adding pre defined frameworks like (AddressBook.framework,CoreGraphics.framework)etc. into my custom framework(a static library)?

i have made a framework with the help of this link:

http://www.cocoanetics.com/2010/05/making-your-own-iphone-frameworks-in-xcode/

but it does not tells how to add pre defined frameworks into it(such as AddressBook,CoreGraphics etc.).

when i tried adding the frameworks(predefined) to it ,it shows the error:

ld开发者_如何转开发: warning: unexpected dylib (/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/System/Library/Frameworks//AddressBook.framework/AddressBook) on link line

can anyone please suggest me how to add the predefined frameworks into the custom framework that i made...so that the end user is unknown of the dependent frameworks that i am using..????

thanks in advance.

You'll have add the predefined framework to your lib similar as we do in any project. But you also will have to add all those framework (added to your custom framework) to the project in which you are using your custom framework. So list all the included framework in the documentation of custom framework.
