问题描述
我需要使用带有后退按钮的UINavigation从SwiftUI打开UIViewController。
目前，我已经通过ViewControllerRepresentable和NavigationLink实现了它的工作，但是我有两个Navigation SwiftUI（带有后退按钮的NavigationLink）和没有后退按钮的默认UINavigation，并且我想执行默认的UINavigation并在后面按钮并隐藏SwiftUI（NavigationLink）导航。
struct UIKitVc : UIViewControllerRepresentable {
let navigationController = UINavigationController()
func updateUIViewController(_ uiViewController: UINavigationController,context: Context) {
}
func makeUIViewController(context: Context) -> UINavigationController {
let storyboard = UIStoryboard(name: "Main",bundle: nil)
let viewController = storyboard.instantiateViewController(withIdentifier: "SearchResult") as! SearchResultViewController
self.navigationController.addChild(viewController)
return self.navigationController
}
}
NavigationLink(destination: UIKitVc(){}
谢谢。
解决方法
如果您要使用NavigationView/NavigationLink，则无需使用UINavigationController，只需在UIViewController上使用可表示形式，例如
struct UIKitVc : UIViewControllerRepresentable {
func updateUIViewController(_ uiViewController: UIViewController,context: Context) {
}
func makeUIViewController(context: Context) -> UIViewController {
let storyboard = UIStoryboard(name: "Main",bundle: nil)
let viewController = storyboard.instantiateViewController(withIdentifier:
"SearchResult") as! SearchResultViewController
// ... make additional set up here if needed
return viewController
}
}
