How to debug customized static lib in XCode

[QQGuang]

Hello everyone,

I created a fat static lib by XCode 3.2.5, the target iOS is 4.2. I added this static lib into another iphone project. Is there any way that I can debug the static lib in the consumer project? For example, Eclipse and Visual studio provide the approach that allows developer to attach the source code of lib, then he can debug the lib. I want to know whether XCode aslo provides the same function. Can I achieve it by config a New Custom Executable?

Thanks in advance!
