Using the parallax header with a UITableView that has header sections causes scrolling issues with the header sticking in the view until scrolling to another header section.

class UserHomeViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    var tabBar:TabBar?
    let sections = ["Drafts", "Scheduled", "Past"]
    
    @IBOutlet weak var eventsTableView: UITableView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        initUI()
    }
    
    /// Initialize any UI components
    private func initUI(){
        initTableView()
        tabBar = TabBar.init(self.view, navController: self.navigationController!, isVendor: false, selectedTab: 0)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
    
    /// Initialize the trip table view
    fileprivate func initTableView(){
        
        eventsTableView.register(UINib(nibName: "TripTableViewCell", bundle: nil), forCellReuseIdentifier: "TripTableViewCell")
        eventsTableView.rowHeight = 60
               
        eventsTableView.parallaxHeader.view = (Bundle.main.loadNibNamed("ParallaxHeaderView", owner: self, options: nil)![0] as? UIView)!
        eventsTableView.parallaxHeader.height = 120
        eventsTableView.parallaxHeader.minimumHeight = 0
        eventsTableView.parallaxHeader.mode = .topFill
    }
    
    /// Set the number of entries in table view
    /// - parameter tableView: table view we are getting the size of.
    /// - parameter section: section of the table view we are getting the size of.
    /// - returns: the size of the table view.
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        
        var size = 0
        
        switch section {
        case 0:
            size = 5
        case 1:
            size = 5
        case 2:
            size = 5
        default:
            size = 0
        }
        
        return size
    }
    
    /// Set the values for the table view cells
    /// - parameter tableView: table view that the cell is being initialized for.
    /// - parameter indexPath: row in the table view that the cell will be placed.
    /// - returns: the initialized table view cell.
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        
        let cell = tableView.dequeueReusableCell(withIdentifier: "TripTableViewCell", for: indexPath) as! TripTableViewCell
        
        return cell
    }
    
    func numberOfSections(in tableView: UITableView) -> Int {
        return sections.count
    }
    
    func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
        return 30.0
    }
    
    func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        
        let header = Bundle.main.loadNibNamed("EventsHeaderView", owner: self, options: nil)![0] as! EventsHeaderView
        header.headerLabel.text = sections[section]
        
        return header
    }
}

Hi, Thanks for this amazing library i've noticed there's an issue with iOS 10 when scroll to top and when navigation bar is Translucent

You can see the different bellow

iOS 11 - Working correctly iOS 10 - has an issue

Hello, I completed conversion to swift 4.2.

I tested everything and it works fine. Please accept pull request if it's possible.

And thanks for nice project!

Hi All,

I'm having having an issue where the header is shown bellow the status bar. So the header.y == statubar.maxY. The tableview's.y == 0. So the content is shown bellow the status bar. Can anyone help?

Thanks in advance!

Hi, I'm implementing a comments tableview with a parallax header. To show insertion of comments I'm using scrollToRow but when I use it on a tableView with parallax header, the table is scrolled down to the bottom. I've tested it without parallax header scrolling works exactly as needed. Also my table style is plain and I'm using a section header as a comment having replies as cells.

Hi 👋

Thanks for your awesome library! 👍 I just notice a small constraint error. If you:

1. Launch your example project
2. Test one tableView with parallaxHeader using centerFill as mode
3. You'll see an error in the logs "Unable to satisfy constraint... attempt recovering by breaking constraint centerX"

I fixed it! Works like a charm ✨

Ignore Safe Areas

Issue: Safe area is been used to pin contentView without taking into consideration some of other custom layouts, for example having an imageView as header covering the whole navBar including safeAreas.

This PR adds an optional flag were users can set it to true if their headers fill the whole safe area.

 /// This is to support a usecase where a parallax header is being used at the very top edge of the screen.
/// If this is set to true then the header will be pinned at the top of the scrollView. Default value is `false`
    public var ignoreTopSafeAreaInset:Bool = false

Usage: myScrollview.parallaxHeader.ignoreTopSafeAreaInset = true

Swift Package Manager (SPM)

This PR also includes SPM support without any changes to source code structure. Only a package manifest file is added which points to the right source files.

Note: The reason to include SPM support on a single PR is because I am using this branch in my project.

This reverts commit 77814dc61a2715a76f6f537d6de44e613d927060.

We're using the parallax header on the very top of one of our screens. This change leads to a top offset (44pt) on newer "notch devices" as we don't want to constraint to the safeArea but, to the very top of the screen.

Hi, I'm implementing a comments tableview with a parallax header.

I've tested it without parallax header scrolling works exactly as needed. Also my table style is plain and I'm using a section header as a comment having replies as cells. I've tested this in MXParallaxHeader too and it also produces same problem. Kindly let me know if anything I'm missing here or if you can relate the issue. Thanks

hi there , recently I updated my app and is giving me some syntax changes , I was able to unlock your code to make them, but it would be super awesome If you could take some of your time to make it avalaiable for swift 5 please
