How to build a tableview that takes keyboard input and displays an autocomplete list

This is a companion demo to the blog post: http://eskimona.com/objective-c/2015/03/28/autocomplete-tableview.html and demonstrates that reloadData will ask the cells and their UIResponders to resign first responder.

If you subclass the related responder (in this case a UITextField) to override resignFirstResponder, the necessary tableview under the hood methods will not get called and reloadData will not behave as expected.

There are three stages to this demo project.

Initial: -[UITableView reloadData] called, -[UITextField resignFirstResponder] called by system

Expected behavior: user types a character into the textfield, related alphabetimal cells are loaded but the keyboard will be dismissed without updating the character in the textfield

Click to Type: the UITextField is overriden to return YES instead of calling

resignFirstResponder.

Expected behavior: user types as many characters as she like, the cells will not be updated from whatever their previous state was.

Click on Solution: UITableView no longer contains UITextField in one of its cells

Expected behavior: user types characters; the textfield will be updated with those characters and the tableview will be updated with appropriate alphabetimals that match that string
