This example demonstrates UIKit physics-based animation on iOS, where a small red square falls under simulated gravity within a 300-by-100-point view. It shows how a UIView child is added to a parent container, given a red background color, and then subjected to a UIGravityBehavior from the UIDynamicAnimator class. The code initializes the animator with the parent view as its reference view, then attaches the gravity behavior to the subview, causing it to accelerate downward. The rendering stays within the standard UIKit view hierarchy, with no external data sources involved.

Testing how to animate a NSBox on the screen.

This example demonstrates how to animate a red NSBox across a macOS window using AppKit’s animation proxy. The code creates a floating NSPanel, configures it with a custom style mask, and disables the minimize and zoom buttons. An NSBox is added as a subview to the panel’s flipped content view, then its frame origin is moved via the `animator()` proxy to trigger a smooth animation. The implementation relies on `NSThread.mainThread().threadDictionary` to manage the panel’s lifecycle for repeat executions.

Getting a CALayer to animate implicitly

This example demonstrates implicit CALayer animation on macOS, where a red sublayer moves from one position to another when its `position` property changes. The code uses AppKit’s `NSPanel` and `NSView` with `wantsLayer` enabled, alongside Core Animation’s `CALayer` and `CATransaction` to animate the layer’s position over one second. The layer’s bounds and blue border are set explicitly, while the sublayer’s movement is triggered via a `setTimeout` callback, showing how implicit animations work for layer properties.

interesting quartz tricks

This example demonstrates how to draw a social-media-style post card using Core Graphics and Quartz 2D on iOS. It shows a rounded container with a gradient “Like” bar at the bottom, which includes text labels (“Like,” “Comment”) and vertical dividers, plus a placeholder for an avatar. The code uses `UIBezierPath` for shapes, `CGGradientCreateWithColors` for the bar’s linear gradient, and shadow declarations via `CGContextSetShadowWithColor`. The rendering is entirely procedural, with no external data source, focusing on manual layout and styling through Core Graphics calls.

Cocoa

This example shows a custom slider control built with Cocoa’s AppKit framework, using an `NSView` subclass to render a gradient-filled, rounded rectangular track. The view applies a linear gradient via `NSGradient` and sets a corner radius using layer-backed properties (`wantsLayer`, `layer.cornerRadius`). The code also attempts to load an image from a file named `knob.png` for the slider’s thumb, though the actual drawing of that image is commented out. The gradient and angle properties are exposed, with setters that trigger redraws via `setNeedsDisplay:`. The data source is the referenced image file, while the rendering relies on `drawRect:` and `drawInRect:angle:`.

This example presents a full-screen, animated canvas of randomly colored square pixels that continuously redraws itself. It shows how a simple generative pattern can create a dynamic, shifting mosaic across the entire browser window. The code uses the Canvas 2D API with `fillRect` and `requestAnimationFrame` to refresh the display, while each frame assigns new random RGB values to every pixel block. The visualization responds to window resizing by updating the canvas dimensions, and it is rendered inside a draggable, resizable widget container.

Before applying the style guide

This example shows an Objective-C iOS view controller that manages a sign-in form, demonstrating how UI state updates based on text-field validation. It uses UIKit’s `UITextField` targets and `IBAction` to trigger validation on each edit, while the `updateUIState` method toggles background colors (yellow for invalid) and disables the sign-in button until both username and password exceed three characters. The code relies on `RWDummySignInService` to simulate asynchronous sign-in, which disables all controls during the request and hides or shows a failure label upon completion. It does not use any charting or visualization libraries, instead illustrating a simple state-driven interface pattern with native Cocoa Touch APIs.

Animating the background blur of a NSView that is layer backed

This example demonstrates a layer-backed NSView that fades in with a Gaussian background blur over a fixed image, then reverses the effect. The animation cycles through a state where the view’s background transitions from fully transparent to a blurred, semi-transparent black overlay, using CABasicAnimation and CAAnimationGroup to coordinate opacity and blur radius changes. The code leverages the Objective-C libraries (NSView, CALayer, CIFilter) and the inherent layer-backing system to apply the blur filter via `CIGaussianBlur`, with timing controlled by `CAMediaTimingFunction`. The data source is a local PNG image file, and the animation runs on a timer, hiding the view after the fade-out completes.

Untitled

This example demonstrates a simple animation where a black square container transitions its background color to red over one second. The visualization uses the D3.js library's `d3.select` function to target the HTML element and applies a `transition().duration(1000).style("background-color", "red")` chain. The code also includes an unexecuted fragment that reads population data from a CSV file using `d3.csv` and scales values by a factor of 1000 before rendering rectangles to an SVG. The animation highlights D3's ability to smoothly interpolate CSS style changes.
