This class is not key value coding-compliant for the key

Name of affected component: Campaign Measurement iOS tutorial

Objective-C

Issue summary:
There is a critical bug in Campaign Measurement iOS tutorial causing an app to 
crash 
(https://developers.google.com/analytics/devguides/collection/ios/v3/campaigns#g
eneral-campaigns).

There is this line of code in the method 
application:openURL:sourceApplication:annotation

    if(![hitParams valueForKey:kGAICampaignSource] && [url host].length !=0) {

Calling *valueForKey* on GAIDictionaryBuilder causes an app to crash with "This 
class is not key value coding-compliant for the key". It should be replaced 
with *get* method of GAIDictionaryBuilder.

I have same issue and solve with above comment which is valueForKey should be 
replaced with "get" method of GAIDictionaryBuilder. 

Note: get method created in GAIDictionaryBuilder class.

The documentation for campaigns needs to be changed to the fix mentioned above.
