Error while Google Analytics integration iOS

Error while Google Analytics integration iOS

I need to add google analytics to my iOS App,
I have implemented this 3 steps.
Step 1: Downloaded google analytics Library file and added this files to
project,
GAI.h
GAITracker.h
GAITrackedViewController.h -GAIDictionaryBuilder.h
GAIFields.h
GAILogger.h
libGoogleAnalyticsServices.a
CoreData.framework
SystemConfiguration.framework
libz.dylib
Step 2: Added this code in didFinishLaunchingWithOptions
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[GAI sharedInstance].trackUncaughtExceptions = YES;
[GAI sharedInstance].dispatchInterval = 20;
[[[GAI sharedInstance] logger] setLogLevel:kGAILogLevelVerbose];
[[GAI sharedInstance] trackerWithTrackingId:@"UA-XXXX-Y"];
}
Step 3: For example, suppose you have a "Home Screen" view that you want
to measure with a view controller header that looks like this:
@interface HomeViewController : UIViewController
I have updated this header to:
#import "GAITrackedViewController.h"
@interface HomeViewController : GAITrackedViewController
after doing this i am getting Error like,
