I'm Trying to Create a Demo, On Register Page I have 3 TextField, From date and To Date and Date of Birth. I want to use Date Picker and Time Picker for all the textfield. I gave delegate and created a action as well, but it is Not working. How can I do this. Can someone guide me.
here is my code
txtCopy.delegate = self
txtConvert.delegate = self
txtToCopy.delegate = self
self.txtCopy.datePicker(target: self,
doneAction: #selector(doneAction(_:)),
cancelAction: #selector(cancelAction(_:)),
datePickerMode: .date)
self.txtConvert.datePicker(target: self,
doneAction: #selector(doneAction(_:)),
cancelAction: #selector(cancelAction(_:)),
datePickerMode: .date)
self.txtToCopy.datePicker(target: self,
doneAction: #selector(doneAction(_:)),
cancelAction: #selector(cancelAction(_:)),
datePickerMode: .date)
objc
func cancelAction(_ textField: UITextField) {
self.txtConvert.resignFirstResponder()
}
@objc
func doneAction(_ textField: UITextField) {
if let datePickerView = txtCopy!.inputView as? UIDatePicker {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd-MM-yyyy"
let dateString = dateFormatter.string(from: datePickerView.date)
if self.selectedTextField!.tag == 0 {
self.txtConvert.text = dateString
print(datePickerView.date)
print(dateString)
self.txtConvert.resignFirstResponder()
}
else if self.selectedTextField!.tag == 1 {
self.txtCopy.text = dateString
print(datePickerView.date)
print(dateString)
self.txtCopy.resignFirstResponder()
} else if self.selectedTextField!.tag == 2 {
self.txtToCopy.text = dateString
print(datePickerView.date)
print(dateString)
self.txtToCopy.resignFirstResponder()
}
}
}

I have Created a demo On This earlier Let me show you.
Add this Extension to your Class.
**Extension For TextField **
extension UITextField {
func datePicker<T>(target: T,
doneAction: Selector,
cancelAction: Selector,
datePickerMode: UIDatePicker.Mode = .date) {
let screenWidth = UIScreen.main.bounds.width
func buttonItem(withSystemItemStyle style: UIBarButtonItem.SystemItem) -> UIBarButtonItem {
let buttonTarget = style == .flexibleSpace ? nil : target
let action: Selector? = {
switch style {
case .cancel:
return cancelAction
case .done:
return doneAction
default:
return nil
}
}()
let barButtonItem = UIBarButtonItem(barButtonSystemItem: style,
target: buttonTarget,
action: action)
return barButtonItem
}
let datePicker = UIDatePicker(frame: CGRect(x: 0,
y: 0,
width: screenWidth,
height: 216))
datePicker.datePickerMode = datePickerMode
datePicker.preferredDatePickerStyle = .inline
self.inputView = datePicker
let toolBar = UIToolbar(frame: CGRect(x: 0,
y: 0,
width: screenWidth,
height: 44))
toolBar.setItems([buttonItem(withSystemItemStyle: .cancel),
buttonItem(withSystemItemStyle: .flexibleSpace),
buttonItem(withSystemItemStyle: .done)],
animated: true)
self.inputAccessoryView = toolBar
}
}
How To use
create variable
var selectedTextField: UITextField?
In Your View DidLoad method
txtCopy.delegate = self
txtConvert.delegate = self
txtToCopy.delegate = self
self.txtCopy.datePicker(target: self,
doneAction: #selector(doneAction(_:)),
cancelAction: #selector(cancelAction(_:)),
datePickerMode: .date)
self.txtConvert.datePicker(target: self,
doneAction: #selector(doneAction(_:)),
cancelAction: #selector(cancelAction(_:)),
datePickerMode: .date)
self.txtToCopy.datePicker(target: self,
doneAction: #selector(doneAction(_:)),
cancelAction: #selector(cancelAction(_:)),
datePickerMode: .date)
**Call @objc methods **
@objc
func cancelAction(_ textField: UITextField) {
self.txtConvert.resignFirstResponder()
}
@objc
func doneAction(_ textField: UITextField) {
if let datePickerView = selectedTextField!.inputView as? UIDatePicker {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd-MM-yyyy"
let dateString = dateFormatter.string(from: datePickerView.date)
if self.selectedTextField!.tag == 0 {
self.txtConvert.text = dateString
print(datePickerView.date)
print(dateString)
self.txtConvert.resignFirstResponder()
}
else if self.selectedTextField!.tag == 1 {
self.txtCopy.text = dateString
print(datePickerView.date)
print(dateString)
self.txtCopy.resignFirstResponder()
} else if self.selectedTextField!.tag == 2 {
self.txtToCopy.text = dateString
print(datePickerView.date)
print(dateString)
self.txtToCopy.resignFirstResponder()
}
}
}
I Hope it will Help.
