Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0035] see figure 1 As shown, the embodiment of the present invention provides a method for constructing a list view in an IOS system, comprising the following steps: a method for constructing a list view in an IOS system comprises the following steps:

[0036] S1, the client obtains the preset section (content display module) protocol and cell (content display unit) protocol; the section protocol includes methods for obtaining the number of cells, methods for obtaining cells, methods for adding cells, methods for removing cells, and clearing The method of the cell; the cell protocol includes the reuse identifier of the cell, the layout configuration method of the cell, the assembly method of the cell, and the type of the cell;

[0037] S2, the client creates a corresponding section class according to each section style required to build a list...

Abstract

A method and system for creating list views in an iOS system, relating to the technical field of list expansion in an iOS system, comprising S1: a client acquires a preset section protocol and cell protocol; S2, the client creates a section type which achieves the section protocol and a cell type which achieves the cell protocol according to a section style and a cell style needed to create a list view; S3, the client acquires source data from a server to create the list view, and creates an example of the section type and an example of the cell type; S4, various call back methods from a data source mechanism are used to acquire information needed to create the list view, completing the creation of the list view; S5, various call back methods from a delegate mechanism are used to acquire list view layout configuration information, and setting layout configuration information of a section view and a cell view in the list.

Description

technical field [0001] The invention relates to the technical field of list expansion in the IOS system, in particular to a method and system for constructing a list view in the IOS system. Background technique [0002] The list in the IOS system is realized through the native control UITableView or UICollectionView provided by the IOS system. After providing datasource information and delegate information for UITableView or UICollectionView, the corresponding list effect can be realized. [0003] Since the cell used to display the content of the list is provided by the datasource, and the corresponding logic of the corresponding cell is processed in the corresponding delegate, in the IOS system, it is necessary to make a lot of judgments in the callback datasource information and delegate information to provide different Styles to provide different cells and handle the corresponding logic. If there are many types of cells in the list, a lot of judgment needs to be processe...
