I am adding cancel and done button on top of UIpickerView in my ios app, but I am getting error like- [Avakaash.Profile_add_update donePicker]: unrecognized selector sent to instance 0x7faf19daf1f0' and my code looks like below-
override func viewDidLoad() {
super.viewDidLoad()
std_class_pickerView.tag = 0
country_pickerview.tag = 1
std_class_pickerView = UIPickerView(frame: CGRectMake(0, 200, view.frame.width, 300))
std_class_pickerView.backgroundColor = .whiteColor()
std_class_pickerView.showsSelectionIndicator = true
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.Bordered, target: self, action: Selector("donePicker"))
let spaceButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
let cancelButton = UIBarButtonItem(title: "Cancel", style: UIBarButtonItemStyle.Bordered, target: self, action: Selector("canclePicker"))
toolBar.setItems([cancelButton, spaceButton, doneButton], animated: false)
toolBar.userInteractionEnabled = true
std_class_pickerView.delegate = self
text_std_class.inputView = std_class_pickerView
text_std_class.inputAccessoryView = toolBar
}
and my controller class look like-
class Profile_add_update: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {
}
error log-
[Avakaash.Profile_add_update donePicker]: unrecognized selector sent to instance 0x7faf19daf1f0

you forget to implement the action of donePicker
and canclePicker
button do like
func donePicker () //Create an IBAction
{
// do something
}
func canclePicker () //Create an IBAction
{
// do something
}
full code
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:.Plain, target: self, action: #selector(ViewController.donePicker))
let spaceButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
let cancelButton = UIBarButtonItem(title: "Cancel", style:.Plain, target: self, action: #selector(ViewController.canclePicker))
toolBar.setItems([cancelButton, spaceButton, doneButton], animated: false)
toolBar.userInteractionEnabled = true
action like
func donePicker () //Create an IBAction
{
// do something
}
func canclePicker () //Create an IBAction
{
// do something
}
