1. An application creation method, applied to a terminal having a display device, wherein the method comprises: receiving, by the terminal, a property value of a component property configured by a user; generating a component model according to the property value of the component property; generating a component interface graphical element corresponding to the property value of the component property; mapping the component model as a function component model; creating a three-dimensional model of the function component graphical element by using a three-dimensional presentation space capability of a drawing tool preset on the terminal; searching for all function component graphical elements whose component type is an application programming interface (API) type; setting a display layer of the API-type function component interface graphical element to a bottom layer value such that the API-type function component interface graphical element is displayed at a bottom layer; setting a display layer of an input and output property graphical element corresponding to the API-type function component interface graphical element to one plus the display layer of the API-type function component interface graphical elementsuch that the affiliated input and output property graphical element is superimposed and displayed on the API-type function component interface graphical element; searching for all function component graphical elements whose component type is a visual user interface (UI) type; displaying the UI-type function component graphical element according to a display layer of the UI-type function component graphical element; establishing an association relationship between different function component graphical elements in a to-be-created application according to an operation performed by the user on the function component graphical element; generating a service function model according to the association relationship between the different function component graphical elements in the to-be-created application; and generating executable code of the to-be-created application according to the component model and the service function model.
