title: CoreData Edit/Overwrite Object
body: <p>I am playing around with a new project, a split view iPad app using <strong>Core Data</strong>, and I was wondering, as its fairly clear how to add and remove an item. If I was to say alter this to hold text, then that text be shown in a <code>UITextView</code>, how can I edit or overwrite an object in <strong>CoreData</strong>?</p>
  
  <p>So the user types their note in the <code>UITextView</code> and when they leave that it edits and saves the note (object in the table view) they have currently selected.</p>
  
  <p>Appreciate any help thanks.</p>
