A wrapping method and device, a registration method and device, and a rendering apparatus are provided, which are related to a field of computer display technology. The specific implementation includes: receiving a creation instruction from a registry component, wherein the creation instruction includes an identification of a wrapper object to be registered, in a target code; and creating a corresponding wrapper object in the wrapper module, according to the identification of the wrapper object to be registered in the target code. In embodiments of the present application, a wrapper object may be quickly created in a wrapper module according to an identification of a wrapper object to be registered in a target code, which is beneficial to a reuse of a wrapper object, thereby improving code execution efficiency.
