title: How to have the iOS SearchBar Keyboard Search Button Perform an Action
body: <p>I have a simple application which has a Table View (TV1) which gets populated by the user selecting a navigation bar button item to Add Entry (VC1). Within the Add Entry, when the user presses the Name field, they're taken to another Table View (TV2) which serves the purpose of allowing the user to select a previously entered name or create a new name. </p>
  
  <p>TV2 is a Table View Controller with a Search Bar at the top. </p>
  
  <p>Right now, existing names are available and show to the user. However, if the user "searches" for a name that does not exist, they should have the option to Create that name right now. If a search does not exist, I have a button which the user can tap which will create the user. That's simple. However, it's another tap. </p>
  
  <p>Is there a way I can get the Search button of the Keyboard to perform the same functionality of the create button (i.e. Save the new user and dismiss TV1) which would then allow me to remove the Create button in the middle of the table view?</p>
