GAITrackedViewController and UITableViewController

Question

With Google Analytics for iOS v2 Google suggests subclassing their GAITrackedViewController class in place of UIViewController. What do we do in the case of UITableViewController?

source

#import "GAITrackedViewController.h"  @interface AboutViewController : GAITrackedViewController 

Answer 1

Manual Screen Tracking

Remember that extending GAITrackedViewController is only one way to track screen views. The manual way is just as easy.

SDK v2

- (void)viewDidAppear:(BOOL)animated {     [super viewDidAppear:animated];          // returns the same tracker you created in your app delegate     // defaultTracker originally declared in AppDelegate.m     id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];      // manual screen tracking     [tracker sendView:@"Home Screen"]; } 

SDK v3

#import "GAI.h" #import "GAIFields.h" #import "GAIDictionaryBuilder.h" 

...

- (void)viewDidAppear:(BOOL)animated {     [super viewDidAppear:animated];          // returns the same tracker you created in your app delegate     // defaultTracker originally declared in AppDelegate.m     id tracker = [[GAI sharedInstance] defaultTracker];      // This screen name value will remain set on the tracker and sent with     // hits until it is set to a new value or to nil.     [tracker set:kGAIScreenName            value:@"Home Screen"];      // manual screen tracking     [tracker send:[[GAIDictionaryBuilder createScreenView] build]]; }

Answer 2

In an effort to clean up the manual tracking code in my Swift project, I created the following UIViewController extension.

extension UIViewController {     func trackScreenView(screenName: String) {         let tracker = GAI.sharedInstance().defaultTracker         tracker.set(kGAIScreenName, value: screenName)         tracker.send(GAIDictionaryBuilder.createAppView().build())     } } 

It's probably not proper to use an extension this way, as I'm not using any properties from the UIViewController, but it's a convenient way that feels better than a global method. If you don't mind using your class name instead of a nicely formatted name, you could even use the NSStringFromClass(self.dynamicType) to get the ViewController class name like so:

extension UIViewController {     func trackScreenView() {         let tracker = GAI.sharedInstance().defaultTracker         tracker.set(kGAIScreenName, value: NSStringFromClass(self.dynamicType))         tracker.send(GAIDictionaryBuilder.createAppView().build())     } } 

This allows me to add manual tracking from my UITableViewControllers with just the following code:

override func viewDidAppear(animated: Bool) {     super.viewDidAppear(animated)     trackScreenView("Detail View")  //Or call this without any arguments if using the NSStringFromClass idea  } 

Nice and clean. Enjoy!
