Screen sliding method using page as unit and having background loading function and cache logic function

Abstract

The invention provides a screen sliding method using a page as a unit and having a background loading function and a cache logic function. The screen sliding method comprises the steps that 10, a Scroll View is used as a screw sliding view container of a device; the length and the width of displayed pages are respectively set to be identical to the length and the width of the container; 20, a background thread is started, view data of the displayed pages within a cache area loading range are loaded in a cache area; 30, when screen sliding operation occurs to the device, the cache area is synchronously updated; 40, the loading rage of the cache area is detected, view data loading is conducted on the displayed pages in which view data loading has not been completed, and after loading is completed, the background thread is ended. The screen sliding method has the advantages of simplifying cache logic and enabling developers to achieve the functions.

Description

【Technical field】 [0001] The present invention specifically relates to a screen swiping method with page as a unit and with background loading and caching logic. 【Background technique】 [0002] When the view data cannot be fully displayed on the screen, the ScrollView (that is, the screen view) is usually used to move the viewport to display more content. When the content view cannot be fully displayed on the screen, only part of the content view is displayed. , the rest of the current non-visible content can be moved into the visible area by swiping the screen, but when the amount of view data is large, the process of loading data will become very time-consuming. If the loading time needs to be reduced, the program usually needs to implement it by itself Data background loading logic and caching logic. [0003] The commonly used background loading logic and caching logic mainly include: [0004] (1) Use the list controls provided by the system, such as UITableView for iOS...

AI Technical Summary

Problems solved by technology

[0006] For (1), these list controls only support vertically arranged views, and horizontal swiping cannot be achieved; for (2), due to the inconsistency of page elements and the uncertainty of the ScrollView view for the current visible area (ie The user can swipe to any area), which will lead to very complex judgment logic for elements that need to be loaded in the background, and it is difficult to abstract the background loading logic and cache logic into reusable modules; it can be seen that the existing background loading cache logic is not It is not only complicated but also inconvenient for technical developers to develop applications on the swiping screen
