title: ios change button title font when pressed
body: <p>i'm new on ios and i wonder if is it possible to change button's title font when it is pressed, i can change button's color when its highlighted as:</p>
  
  <pre><code>[button setTitleColor:[UIColor colorWithRed:255/255.0 green:255/255.0 blue:255/255.0 alpha:1.0] forState:UIControlStateHighlighted];
  </code></pre>
  
  <p>is there anything like this to change button's font size, without writing button pressed methods.(i want to change font on highlighted state, so i'm not sure if buttonPressed method will work clearly)</p>
