FRAMEWORK PROVIDING APPLICATION PROGRAMMING INTERFACE FOR USER INTERFACES AND ANIMATION

Abstract:

The subject technology receives a command to initiate an application. The subject technology, in response to the command, generates a root node related to a root view of a first hierarchy of views representing a user interface (UI). The subject technology generates a child node of the root node for including in the first hierarchy of views, the child node corresponding to a first type of view. The subject technology generates a first child node of the child node for including in the first hierarchy of views, the first child node corresponding to a second type of view. The subject technology generates a graph including nodes, each node corresponding to a different attribute of the UI, wherein the root node, the child node, and the first child node have relationships with respective nodes from the graph.
