conditional link library when switch build from simulator to device
<p>Hey
I have an iphone application using the third party library from my customer. They provide me two static library one for simulator and one for device. How can I change setting to allow me set to project setting to build against right library when project change configuration? can i use --framework flag? if it is, how I can do that?</p>

<p>Thanks in advanced. </p>
