Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate JJFloatingActionButton into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '11.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'JJFloatingActionButton'
end

Then, run the following command:

$ pod install

Manually

If you prefer not to use a dependency manager, you can integrate JJFloatingActionButton into your project manually.

Usage

Quick Start

let actionButton = JJFloatingActionButton()

actionButton.addItem(title: "item 1", image: UIImage(named: "First")?.withRenderingMode(.alwaysTemplate)) { item in
  // do something
}

actionButton.addItem(title: "item 2", image: UIImage(named: "Second")?.withRenderingMode(.alwaysTemplate)) { item in
  // do something
}

actionButton.addItem(title: "item 3", image: nil) { item in
  // do something
}

view.addSubview(actionButton)
actionButton.translatesAutoresizingMaskIntoConstraints = false
actionButton.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor, constant: -16).isActive = true
actionButton.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor, constant: -16).isActive = true

// last 4 lines can be replaced with
// actionButton.display(inViewController: self)

Configuration

Button appearance and behavior can be customized:

actionButton.overlayView.backgroundColor = UIColor(white: 0, alpha: 0.3)
actionButton.buttonImage = UIImage(named: "Dots")
actionButton.buttonColor = .red
actionButton.buttonImageColor = .white

actionButton.buttonAnimationConfiguration = .transition(toImage: UIImage(named: "X"))
actionButton.itemAnimationConfiguration = .slideIn(withInterItemSpacing: 14)

actionButton.layer.shadowColor = UIColor.black.cgColor
actionButton.layer.shadowOffset = CGSize(width: 0, height: 1)
actionButton.layer.shadowOpacity = Float(0.4)
actionButton.layer.shadowRadius = CGFloat(2)

actionButton.itemSizeRatio = CGFloat(0.75)
actionButton.configureDefaultItem { item in
    item.titlePosition = .trailing

    item.titleLabel.font = .boldSystemFont(ofSize: UIFont.systemFontSize)
    item.titleLabel.textColor = .white
    item.buttonColor = .white
    item.buttonImageColor = .red

    item.layer.shadowColor = UIColor.black.cgColor
    item.layer.shadowOffset = CGSize(width: 0, height: 1)
    item.layer.shadowOpacity = Float(0.4)
    item.layer.shadowRadius = CGFloat(2)
}

actionButton.addItem(title: "Balloon", image: UIImage(named: "Baloon")) { item in
    // Do something
}

let item = actionButton.addItem()
item.titleLabel.text = "Owl"
item.imageView.image = UIImage(named: "Owl")
item.buttonColor = .black
item.buttonImageColor = .white
item.action = { item in
    // Do something
}
