title: How to determine which button was pressed out of three buttons
body: <p>I have three buttons, they all do the same thing perform a segue. All linked to the same connection.</p>
  
  <pre><code>- (IBAction)difficultyButtonPressed:(id)sender {
      // Any difficulty selected
      [self performSegueWithIdentifier:@"mainGameTurnGuess" sender:self];
  }
  </code></pre>
  
  <p>What I need to do is determine what button was pressed in the <code>prepareForSegue</code> method. How can I tell which out of the three buttons are pressed.</p>
  
  <p>Without looking at the wording/text on the button as this would change for localisation. </p>
