how to add ARC in between of project

I am creating iPhone app and in between I need to use SDWebImage. For this I need to use ARC.

Any idea how to add ARC in between in project?

Note: In one file I have below content.

#if !__has_feature(objc_arc)
#error SDWebImage is ARC only. Either turn on ARC for the project or use -fobjc-arc flag
#endif

Where should I add -fobjc-arc flag?

Change from build settings

Project->Build setting->Objective-C Automatic Reference Counting  SET YES

If you need to remove ARC then Go to  Project->Build Phases->compile sources then find your file Which you need to remove ARC then set compile source '-fno-objc-arc'

If you are using xcode 4.6 then Select your target Target->Build Settingsand find Apple LLVM compiler 4.2 see in this section if Objective-c Automatic Reference Counting is set to YES, if not then just set it to YES. For older version of XCode you could change for Apple LLVM compiler 3.0
