but xcode returns me some error.

 

 

Error's List: http://pastebin.com/TMimhsXF

 

 

i linked the framework in Build Phases and after this i downloaded the header and put in search path(/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/IOKit.framework) the path .

 

 

Now afterward i put the framework ( path of framework)in the framework folder. But when i compiled it xcode returned this error and if i try to remove that framework the problem persist.

How to resolve this problem?
