キーボードタイプの種類とコード #初心者

はじめに

キーボードタイプの書き方や種類一旦ここにまとめようかなと思います。

定義

UIKeyboardTypeの定義をJump to Definition（コマンドキーを押しながら調べたいところをクリック）で調べてみました。
以下の通りです。

public enum UIKeyboardType : Int {


    case `default` = 0 // Default type for the current input method.

    case asciiCapable = 1 // Displays a keyboard which can enter ASCII characters

    case numbersAndPunctuation = 2 // Numbers and assorted punctuation.

    case URL = 3 // A type optimized for URL entry (shows . / .com prominently).

    case numberPad = 4 // A number pad with locale-appropriate digits (0-9, ۰-۹, ०-९, etc.). Suitable for PIN entry.

    case phonePad = 5 // A phone pad (1-9, *, 0, #, with letters under the numbers).

    case namePhonePad = 6 // A type optimized for entering a person's name or phone number.

    case emailAddress = 7 // A type optimized for multiple email address entry (shows space @ . prominently).

    @available(iOS 4.1, *)
    case decimalPad = 8 // A number pad with a decimal point.

    @available(iOS 5.0, *)
    case twitter = 9 // A type optimized for twitter text entry (easy access to @ #)

    @available(iOS 7.0, *)
    case webSearch = 10 // A default keyboard type with URL-oriented addition (shows space . prominently).

    @available(iOS 10.0, *)
    case asciiCapableNumberPad = 11 // A number pad (0-9) that will always be ASCII digits.


    public static var alphabet: UIKeyboardType { get } // Deprecated
}

実装方法

TextFieldをアウトレットで接続して、viewDidLoadで表示のコードを書きます。
.以降を変更してそれぞれのキーボードタイプを見ていきます。

import UIKit

class ViewController: UIViewController {

    @IBOutlet var textField1: UITextField!
    @IBOutlet var textField2: UITextField!
    @IBOutlet var textField3: UITextField!
    @IBOutlet var textField4: UITextField!
    @IBOutlet var textField5: UITextField!
    @IBOutlet var textField6: UITextField!
    @IBOutlet var textField7: UITextField!
    @IBOutlet var textField8: UITextField!
    @IBOutlet var textField9: UITextField!
    @IBOutlet var textField10: UITextField!
    @IBOutlet var textField11: UITextField!
    @IBOutlet var textField12: UITextField!
    @IBOutlet var textField13: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        self.textField1.keyboardType = .default
        self.textField2.keyboardType = .asciiCapable
        self.textField3.keyboardType = .numbersAndPunctuation
        self.textField4.keyboardType = .URL
        self.textField5.keyboardType = .numberPad
        self.textField6.keyboardType = .phonePad
        self.textField7.keyboardType = .namePhonePad
        self.textField8.keyboardType = .emailAddress
        self.textField9.keyboardType = .decimalPad
        self.textField10.keyboardType = .twitter
        self.textField11.keyboardType = .webSearch
        self.textField12.keyboardType = .asciiCapableNumberPad
        self.textField13.keyboardType = .alphabet
    }
}
