I am unable to access constant or variables which are defined inside a function for example i have defined a constant inside a didselectrow
function now when i select a row the value of constant get printed in console but now i want to save that value in firebase
so when i call that value in button
it is undefined why? what should i do that??
here is the code i have written in button
the constant countryGroup
is undefined. because i have defined it in didselectrow
button
@IBAction func createAccountAction(_ sender: Any) {
ref.child("user_registration").child(UserID!).setValue(["username": fullName.text, "email": emailTextField.text, "contact": numberText.text, "city": myCity.text, "state": countryText.text, "country": country])
}
didselectrow
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if tableView == tableViewB {
let selectedData = dropDownList[indexPath.row]
buttonB.setTitle(selectedData, for: .normal)
self.tableViewB.isHidden = true
self.flag = 1
let indexPath = tableViewB.indexPathForSelectedRow
let currentCell = tableViewB.cellForRow(at: indexPath!)! as UITableViewCell
let country = currentCell.textLabel!.text!
print("\(country)")
}
Instead of defining let country = currentCell.textLabel!.text!
in didselectrow
i have defined a global variable var country = String?
and set country = currentCell.textLabel!.text!
