Requirements

iOS 9.0+
Xcode 7.0+

Installation

CocoaPods:

Add folowing line to Podfile and run ‘pod instal’.


                                              
                                                pod ‘Sevruk-PageControl’

Or just drag and drop FoldingCell.swift file to your project

Usage with storyboard

Add a new UIView to storyboard.
Inherit view from PageControl.

In view controller create an outlet to a view from storyboard and you’re ready to go.

Here is code example that uses UIScrollView.


                                              
                                                import UIKit

import PageControl
class ViewController: UIViewController, UIScrollViewDelegate {
@IBOutlet weak var scrollView: UIScrollView!

@IBOutlet weak var pageControl: PageControl!
override func viewDidLoad() {

super.viewDidLoad()

scrollView.delegate = self

pageControl.numberOfPages = Int(scrollView.contentSize.width / scrollView.bounds.width)

}
func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {

let page = scrollView.contentOffset.x / scrollView.bounds.width

pageControl.currentPage = page

}

}

Usage without storyboard

Create a PageControl view and add it to your view hierarchy.


                                              
                                                let pageControl = PageControl()

addSubview(pageControl)

Setup pageControl with your needs.


                                              
                                                pageControl.numberOfPages = 5

pageControl.spacing = 14.0

pageControl.indicatorDiameter = 8.0

pageControl.currentIndicatorDiameter = 12.0

pageControl.indicatorTintColor = .darkGray

pageControl.currentIndicatorTintColor = .green

And update current page when needed.


                                              
                                                pageControl.currentPage = 1
