1 << 16) - 1)
Also note, that storing data in UIView tag is not the best solution in terms of performance.
UIKit implements tags using objc_get/setAssociatedObject(), meaning that every time you set or get a tag, you’re doing a dictionary lookup. Check out more here
An other option, which is I'd say is better in terms of architecture too, is moving touch handling into the Cell, like this:
class TableViewCellrow: UITableViewCell {
var btnCrossTapHandler: (() -> Void)?
#IBOutlet weak var btnCross: UIButton!
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
initialize()
}
required init?(coder: NSCoder) {
super.init(coder: coder)
initialize()
}
private func initialize() {
btnCross.addTarget(self, action: #selector(cutt), for: .touchUpInside)
}
#objc func cutt() {
btnCrossTapHandler?()
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
...
cell.btnCrossTapHandler = { [weak self] in
// you have indexPath here
}
...
}

Don't use tuples in a datasource array. This is very bad practice.
Create a custom struct like
struct Section {
let title : String
let items : [String]
}
let namearr = [Section(title: "Vegtable", items: ["cauliflower","radish"]),
Section(title: "Fruit", items: ["grapres","mango"]),
Section(title: "FLower", items: ["lily","marigold"])]
The capitalized names can be simply created with
let section = namearr[indexPath.section]
let name = section.items[indexPath.row]
let capName = name.capitalized
For the tag I recommend a calculation section * 100 + row
func tag(for indexPath : IndexPath) -> Int {
return indexPath.section * 100 + indexPath.row
}
and the other way round
func indexPath(for tag : Int) -> IndexPath {
return IndexPath(row: tag % 100, section: tag / 100)
}
