How to Load data into textfield when pickerview is launched - ios

Question

I created a custom pickerview as a keyboard with a done button and everything, but I'm having a bit of trouble figuring out how to load the data immediately from the start, I did it in my datepicker, but now I'm trying to figure out how to do it in a normal picker keyboard that I custom made.
Here is my code:
import UIKit
import CoreData
class ViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource, NSFetchedResultsControllerDelegate {
#IBOutlet weak var stateText: UITextField!
#IBOutlet weak var taxNumb: UITextField!
#IBOutlet weak var output: UILabel!
func doneButton() {
let doneToolbar : UIToolbar = UIToolbar(frame: CGRectMake(0, 0, 320, 50))
doneToolbar.barStyle = UIBarStyle.Default
let flexSpace = UIBarButtonItem(barButtonSystemItem: .FlexibleSpace, target: nil, action: nil)
let done : UIBarButtonItem = UIBarButtonItem(title: "Done", style: .Done, target: self, action: ("doneButtonAction"))
var items = [UIBarButtonItem]()
items.append(flexSpace)
items.append(done)
doneToolbar.items = items
doneToolbar.sizeToFit()
self.stateText.inputAccessoryView = doneToolbar
self.taxNumb.inputAccessoryView = doneToolbar
}
func doneButtonAction() {
self.stateText.resignFirstResponder()
self.taxNumb.resignFirstResponder()
}
let moc = (UIApplication.sharedApplication().delegate as! AppDelegate).managedObjectContext
let tax : Tax? = nil
var stateArray = [
"AK - Alaska",
"AL - Alabama",
"AR - Arkansas",
"AZ - Arizona",
"CA - California",
]
func statePickerKey() {
let statePickerView = UIPickerView()
statePickerView.dataSource = self
statePickerView.delegate = self
stateText.inputView = statePickerView
}
override func viewDidLoad() {
super.viewDidLoad()
statePickerKey()
doneButton()
}
override func viewDidAppear(animated: Bool) {
statePickerKey()
}
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return stateArray.count
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return stateArray[row]
}
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
return stateText.text = stateArray[row] as String
}
#IBAction func printTapped(sender: AnyObject) {
let entityDescription = NSEntityDescription.entityForName("Tax", inManagedObjectContext: moc)
let taxes = Tax(entity: entityDescription!, insertIntoManagedObjectContext: moc)
taxes.state = stateText.text
if stateText.text == "AK - Alaska" {
taxes.alaska = Double(taxNumb.text!)
output.text = taxes.alaska?.stringValue
} else if stateText.text == "AL - Alabama" {
taxes.alabama = Double(taxNumb.text!)
self.output.text = taxes.alabama?.stringValue
} else if stateText.text == "AR - Arkansas" {
taxes.arkansas = Double(taxNumb.text!)
output.text = taxes.arkansas?.stringValue
} else if stateText.text == "AZ - Arizona" {
taxes.arizona = Double(taxNumb.text!)
output.text = taxes.arizona?.stringValue
} else if stateText.text == "CA - California" {
taxes.california = Double(taxNumb.text!)
output.text = taxes.california?.stringValue
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

Answer 1

you create datepicker, after that set textfield.text = datePickerView.date
