Ok so Im creating a UIPickerView programmatically to trigger from a UITextField inside a TableCell(this may be a stupid idea but lets go with it for now anyway).
I refactored all the code for it into its own class to declutter my UIViewControler:
class SeveritySection {
let pickerToolbar: UIToolbar!
let picker: UIPickerView!
let textField: UITextField!
let tableCell: UITableViewCell!
var pickerOptions = Array<String>()
init() {
pickerToolbar = UIToolbar()
picker = UIPickerView()
tableCell = UITableViewCell()
textField = UITextField(frame: CGRectInset(tableCell.contentView.bounds, 15, 0))
}
func setOptions(optionsArray:Array<String>){
pickerOptions = optionsArray;
}
/// Initalises the toolbar with done on the rhs for picker
/// :param: colour of the toolbar
func createPickerToolbarwith(#colour:UIColor){
let flexSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
let doneButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Done, target: nil,action: Selector("doneButtonAction"))
let toolbarButtons = [flexSpace, doneButton];
pickerToolbar.sizeToFit()
pickerToolbar.setItems(toolbarButtons, animated: true)
pickerToolbar.backgroundColor = colour
}
func setupTextfield(){
textField.placeholder = "Choose Severity"
textField.inputView = picker
textField.inputAccessoryView = pickerToolbar
// self.severityText.keyboardType = UIKeyboardType.NumberPad
tableCell.addSubview(textField)
}
func setPickerDelegate(viewController: SinnerFormViewController){
picker.delegate = viewController
picker.dataSource = viewController
}
func setTextFieldTo(text:String){
self.textField.text = text
}
func doneButtonAction() {
textField.resignFirstResponder()
println("Done pressed")
}
And so then I call in my UIViewController
var severitySection = SeveritySection()
self.severitySection.setPickerDelegate(self)
self.severitySection.createPickerToolbarwith(colour: UIColor.whiteColor())
self.severitySection.pickerToolbar.delegate = self
self.severitySection.setupTextfield()
but pressing the done button in the spinner toolbar won't fire any events. I tried setting the viewcontroller as the delegate to the UIToolbar, but that didnt change anything. I believe what I did was just refactor inline code in my view controller but I guess I missed something, or something implicitly defined is no longer there
