The application discloses a method and device for obtaining application functions based on an iOS platform. The method for obtaining the application functions based on the iOS platform comprises the following steps: issuing a request for obtaining dynamic
library information to a dynamic
library information
server; receiving the dynamic
library information returned by the dynamic library information
server according to the request, wherein the dynamic library information at least includes the following information: a dynamic library ID, an entry view controller name, and a dynamic library download path; establishing a dynamic library
directory in the first sandbox path of an application according to the dynamic library ID and obtaining a
dynamic storage path; downloading a dynamic library from a dynamic library storage
server according to the dynamic library download path, and storing the dynamic library in the dynamic library
directory according to the
dynamic storage path; and loading the downloaded dynamic library into the application to be called by the application. By means of the embodiment of the application, the technical problem that the efficiency of updating an application on the
operating system of a
mobile device in the prior art is low is solved.
