iOs имеет цифровую клавиатуру UIKeyboardTypeNumbersAndPunctuation, но это нельзя вызвать из HTML (https://developer.apple.com/library/ios/documentation/StringsTextFonts/Conceptual/TextAndWebiPhoneOS/KeyboardManagement/KeyboardManagement.html)
, поскольку на клавиатуре "tel" пунктуация отсутствует, вы должны создать ее самостоятельно. Начиная с ios8 доступны пользовательские клавиатуры. Или, если вам нужна пунктуация, вы можете добавить кнопку ( Как добавить кнопку «Готово» на клавиатуре numpad в iOS ) к цифровой клавиатуре, которая появляется, когда вы задаете поле ввода с помощью type="number" pattern="[0-9]*" .
Для этого: код объектива-c.

Затем вы должны добавить метод, который может быть доступен для всего приложения, в вашем коде JS.
simulateKeyPress: function(k) {
var press = jQuery.Event("keypress");
press.which = k;
// place the id of your most outer html tag here
$("#body").trigger(press);
// just needed because my active element has a child element where the value should be placed in
var id = document.activeElement.id.indexOf("-");
if(id != -1){
var currentTf = sap.ui.getCore().byId(document.activeElement.id.split("-")[0]);
//append the value and set it (my textfield has a method setValue())
var currentTfValue = currentTf.getValue();
currentTf.setValue(currentTfValue + k);
}
