iphone SDK: Why is my button not firing my function?
<p>We have place a button on a view. When we press it, nothing happens. It should be firing a function we have defined. This is what we have done.</p>

<p>We have used interface builder to map the touch up inside event to our function_A. We verify this by right clicking on our view controller and the mapping is there under the received actions section.</p>

<p>What else needs to be done to make this work?</p>
