ZGExpandableTable

用于 iOS 的可展开/折叠展示JSON对象的 UITableView

An collapsable (expandable) UITableView for showing JSON object iOS.

ZGExpandableTable is an iOS component designed to facilitate viewing JSON files on mobile devices. JSON files are often lengthy and hierarchical, making them challenging to view and navigate on a small screen. This component provides an expandable table view that allows users to view JSON content in a convenient, layer-by-layer manner.

Features

Recursively expand JSON hierarchies in a UITableView.
Easy integration with minimal setup.
Example project included to demonstrate functionality.

Example

To see ZGExpandableTable in action, check out the example project included in this repository. It uses a sample JSON from json.org to demonstrate content loading and display.

Example Code

Here's how you can set up and use ZGExpandableTable in your project:

NSString *examplePath = [[NSBundle mainBundle] pathForResource:@"example" ofType:@"json"];
NSData *exampleJSON = [NSData dataWithContentsOfFile:examplePath];

ZGExpandableTableController *tableController = [[ZGExpandableTableController alloc] initWithTableViewFrame:self.view.bounds style:UITableViewStylePlain];
UITableView *tableView = tableController.tableView;
[self.view addSubview:tableView];

[tableController loadJSON:exampleJSON];

Installation

ZGExpandableTable has been made into a pod. To use it, please add the following to your Podfile:

pod 'ZGExpandableTable', :git => 'https://github.com/ziggear/ZGExpandableTable.git'

Then run:

pod install

Project Design

Data Parsing

ZGExpandableTable uses a recursive approach to create ZGJSONNode objects because JSON is inherently recursive. Each node has an "expanded" property to indicate its expansion state.

Data Display

The component reads ZGJSONNode recursively and flattens it into a single-level ZGJSONNodeShowModel array. This makes it easy for UITableView to load the content. When a user taps on an item, the corresponding node's expanded state is updated, and the ZGJSONNodeShowModel array is reconstructed to enable unlimited JSON data expansion/collapse.

TableView Organization

ZGExpandableTableController helps create the UITableView but does not inherit from UIViewController. This design allows the caller to freely add the UITableView to their own View or ViewController.

Contributing

We welcome contributions to ZGExpandableTable! Here are some ways you can contribute:

Swift Version: We'd love to have a Swift version of this component. If you're interested in contributing, please submit a pull request.
UI Enhancements: Any improvements to make the JSON content display more visually appealing are highly appreciated.
