title: How to make ios keyboard appear manually?
body: <p>I have a custom view which will act as a text field and another custom view hat acts as its keyboard. I was planning on implementing uikeyinput protocol, but since its a custom keyboard, it can't send messages to its delegate through uikeyinput, so I thought I might as well make a custom protocol as well. 
  After making the text field first responder, how do I program the keyboard to appear when someone clicks the text field?</p>
