I get the error after I open UIPickerView.
My UIPickerView has 16 gadgets.
func open_activity_picker()
{
activity_UIPickerView = UIPickerView()
activity_UIPickerView.delegate = self
activity_UIPickerView.dataSource = self
activity_UIPickerView.backgroundColor = UIColor.white
activity_UIPickerView.setValue(UIColor.black, forKey: "textColor")
activity_UIPickerView.autoresizingMask = .flexibleWidth
activity_UIPickerView.contentMode = .middle
activity_UIPickerView.body = CGRect.init( x: 0.0,
y: 10, //UIScreen.most important.bounds.dimension.top - 300,
width: UIScreen.most important.bounds.dimension.width,
top: 300)
self.view.addSubview(activity_UIPickerView)
}
func numberOfComponents(in pickerView: UIPickerView) -> Int
{
return 1 // complete picker columns
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent element: Int) -> Int
{
return 16
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent element: Int) -> String?
{
var activity_title = ""
var nmbr_activity_title = ""
change( row )
{
case 0: activity_title = "aerobics "; nmbr_activity_title = " 1. aerobics "

}
activity_title = TRIM( activity_title )
activity_title = activity_title.replacingOccurrences(of: " ", with: "_", choices: .literal, vary: nil)
activity_selection_types[ row ] = activity_title
// Choose boot default if no exercise chosen?
if activity_selection_type == "" && row == 0
{
activity_selection_type = activity_title
}
// row is earlier person choice of activity_selection_type?
if activity_title == activity_selection_type
{
activity_UIPickerView.selectRow( row, inComponent: element, animated: true)
}
return( TRIM( nmbr_activity_title ))
}
