Swift - 键盘弹出样式
Swift提供了11种键盘类型:
在开发中,我们可以根据不同的需求,选择不同的键盘样式,例如,当我们只需要输入手机号码时,可以选择纯数字类型的键盘(.NumbersAndPunctuation),当我们需要输入网址时,可以选择URL样式的键盘(.URL),其中,默认的键盘样式(.Default)就是(.NamePhonePad)样式。
我们可以通过输入框的 UIKeyboardType 来设置键盘样式
UITextField().keyboardType = .NamePhonePad
//
// UIKeyboardType
//
// Requests that a particular keyboard type be displayed when a text widget
// becomes first responder.
// Note: Some keyboard/input methods types may not support every variant.
// In such cases, the input method will make a best effort to find a close
// match to the requested type (e.g. displaying UIKeyboardTypeNumbersAndPunctuation
// type if UIKeyboardTypeNumberPad is not supported).
//
public enum UIKeyboardType : Int {
case Default // Default type for the current input method.
case ASCIICapable // Displays a keyboard which can enter ASCII characters, non-ASCII keyboards remain active
case NumbersAndPunctuation // Numbers and assorted punctuation.
case URL // A type optimized for URL entry (shows . / .com prominently).
case NumberPad // A number pad (0-9). Suitable for PIN entry.
case PhonePad // A phone pad (1-9, *, 0, #, with letters under the numbers).
case NamePhonePad // A type optimized for entering a person‘s name or phone number.
case EmailAddress // A type optimized for multiple email address entry (shows space @ . prominently).
@available(iOS 4.1, *)
case DecimalPad // A number pad with a decimal point.
@available(iOS 5.0, *)
case Twitter // A type optimized for twitter text entry (easy access to @ #)
@available(iOS 7.0, *)
case WebSearch // A default keyboard type with URL-oriented addition (shows space . prominently).
public static var Alphabet: UIKeyboardType { get } // Deprecated
}
