iphone: get User Defined variable in Target's setting by code?

Question

My project have multi-targets. Each target has its own Class file for setting stuff. I want to store that Class name in a target setting (Info.plist or Target's Building setting). So that I can define which class I need to use in each target based on this setting.

According to this question, I put "a target-specific User Defined variable" in each Target's Building Setting.

But don't know how to get it back in my code?

As the Info.plist file is preprocessed too, you can use this approach:

Define a User defined setting in your build settings, for Example CLASS_NAME. And a key to your Info.plist-file. Name the key CLASS_NAME and set the value to ${CLASS_NAME}.

You can then access this setting by:

NSString* className = [[[NSBundle mainBundle] infoDictionary] valueForKey:@"CLASS_NAME"];
