iPhone键盘布局为负数？ [英] iPhone keyboard layout for negative numbers?

问题描述

我的用户需要输入纬度和经度，当然我需要验证输入的值是否是合法的纬度/经度值。我想要一个键盘布局，为我做一些（消除字母字符，标点符号等，只留下数字和+/-）。数字键盘键盘似乎没有这样做（缺少+/-），也没有随SDK附带的任何其他键盘布局。有没有人知道是否有办法提供这种能力而不用我自己的键盘IME和越狱手机？

My users need to enter latitude and longitude, and of course I need to verify that the values entered are legitimate lat/long value. I'd like to have a keyboard layout that does some of this for me (eliminating alphabetic characters, punctuation, etc, and leaving only the numbers and +/-). The number pad keyboard doesn't seem to do it (missing +/-) and neither do any other keyboard layouts that come with the SDK. Does anyone know if there is a way to provide that capability without doing my own keyboard IME and jailbreaking the phone?

谢谢！
