UITextField 키보드에 아래와 같은 UIToolbar를 구현하고 싶습니다. 안이하게 실장이 되어 매우 편리하다고 생각했으므로 써 남겨 둡니다.

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var addressField: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
        addToolBar(textField: addressField)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

extension UIViewController: UITextFieldDelegate{
    func addToolBar(textField: UITextField){
        let toolBar = UIToolbar()
        toolBar.barStyle = UIBarStyle.default
        toolBar.isTranslucent = true
        toolBar.tintColor = UIColor(red: 76/255, green: 217/255, blue: 100/255, alpha: 1)
        let doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.done, target: self, action: #selector(UIViewController.donePressed))
        let cancelButton = UIBarButtonItem(title: "Cancel", style: UIBarButtonItemStyle.plain, target: self, action: #selector(UIViewController.cancelPressed))
        let spaceButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.flexibleSpace, target: nil, action: nil)
        toolBar.setItems([cancelButton, spaceButton, doneButton], animated: false)
        toolBar.isUserInteractionEnabled = true
        toolBar.sizeToFit()

        textField.delegate = self
        textField.inputAccessoryView = toolBar
    }
    func donePressed(){
        view.endEditing(true)
    }
    func cancelPressed(){
        view.endEditing(true) // or do something
    }
}

구현

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var addressField: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
        addToolBar(textField: addressField)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

extension UIViewController: UITextFieldDelegate{

    func addToolBar(textField: UITextField){
        let toolBar = UIToolbar()
        toolBar.barStyle = UIBarStyle.default
        toolBar.isTranslucent = true
        toolBar.tintColor = UIColor(red: 76/255, green: 217/255, blue: 100/255, alpha: 1)

        let JayZButton = UIBarButtonItem(title: "JayZ", style: UIBarButtonItemStyle.done, target: self, action: #selector(UIViewController.RapGod))

        let BeyoncéButton = UIBarButtonItem(title: "Beyoncé", style: UIBarButtonItemStyle.plain, target: self, action: #selector(UIViewController.JayZwife))

        let DrakeButton = UIBarButtonItem(title: "Drake", style: UIBarButtonItemStyle.plain, target: self, action: #selector(UIViewController.bestIeverHad))

        let RihannaButton = UIBarButtonItem(title: "Rihanna", style: UIBarButtonItemStyle.plain, target: self, action: #selector(UIViewController.DrakeLoveRihanna))

        //let spaceButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.flexibleSpace, target: nil, action: nil)

        toolBar.setItems([JayZButton, BeyoncéButton, DrakeButton, RihannaButton], animated: false)
        toolBar.isUserInteractionEnabled = true
        toolBar.sizeToFit()

        textField.delegate = self
        textField.inputAccessoryView = toolBar
    }

    func RapGod(){
//        view.endEditing(true)
        print("ラップの神様")
    }

    func JayZwife(){
//        view.endEditing(true)
        print("JayZの嫁")
    }

    func bestIeverHad(){
        print("bestIeverHad")
    }

    func DrakeLoveRihanna(){
        print("ドレイクはリアーナが大好き")
    }
}
