当用户点击UIExtField时，我很难创建一个带有"完成"按钮的UIPickerView.这是我目前的代码.一切都很好，但当我点击文本字段时，会出现键盘，而不是 Select 器.
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()
}
}
