Update UITableViewCell - ios

Question

I've got a problem. I have this tableview and this pickerView
and this is the pickerView functions of the viewcontroller:
let gender = ["M","F"]
#IBOutlet weak var dataTableView: UITableView!
//pickerFuncs
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return gender[row]
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return gender.count
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
print(gender[row])
}
How to modify the "m" in the cell with the selection of the uipicker? thanks everybody!

Answer 1

Create a variable
var currentGender = "M"
Set your TableViewCell with currentGender like
cell.gender = currentGender
When you select a row in UIPickerView,
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
currentGender = gender[row]
// Then reload your TableView row
let indexPath = IndexPath(item: rowNumber, section: 0)
tableView.reloadRows(at: [indexPath], with: .top)
}

Answer 2

I'm assuming you want to have your M and F appear inside your pickerView. To do this you have to create a reference. This can be done through an IBOutlet or you can do it programmatically like so: let pickerView = UIPickerView(). On a side note, I am also assuming you are only using one pickerView in the View Controller. If you are using multiple, set each of the pickerViews a tag. This can be done in the interface builder and programatically like so: pickerView.tag = 1. Then change your pickerView functions based on those tags.

Answer 3

Create a variable.
var gender = "M"
Initialise again your gender variable. In this delegate method.
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
gender = gender[row]
// Then reload your TableView row
table view.reloadData()
}
Add these lines to your cellforrow_atIndexPath.
Cell.genderIdicatorLbl.text = gender
Note: genderIndicatorLbl is IBOutlet for your gender indicator Label
