title: Replacing UITextField input with a UIDatePicker
body: <p>I have a table view controller with (among others) a cell that is to represent a date.  I followed this post "<a href="https://stackoverflow.com/questions/8484147/how-do-i-make-a-modal-date-picker-that-only-covers-half-the-screen">How do I make a modal date picker that only covers half the screen?</a>" and I have it working with one big exception - I can't get the picker to disappear!</p>
  
  <p>I tried registering for the event UIControlEventTouchUpOutside, but it seems that this is not generated by the picker (or at least in the mode that I am using it).</p>
  
  <p>How can I recognize that the user has finished selecting a date?</p>
  
  <p>Also, is there a way to disable the user from inputting directly into the UITextField?  I want to force them to use the picker.  I saw this post "<a href="https://stackoverflow.com/questions/11065946/replacing-uitextfield-input-with-a-uidatepicker">Disable blinking cursor in UITextField?</a>",  but is there another way?</p>
  
  <p>Reagards,</p>
