I'm trying to get my picker to reload the data from Firebase. It responds to the first thing in the textLbl when viewed. I would like it to reload using one of the other strings as well. example I T is the first line to appear its already set there. I would like it to change when I move the selector an choose say safety.
let officePerson = ["I T","SAFETY","H R/PAYROLL/BENEFITS DEPT","QUALITY","BUSINESS DEVELOPMENT SUPPORT","ACCOUNTING","RECRUITING","MAINTENANCE","SPECIAL PROJECTS","DISPATCH"]
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return officePerson[row]
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return officePerson.count
}
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
pickerLbl.text = officePerson[row]
self.view.endEditing(false)
picker.reloadAllComponents()
}
