iphone - locating incompatible code
<p>I have a code with two targets that uses functions specific to iOS 4 and others compatible with 3.0+.</p>

<p>I would like to make a final revision on the code to see if everything is fine. In other words, to see if there's no function meant for iOS4 being called when compiling for iOS 3.x target.</p>

<p>Is there a way to list, during compilation, any functions being called that doesn't belong to the desired version for the target?  </p>

<p>thanks in advance.</p>
