how to pass uislider value through delegate?
<p>My programe does get valuse from UISlider and send the value to its superclass through protocol.</p>

<p>child.h</p>

<pre><code>-(void) valueA:(NSInteger *)vA valueB:(NSInteger *)vB;
</code></pre>

<p>and I call it in child.m</p>

<pre><code>[self.delegate valueA:sliderA.value valueB:sliderB.value];
</code></pre>

<p>but it returns error says "incompatible type for argument 1 of valueA:vA:"
do I have to parse the value before I pass the value? or I just made wrong parameter? </p>
