简介

键盘类型的书写风格和类型我想在这里总结一下。

定义

我通过跳转到定义检查了UIKeyboardType的定义(按住Command键并单击要检查的位置)。

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, ?-?, ?-?, 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
}

实现方法

将

TextField连接到outlets，并使用viewDidLoad编写显示代码。
让我们更改以下内容以查看每种键盘类型。
