$ show AAChartModel/AAChartKit
AAChartKit is a production-ready iOS/macOS charting library that wraps the Highcharts JavaScript engine (v12.6.0) and renders interactive charts via WKWebView. The architecture is a clean Model-View separation: AAChartModel provides a chainable, declarative API for chart configuration, while AAChartView handles WebView lifecycle, JavaScript bridging, and event callbacks. A comprehensive hierarchy of option model classes (AAOptions, AAXAxis, AAPlotOptions, etc.) mirrors the full Highcharts configuration surface, allowing both high-level quick configuration and low-level full control. The library also supports JavaScript function injection via the @AAJSFunc macro for deep customization of tooltips, axes, events, and third-party Highcharts plugins, plus convenience categories for gradients, styles, and safe JS-string conversion. This is an application component library, not a data research project. The bundled demo app (AAChartKitDemo) showcases dozens of chart types from line/column/pie to advanced gauge/waterfall/boxplot with synthetic or hardcoded data. No data ingestion or analytics logic exists in the library itself—all data flows are user-supplied arrays or points passed to the chart objects. The codebase is mature, actively maintained with recent commits, and distributed via CocoaPods with an automated fastlane release pipeline. While the demo code is verbose and contains significant commented-out legacy support, the core charting API is well-structured, consistent, and demonstrates strong Objective-C craftsmanship.
The LLM identified 4 files worth highlighting for reuse:
Provides over 20 predefined, named gradient color schemes (oceanBlue, sanguine, etc.) as a self-contained Objective-C category. Easily extractable into any iOS app as a reusable color-theme library. Demonstrates data-driven design with static dictionaries and clean factory methods.
Implements a gradient constructor API that uses enumerations (AALinearGradientDirection) to declaratively define linear gradient start/end points. The pattern is isolated and could be reused for any vector-based drawing tool. Demonstrates clear, safe API design for color generation.
A category that safely converts arbitrary Objective-C strings into JavaScript string literals by escaping quotes, backslashes, and control characters. This is a common need in any WebView-bridging or JS-generation context and the implementation is self-contained and production-grade. Prevents JS syntax errors and injection issues.
Converts Objective-C arrays into valid JavaScript array strings, correctly handling nested arrays, dictionaries, booleans, and null values. Self-contained utility that can be extracted to other iOS/JS bridge projects. Demonstrates attention to JSON/JS type boundaries.
