ABStackKit

Written in Swift 5, presenting a colourful scrollable StackView. Simply manage the lifecycle of the StackView via StackViewEmbeddable protocol or subclassing the StackViewController. Additionally if you need to colour its background or apply rotation on it or just use it on a portion of your view, this is the one library that you need. Only Swift compatible.

Installation with CocoaPods

CocoaPods is a dependency manager for both Swift and Objective-C. ABStackKit is available through CocoaPods. You can install it with the following command:

$ gem install cocoapods

Podfile

To install it, simply add the following line to your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '12.0'

target 'TargetName' do
    pod "ABStackKit"
end

Then, run the following command:

$ pod install

Usage

Sample Code (Swift)

import ABStackKit

// setup the stack view
let stackView = StackView(frame: view.frame)
stackView.delegate = self

// embedd to your controller's view
view.addSubview(stackView)
view.addEdgeAnchors(onView: stackView)

// implement methods from StackViewEmbeddable protocol
func willConfigure(_ stackView: StackView) {
    stackView.axis = .vertical
    stackView.alignment = .center
    stackView.distribution = .equalSpacing
    stackView.spacing = 9
    stackView.animDuration = 0.99
    stackView.clockRadian = .pi/99
    stackView.backgroundColor = .red
    stackView.layoutMargins = UIEdgeInsets(top: 9, left: 9, bottom: 9, right: 9)
}
    
func numberOfChildViews() -> Int {
    return 6
}
    
func childViewForIndex(_ index: Int) -> UIView {
    let childView = UIView(frame: CGRect(x: 0, y: 0, width: view.bounds.width/2, height: view.bounds.height/2))
    childView.backgroundColor = .blue
    
    let lblNumber = UILabel()
    lblNumber.text = "View \(index+1)"
    lblNumber.textColor = .white
    childView.addSubview(lblNumber)
    childView.addCenterXYAnchors(onView: lblNumber)
    
    return childView
}

func didSelectChildView(_ view: UIView, index: Int) {
    if let height = view.constraint(withIdentifier: ConstraintTag.H)?.constant {
	    view.constraint(withIdentifier: ConstraintTag.H)?.constant = height/2
	    UIView.animate(withDuration: 0.25) {
	        view.superview?.layoutIfNeeded()
	    }
    }
}

func didScrollToChildView(_ view: UIView, index: Int) {}
