title: Set default tint color for all UIButtons in an app
body: <p>My iPad app I has a number of UIButtons that when pressed turn blue by default. I could go through each one and set the tintcolor using:</p>
  
  <pre><code>[buttonName setTintColor:[UIColor colorWithRed:151/255.0f green:202/255.0f blue:86/255.0f alpha:1.0]];
  </code></pre>
  
  <p>But is there anyway of changing this colour by default and for all buttons?</p>
