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

$ gem install cocoapods

CocoaPods 1.1+ is required to build TransitionableTab 4.2+.

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

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'TransitionableTab', '~> 0.2.0'
end

Then, run the following command:

$ pod install

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

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

github "Interactive-Studio/TransitionableTab" ~> 0.2.0

Run carthage update to build the framework and drag the built TransitionableTab.framework into your Xcode project.

If you prefer not to use either of the aforementioned dependency managers, you can integrate TransitionableTab into your project manually.

The usage of TransitionableTab is very simple

import TransitionableTab

class TabBarController: UITabBarController {

    override func viewDidLoad() {
        super.viewDidLoad()
        self.delegate = self
    }
}

extension TabBarController: TransitionableTab {

    func tabBarController(_ tabBarController: UITabBarController, shouldSelect viewController: UIViewController) -> Bool {
        return animateTransition(tabBarController, shouldSelect: viewController)
    }
}

public protocol TransitionableTab: UITabBarControllerDelegate {

    func transitionTimingFunction() -> CAMediaTimingFunction

    func transitionDuration() -> CFTimeInterval

    func fromTransitionAnimation(layer: CALayer, direction: Direction) -> CAAnimation

    func toTransitionAnimation(layer: CALayer, direction: Direction) -> CAAnimation
}
