DynamicBubble

DynamicBubble view gives app user power to construct speech/annotation bubbles using built-in control points and gestures.

Usage

Create bubble with initial set of tails

let bubble = DynamicBubble(centerPoint: view.center, originSides: [.down, .up, .left, .right], bubbleSize: CGSize(width: 200, height: 100))
// OR
let bubble = DynamicBubble(centerPoint: view.center, originSides: [.down, .up, .left, .right])
// OR
let bubble = DynamicBubble(centerPoint: view.center)

view.addSubview(bubble)

Customize colors, form and behaviour if needed

All properties have default values, so this step is optional.

// Appearance

bubble.textFont = UIFont(name: "Helvetica-Bold", size: 17.0)
bubble.textColor = UIColor.darkGray
bubble.textAlignment = NSTextAlignment.center
bubble.fillColor = UIColor.lightGray
bubble.strokeColor = UIColor.darkGray
bubble.controlsColor = UIColor.green
bubble.controlsRadius = 3

// Behaviour

/* Whether or not to show control points */
bubble.showsControls = true

/* Whether or not to lock user interaction */
bubble.reactsToControls = false

bubble.bringToFrontWhenActive = true
bubble.startsWithActiveTextBox = false
bubble.debugMode = false

Although changing most of these properties results in bubble being re-drawn, it's still recommended to call bubble.setNeedsDisplay() after that.

Add/Remove tails on the fly

At the moment, there is no built-in visual interface to add/remove tails (TBD), but there are methods to do this, so you can provide your users with whatever UI you want to call them.

bubble.addTailAtSide(.down)
bubble.removeTailAtSide(.up)

Built-in controls

There is pretty much everything for user to control bubble on screen.

Control points and gestures

Locked mode

Debug mode

ToDo's

• Add visual controls for tails add/remove actions
• Add support for higher rounding values (circle bubbles)
