title: iPhone: Custom keyboard layout and theme
body: <p>I am wondering if anyone knows how to or can like me to some documentation or tutorials on how to make custom iOS keyboard sets as well as theming the iOS keyboard. I have read everything I could find, watched many youtube videos and read related posts on here. Most are just making a keyboard from scratch with a bunch of buttons or just tell you how to use the other iOS layouts like email, keypad etc. I need to create a custom keypad set. It must be able to be done, the Wolfram|Alpha Calculus apps have custom keyboard layouts and modified themes. If anyone has any info, please send it my way!</p>
