Error while Google Analytics integration iOS

问题

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,

duplicate symbol _OBJC_CLASS_$_GAIUtil in:
    /Users/Supriya/Desktop/BTS 2.0/BTS/BTS/Library/libGoogleAnalytics_debug.a(GAIUtil.o)

EDIT: I have added this frameworks and Library in my projects which i told you above.

You have to delete one of these two libGoogleAnalytics_debug.a, libGoogleAnalyticsServices.a from your project. Find out, where they are and how they are generated and make so, that only one of these libraries is involved in your build. I suppose, one of them is added by you and the other is automatically created and added, when you build.
