Sicky header for UIScrollView in Swift

Requirements

Installation

StickyScrollView is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'StickyScrollView'

Usage

** Swift 2.x **

import StickyScrollView

// you should use UIScrollViewDelegate here.
class ViewController: UIViewController, UIScrollViewDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()

        // ...
        // init your image here. (imageView)
        // ...

        // Initialize StickyScrollView
        let scrollView = StickyScrollView(frame: self.view.frame)
        scrollView.setStickyDisplayHeight(150)
        scrollView.setStickyImage(imageView)
        scrollView.delegate = self

        // add to view
        self.view.addSubview(imageView)
        self.view.addSubview(scrollView)
    }
}

** Object-C ** TBD

Advanced usage

set scrollView as sticky header view.

import StickyScrollView

// you should use UIScrollViewDelegate here.
class ViewController: UIViewController, UIScrollViewDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()

        // ...
        // init your image1 and image2 here. 
        // ...

        // Initialize header scroll view
        let bgScrollView = UIScrollView(frame: image1.frame)
        bgScrollView.addSubview(image1)
        bgScrollView.addSubview(image2)
        bgScrollView.contentSize = CGSize(width: image1.frame.width + image2.frame.width, height: image1.frame.height)

        // Initialize StickyScrollView
        let scrollView = StickyScrollView(frame: self.view.frame)
        scrollView.setStickyDisplayHeight(150)
        scrollView.setStickyView(bgScrollView)  // This will add bgScrollView into scrollView
        scrollView.delegate = self

        // add to view
        self.view.addSubview(scrollView)
    }
}

You can set scale ratio, alpha ratio or parallel moving ratio by your self, just call :

    scrollView.setScaleRatio(1)
    scrollView.setAlphaRatio(0.7)
    scrollView.setParallelRatio(0.4)
