Show Array of String in Picker View?

Question

How to show array of strings in picker view without using didSelect delegate method ?

Answer 1

func numberOfComponents(in pickerView: UIPickerView) -> Int
{
    return 1 // the amount of "columns" in the picker view
}

func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int
{
    return yourArray.count // the amount of elements (row)
}

func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String?
{
    return yourArray[row] // the actual string to display for the row "row"
}

Simple as that. No didSelect needed. The didSelect delegate function is called whenever you change your selection in the picker view. You don't need that one for displaying data
