UIDatePickerView Demo

Note : When user click on UITextfield, UIDatePicker is open.

step 1: Put UITextfield and give their IBOutlet and textfielddelegate.
step 2 : In ViewController, create variable of UIDatepicker. Like,

var date_1 = UIDatePicker()

step 3: Create function with argument. Like,

func pick_Date(_ textfield : UITextField) {

        //For create date picker...

        self.date_1 = UIDatePicker(frame: CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: 215))

        self.date_1.backgroundColor = UIColor.white

        lf.date_1.datePickerMode = .date

        self.txt_select_date.inputView = date_1

        

        //for create toolbar...

        let toolbar = UIToolbar()

        toolbar.barStyle = .default

        toolbar.isTranslucent = true

        toolbar.tintColor = UIColor(red: 90/255, green: 215/255, blue: 255/255, alpha: 1)

        toolbar.sizeToFit()

        

        //Add button toolbar...

        let btn_add = UIBarButtonItem(title: "Done", style: .plain, target: self, action: #selector(Date_ViewController.click_Done))

        let btn_space = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)

        let btn_cancel = UIBarButtonItem(title: "Cancel", style: .plain, target: self, action: #selector(Date_ViewController.click_Cancel))

        toolbar.setItems([btn_add, btn_space, btn_cancel], animated: true)

        toolbar.isUserInteractionEnabled = true

        txt_select_date.inputAccessoryView = toolbar

    }

step 4: Create done button and cancel button item function. Like,

func click_Done() {

        let date_Formatter = DateFormatter()

        date_Formatter.dateStyle = .medium

        date_Formatter.timeStyle = .none

        txt_select_date.text = date_Formatter.string(from: date_1.date)

        txt_select_date.resignFirstResponder()

    }

    

    func click_Cancel() {

        txt_select_date.resignFirstResponder()

    }

step 5: Call "pic_date" function on textfieldDidBeginEditing delegate method. Like,

func textFieldDidBeginEditing(_ textField: UITextField) {

        self.pick_Date(self.txt_select_date)

    }

Thank you...
