title: Creating a custom slider for iPhone
body: <p>I need to create a custom vertical slider for my iPhone app, simply because the UISlider is to narrow. It is going to be used as a throttle "stick" for my remote controlled helicopter. 
  I managed to rotate the slider in xcode with </p>
  
  <pre><code>throttleSlider.transform = CGAffineTransformMakeRotation(3*M_PI_2);
  </code></pre>
  
  <p>but I think this is quite ugly since the slider still appear horizontally on my storyboard. Also, I can not find anyway to make the slider wider.</p>
  
  <p>How will I approach this problem?</p>
  
  <p>Thank you. </p>
