title: How do i enable code blocks in an xcode iPhone project?
body: <p>I'm trying to enable code blocks in our iphone application so that i can run the static analyzer tool included with xcode.  I get this warning (or error, depending on which compiler i use) when i run the build and analyze task:</p>
  
  <blockquote>
    <p>/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.0.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIView.h:252:72: error: blocks support disabled - compile with -fblocks or pick a deployment target that supports them</p>
  </blockquote>
  
  <p>I've changed my deployment target to compiler default from iPhone OS 3.0, and i've changed the compiler from GCC 4.2 to LLVM 1.5 and LLVM GCC 4.2 with no luck.  I'm not sure what else I have to change to make this work, or where i need to add the -fblocks argument.  Does anyone know?</p>
