Use Core Services Framework with IOS 4.3

I need use this framework with IOS 4.3 Scheme, How can i do this? I want to create a gallery app, i´ve created the interface but i need download some pictures.

I´ve used WSStub(server in objective c) and WSJava(client in java). I send picture code in Base 64, i receive this string decode and save in NSData but when i try to save in UIImage...开发者_开发问答 i showed a error.

After solve this problem adding Uikit framework and changing scheme to IOS 4.3, Core Service framework is uncompatible.....

Add this framework and mark as "Optional" (Xcode 4.2) "Weak Linking" prior versions.

And check for OS version in your code and do accordingly..
