User interface modification and usage tracking
Techniques are provided to facilitate tracking events associated with a user interface display of an application at runtime. In at least one implementation, one or more information structures that associate an event tracking indicator with a view selector are stored, wherein the event tracking indicator indicates an event to be tracked, and the view selector indicates one or more constraints to be matched to select a view of the application. During execution of the application, the view selector is evaluated with views used by the application to determine whether each of the one or more constraints of the view selector matches properties of the views. In response to determining that each of the one or more constraints of the view selector matches the properties of at least one of the views, an occurrence of the event indicated by the event tracking indicator associated with the view selector is tracked.
