Как сделать UIPickerView с кнопкой Готово?
У меня возникли трудности с созданием UIPickerView с кнопкой «Готово», которое будет отображаться, когда пользователи нажимают на UITextField. Это мой код до сих пор. Все строит нормально, но когда я нажимаю на текстовое поле, появляется клавиатура, а не сборщик.
class ViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {
@IBOutlet var textField1: UITextField!
let pickerData = ["11", "12", "13"]
@IBAction func textButton(sender: AnyObject) {
let picker: UIPickerView
picker = UIPickerView(frame: CGRectMake(0, 200, view.frame.width, 300))
picker.backgroundColor = .whiteColor()
picker.showsSelectionIndicator = true
picker.delegate = self
picker.dataSource = self
let toolBar = UIToolbar()
toolBar.barStyle = UIBarStyle.Default
toolBar.translucent = true
toolBar.tintColor = UIColor(red: 76/255, green: 217/255, blue: 100/255, alpha: 1)
toolBar.sizeToFit()
let doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Plain, target: self, action: "donePicker")
let spaceButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
let cancelButton = UIBarButtonItem(title: "Cancel", style: UIBarButtonItemStyle.Plain, target: self, action: "donePicker")
toolBar.setItems([cancelButton, spaceButton, doneButton], animated: false)
toolBar.userInteractionEnabled = true
textField1.inputView = picker
textField1.inputAccessoryView = toolBar
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return pickerData.count
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return pickerData[row]
}
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
textField1.text = pickerData[row]
}
func donePicker() {
textField1.resignFirstResponder()
}
}
