title: How to make the keyboard go away in the iphone simulator
body: <p>I've got one text entry box in my iphone app, when you touch it in the simulator, the keyboard pops up. But there's no way to get rid of it.
  Other web pages give solutions, without explaining why they should work, and they don't work for me.
  One says make the text box's delegate your uiview then call resignfirstresponder on the object, but it never gets called.
  Any suggestions? Can anybody explain what's actually going on? I can figure it out myself if I knew what the design paradigm was...</p>
  
  <p>Maybe I should just put a "go" button so I have something to get the focus away from the textfield?</p>
