Today, I found GoogleAnalytics-iOS-SDK have new 3.0 version in Cocoapods. I upgraded and I try to modified the code of manual screen measurement as below:
id tracker = [[GAI sharedInstance] defaultTracker];
[tracker set:kGAIScreenName value:@"Detail View"];
[tracker send:[[GAIDictionaryBuilder createAppView] build]];
However, I always get error about kGAIScreenName is undeclared. Even I add GAIFields.h header, it still not work.
What did I miss?
You have to include two more things:
#import "GAIDictionaryBuilder.h"
#import "GAIFields.h"
Checking what's in GAIFields.h I can see that kGAIScreenName is there:
extern NSString *const kGAIScreenName; // synonym for kGAIDescription
Might be important point that the current Google Analytics is in beta, so using the latest downloadable SDK is always a good idea. What I tried and what is working currently for me is Version: 3.0 (August 16, 2013).
I am using a hardcoded value of @"&cd" for kGAIScreenName and it works perfectly. Found the value in the Measurement Protocol documentation at Google https://developers.google.com/analytics/devguides/collection/protocol/v1/devguide#apptracking
