iPhone Slider Sensitivity
<p>I have custom slider that I use the following touch event to respond to:</p>

<pre><code>[bSlider addTarget:self action:@selector(sliderAction:) forControlEvents:UIControlEventValueChanged];
</code></pre>

<p>I find it very difficult to use, it does not respond to touches about 50% of the time.  Compared to the volume slider with the music player that works great every time you touch it.  Are there any secrets to creating a slider in code that will make it more responsive?</p>
