ClimbBar

Overview

iOS library that can extend a View that has scrollable elements such as UITableView and UIWebView.

As you can see in the example apps, the scroll bar hides the navigation bar.

Tips

When running on Xcode13.2 or later and iOS 15.2 or later, UINavigationController's UINavigatioBar may not work properly. so you may want to use UINavigationBar or UIView and etc,

Sample code

override func loadView() {
        super.loadView()
        title = "ViewController"
        let statusBarHeight = UIApplication.statusBarHeight
        let toHeaderBottom = statusBarHeight + (navigationController?.barHeight ?? 0)
        let conf = Configuration(range: statusBarHeight ... toHeaderBottom)

        climbBar = ClimbBar(configurations: conf,
                            scrollable: tableView)

        climbBar.emit { [weak self] state in
            guard let self = self else { return }
            self.navigationBar.setAlpha(alpha: CGFloat(state.progress))
            let navigtionFrame = CGRect(x: 0,
                                        y: state.originY,
                                        width: self.view.frame.size.width,
                                        height: 44)
            self.navigationBar.frame = navigtionFrame
        }
    }
extension UIApplication {
    static var statusBarFrame: CGRect {
        UIApplication.shared.connectedScenes
            .filter { $0.activationState == .foregroundActive }
            .map { $0 as? UIWindowScene }
            .compactMap { $0 }
            .first?
            .windows
            .filter { $0.isKeyWindow }.first?
            .windowScene?
            .statusBarManager?
            .statusBarFrame ?? .zero
    }

    static var statusBarHeight: CGFloat {
        statusBarFrame.size.height
    }
