IOS 11 navigation element with user interaction enabled does not work

Question

Hi, I have a navigation element, there is a view that contains two labels that I added userInteractionEnabled for the view inside the navigation element (IBoutleted as navigationView)

navigationView.isUserInteractionEnabled = true

mainTitleClicked = UITapGestureRecognizer(target: self, action: #selector(mainTitleTapped))

self.navigationView.addGestureRecognizer(mainTitleClicked)

This worked in iOS 10, but when I run the same code in xcode 9, the iOS 11 UI gets messed up and the gesture is not recognized

IOS version 10

IOS Version 11

What should I change to make it work on ios 11

thanks for the help

Answer 1

I solved it by adding the following code

if #available(iOS 11.0, *) {
        self.navigationController?.navigationBar.prefersLargeTitles = false
        self.navigationItem.largeTitleDisplayMode = .automatic
        var width = navigationView.sizeThatFits(CGSize(width: CGFloat.greatestFiniteMagnitude, height: CGFloat.greatestFiniteMagnitude)).width - 15.0
        let height = navigationView.sizeThatFits(CGSize(width: CGFloat.greatestFiniteMagnitude, height: CGFloat.greatestFiniteMagnitude)).height

        let screenSize: CGRect = UIScreen.main.bounds
        let windowWidth = screenSize.width
        width = windowWidth * 0.55

        let widthConstraint = navigationView.widthAnchor.constraint(equalToConstant: width)
        let heightConstraint = navigationView.heightAnchor.constraint(equalToConstant: height)

        heightConstraint.isActive = true
        widthConstraint.isActive = true
    }

:

if #available(iOS 11.0, *) {
            self.navigationController?.navigationBar.prefersLargeTitles = false
            self.navigationItem.largeTitleDisplayMode = .automatic
            var width = popUserChatView.sizeThatFits(CGSize(width: CGFloat.greatestFiniteMagnitude, height: CGFloat.greatestFiniteMagnitude)).width - 15.0
            let height = popUserChatView.sizeThatFits(CGSize(width: CGFloat.greatestFiniteMagnitude, height: CGFloat.greatestFiniteMagnitude)).height


            let screenSize: CGRect = UIScreen.main.bounds
            let windowWidth = screenSize.width
            width = windowWidth * 0.55

            let widthConstraint = popUserChatView.widthAnchor.constraint(equalToConstant: width)
            let heightConstraint = popUserChatView.heightAnchor.constraint(equalToConstant: height)

            heightConstraint.isActive = true
            widthConstraint.isActive = true
        }

ViewDidLoad()
