title: How can I update my NSTimer as I change the value of the time interval
body: <p>I have an <code>NSTtimer</code> implemented and it's working fine. I also have the time interval argument connected to a <code>UISlider</code> for the <code>iPhone</code>. However when I change it's value the <code>NSTimer</code> is still running at the original time interval it does not get updated. How can I implement an <code>NSTimer</code> and have it change it's time interval as the value of my <code>UISlider</code> changes. Below is the line I am using for the <code>NSTimer</code>.</p>
  
  <pre><code>[NSTimer scheduledTimerWithTimeInterval:mySlider.value 
                                   target:self 
                                 selector:@selector(myMethod) 
                                 userInfo:nil 
                                  repeats:YES];
  </code></pre>
  
  <p>I want it to constantly update it time interval with the value of the <code>UISlider</code>.</p>
