title: iPhone UITextField - Change placeholder text color
body: <p>I'd like to change the color of the placeholder text I set in my <code>UITextField</code> controls, to make it black.</p>
  
  <p>I'd prefer to do this without using normal text as the placeholder and having to override all the methods to imitate the behaviour of a placeholder.</p>
  
  <p>I believe if I override this method:</p>
  
  <pre><code>- (void)drawPlaceholderInRect:(CGRect)rect
  </code></pre>
  
  <p>then I should be able to do this. But I'm unsure how to access the actual placeholder object from within this method.</p>
