Whereas porting my current UIKit based mostly app to SwiftUI I battle with a easy activity:
A UIViewControllerRepresentable holds a UINavigationController.
The UINavigationController shows VCs with completely different background colours. These should not utilized to the underside secure space. How can I alter this, in order that the secure space has the colour of the lively little one VC?
struct SomeSheetContent: UIViewControllerRepresentable {
func makeUIViewController(context: Context) -> UIViewController {
let firstVC = UIViewController()
firstVC.view.backgroundColor = .inexperienced
firstVC.title = "First VC"
firstVC.edgesForExtendedLayout = [.all]
firstVC.extendedLayoutIncludesOpaqueBars = true
let button = UIButton(sort: .system)
button.setTitle("Subsequent", for: .regular)
button.titleLabel?.font = .systemFont(ofSize: 20, weight: .daring)
button.addTarget(context.coordinator, motion: #selector(Coordinator.didTapButton), for: .touchUpInside)
firstVC.view.addSubview(button)
button.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
button.centerXAnchor.constraint(equalTo: firstVC.view.centerXAnchor),
button.centerYAnchor.constraint(equalTo: firstVC.view.centerYAnchor)
])
let navVC = UINavigationController(rootViewController: firstVC)
navVC.navigationBar.isTranslucent = false
navVC.edgesForExtendedLayout = [.all]
context.coordinator.navigationController = navVC
return navVC
}
func makeCoordinator() -> Coordinator {
Coordinator(self)
}
func updateUIViewController(_ uiViewController: UIViewController, context: Context) { }
class Coordinator: NSObject {
let guardian: SomeSheetContent
weak var navigationController: UINavigationController?
init(_ guardian: SomeSheetContent) {
self.guardian = guardian
}
@objc func didTapButton() {
let secondVC = UIViewController()
secondVC.view.backgroundColor = .orange
secondVC.title = "Second VC"
secondVC.edgesForExtendedLayout = [.all]
secondVC.extendedLayoutIncludesOpaqueBars = true
navigationController?.pushViewController(secondVC, animated: true)
}
}
}
