On the web, a pageview is defined as when the page loads, or when the URL changes.
In native mobile apps, a pageview is defined as when a user navigates to a new screen. Pageview events are captured when a new ViewController is presented to the user in an iOS app, and when a new Activity is presented to the user in an Android app.
For iOS apps, Heap implements additional logic to define a pageview. ViewControllers are the closest proxy for a “page” on iOS, but not all ViewControllers are pages. For screens with multiple ViewControllers, Heap captures a pageview event for a ViewController if it is the root ViewController for a window.
Additionally, Heap will issue a pageview event for the first screen a user is presented after foregrounding the app.
