适用于 iOS 的 Google Analytics（分析） - 手动屏幕跟踪不起作用

Question

I've got a problem with screen tracking on iOS. I'm doing it like it's presented in sample app from Google:

    let tracker = GAI.sharedInstance().defaultTracker
    tracker.set("My screen", value: "Value")
    tracker.send(GAIDictionaryBuilder.createScreenView().build() as [NSObject : AnyObject])

And it doesn't work. It's correctly tracking events though, and when I'm subclassing View Controller as GAITrackedViewController it's tracking screens. But, I don't want to subclass my view controllers just to track screens. Does anyone got an idea?

You do not have to inherit your ViewControllers, just do this:

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)
    let googleTracker = GAI.sharedInstance().trackerWithTrackingId("UA-YOUR_TRACKER_ID")
    googleTracker.set(kGAIScreenName, value: "MyPageName")
    let builder = GAIDictionaryBuilder.createScreenView()
    googleTracker.send(builder.build() as [NSObject : AnyObject])
}

Of course you do not need to create the "googleTracker" object every time, do it on some central place and get it from there.
