Problems solved by technology
However, the disadvantage of this method is also very obvious
On the one hand, it will take up a lot of performance resources, increase power consumption, and affect the stability and fluency of the system
On the other hand, it is also likely to conflict with regular music players
And more importantly, applications with similar mechanisms may not pass the official review of the IOS system
[0005] It can be seen that there is a lack of a method for downloading video files in the background for a long time and multitasking under the IOS system in the prior art

Embodiment Construction
[0044] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

The invention discloses a method and a system for downloading a video file at the background in an IOS system. The method comprises the following steps of making downloading task configuration of an application program in advance; on the basis of the downloading task configuration, creating a downloading task aiming at a specific video file in the application program; executing the download task; after the application program enters the background, continuously executing the currently executing download task; if the execution of the currently execution download task is completed, waking up the application program and entering the background waking time; judging whether an unexecuted download task exists or not; if the unexecuted download task exists, executing a preset delay event in the background waking time so as to execute the unexecuted download task. The method and the system have the advantages that the long-time continuous background downloading is realized; the IOS system rule does not need to be disobeyed; excessive performance resources do not need to be occupied; the processing mode on the download task of execution failure is realized, so that the method has good fault tolerance.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular, relates to a method and system for downloading video files in the background of an IOS system. Background technique [0002] In the IOS system, there is a very unique background operation mechanism. The system can intelligently manage the applications running in the background, and limit the running of background programs to a certain extent, so as to ensure the overall stability and smoothness of the system. According to the rules of the IOS system, except for a few programs that need to run in the background for a long time, such as positioning or music playback, most programs will be automatically closed after retreating to the background for a certain period of time. [0003] Many current online video applications can download video files to local storage for offline viewing. However, based on the above-described IOS system rules, the video application pro...
