DynamicButton is a powerful flat design button written in Swift to display hamburger button like with animated transitions between style updates. It also allows you to create your own custom symbol / style buttons!

Requirements

• iOS 8.0+ / tvOS 9.0+
• Xcode 10.0+
• Swift 5+

Usage

Basics

Here is how to create a button and setting its style:

import DynamicButton

let dynamicButton = DynamicButton(style: .hamburger)
// Equivalent to
// let dynamicButton   = DynamicButton()
// dynamicButton.style = .hamburger

// Animate the style update
dynamicButton.setStyle(.close, animated: true)

Customization

Button appearance and behavior can be customized using different properties:

let dynamicButton                 = DynamicButton()
dynamicButton.lineWidth           = 3
dynamicButton.strokeColor         = .black
dynamicButton.highlightStokeColor = .gray

Supported Symbol Styles

Here is the symbol list (DynamicButton.Style) already implemented by the library:

• .arrowDown: downwards arrow ↓
• .arrowLeft: leftwards arrow ←
• .arrowRight: rightwards arrow →
• .arrowUp: upwards arrow ↑
• .caretDown: down caret ⌄
• .caretLeft: left caret ‹
• .caretRight: left caret ›
• .caretUp: up caret: ⌃
• .checkMark: check mark ✓
• .circleClose: close symbol surrounded by a circle
• .circlePlus: plus symbol surrounded by a circle
• .close: close symbol X
• .dot: dot symbol .
• .download: downwards triangle-headed arrow to bar ⤓
• .fastForward: fast forward ≫
• .hamburger: hamburger button ≡
• .horizontalLine: horizontal line ―
• .horizontalMoreOptions: horizontal more options …
• .none: no style
• .pause: pause symbol ‖
• .play: play symbol ►
• .plus: plus symbol +
• .stop: stop symbol ◼
• .reload: reload symbol ↻
• .rewind: rewind ≪
• .verticalLine: vertical line |
• .verticalMoreOptions: vertical more options ⋮
• .location: location symbol

Custom symbols

To create your own symbols you have to create an object (or struct) that conforms to the DynamicButtonBuildableStyle protocol:

/// Diagonal line style: \
struct MyCustomLine: DynamicButtonBuildableStyle {
  let pathVector: DynamicButtonPathVector

  init(center: CGPoint, size: CGFloat, offset: CGPoint, lineWidth: CGFloat) {
    let r = size / 2
    let c = cos(CGFloat.pi * 0.3)
    let s = sin(CGFloat.pi * 0.3)

    let p1 = CGMutablePath()
    p1.move(to: CGPoint(x: center.x + r * c, y: center.y + r * s))
    p1.addLine(to: CGPoint(x: center.x - r * c, y: center.y - r * s))

    pathVector = DynamicButtonPathVector(p1: p1, p2: p1, p3: p1, p4: p1)
  }

  /// "MyCustomLine" style.
  static var styleName: String {
    return "MyCustomLine"
  }
}

myButton.style = .custom(MyCustomLine.self)

Note that a symbol can not have more than 4 paths.

And many more...

Installation

CocoaPods

Install CocoaPods if not already available:

$ [sudo] gem install cocoapods
$ pod setup

Go to the directory of your Xcode project, and Create and Edit your Podfile and add DynamicButton:

$ cd /path/to/MyProject
$ touch Podfile
$ edit Podfile
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'

use_frameworks!
pod 'DynamicButton', '~> 6.2.1'

Install into your project:

$ pod install

Open your project in Xcode from the .xcworkspace file (not the usual project file):

$ open MyProject.xcworkspace

You can now import DynamicButton framework into your files.

Carthage

Carthage is a decentralized dependency manager that automates the process of adding frameworks to your Cocoa application.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate DynamicButton into your Xcode project using Carthage, specify it in your Cartfile file:

github "yannickl/DynamicButton" >= 6.2.1

Swift Package Manager

You can use The Swift Package Manager to install DynamicButton by adding the proper description to your Package.swift file:

import PackageDescription

let package = Package(
    name: "YOUR_PROJECT_NAME",
    dependencies: [
        .package(url: "https://github.com/yannickl/DynamicButton.git", from: "6.2.1")
    ],
    // ...
)

Note that the Swift Package Manager is still in early design and development, for more information checkout its GitHub Page.

Manually

Download the project and copy the DynamicButton folder into your project to use it in.
