I had download Xenofex-MultiColumnTableViewForiOS-0b3fa88 library and plan to use it in my iOS project.

May i know what is step to import and link this library to my project? Just drag and drop the unzipped folder to my project?

I had drag the needed file to my project and try to run it.

The compiler prompt me error below Undefined symbols for architecture i386: "_OBJC_METACLASS_$_CALayer", referenced from: _OBJC_METACLASS_$_EWHeaderHighlightLayer in EWHeaderHighlightLayer.o "_OBJC_CLASS_$_CALayer", referenced from: _OBJC_CLASS_$_EWHeaderHighlightLayer in EWHeaderHighlightLayer.o objc-class-ref in EWMultiColumnTableView.o "_OBJC_CLASS_$_CATransaction", referenced from: objc-class-ref in EWMultiColumnTableView.o "_kCATransactionDisableActions", referenced from: -[EWMultiColumnTableView highlightColumn:] in EWMultiColumnTableView.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Can anyone advice on this?

By the look of the linker errors, you need to add the QuartzCore framework to your project. This is where the CALayer class is implemented, along with a load of other things.

There are instructions on how to do this in the top-rated answer to this SO question: Adding quartzcore to xcode 4 for iOS.
