title: iOS Foundation: system font size
body: <p>I would like to know if systemFontSize in iOS app tableView is <strong>always</strong> the same for textLabel? This is are depening to style?</p>
  
  <p>For example when I  <code>NSLog(@"%f",[UIFont systemFontSize]);</code> I'm getting 14.0. Is this are always the same?</p>
  
  <p>And what's more: How can i change font size without changing the font-family (assuming that i have my own fonts in my plist).</p>
  
  <p>I tried:</p>
  
  <pre><code>cell.textLabel.font = [UIFont fontWithName:@"Sansation-Light" size:12.0];
  </code></pre>
  
  <p>But UIFont always want for me fontname/family. How can i avoid that and have one font to all my screen and changing only size?</p>
