Simple parallax header for UIScrollView.

HPScrollViewController's viewDidLoad()
can't override in inherited class
Could you append scrollViewDidScroll
for HPScrollViewDelegate?
parallaxHeaderDidScroll
method return strange values even before my scrolling.(when initialized?)
func parallaxHeaderDidScroll(_ parallaxHeader: HPParallaxHeader) {
var progress = parallaxHeader.progress
print(progress)
}
In the first loaded view controller.
it logged 1
, 0
before scrolling.
final class MyContainerViewController: HPScrollViewController {
override var preferredStatusBarStyle : UIStatusBarStyle {
return UIStatusBarStyle.lightContent
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
if #available(iOS 13.0, *) {
let appearance = UINavigationBarAppearance()
appearance.configureWithTransparentBackground()
appearance.titleTextAttributes = [.foregroundColor: UIColor.white]
appearance.backgroundColor = UIColor(red: 0.0/255.0, green: 123.0/255.0, blue: 187.0/255.0, alpha: 1.0)
navigationController?.navigationBar.scrollEdgeAppearance = appearance
navigationController?.navigationBar.standardAppearance = appearance
}
}
it can't mack white header under clock.
Or I want the option for it.
It can't access scrollView
extension HeaderViewController: HPParallaxHeaderDelegate {
func parallaxHeaderDidScroll(_ parallaxHeader: HPParallaxHeader) {
// can't access scrollView
if let scrollView = parallaxHeader.scrollView {
trackingOffset(scrollView)
}
}
'scrollView' is inaccessible due to 'internal' protection level
I think there are many MXParallaxHeader
users.
I hope migration from Objective-C to Swift version.
