问题 Can you use a NavigationLink as a Menu 's item in swiftUI? It seems to do just nothing: Menu { NavigationLink(destination: Text("test1")) { Text("item1") } NavigationLink(destination: Text("test2")) { Text("item2") } } label: { Text("open menu") } In case it is meant to not work as tried above, is there an alternative way of achiving the intended reult? 回答1: NavigationLink should be inside NavigationView hierarchy. The Menu is outside navigation view, so put buttons inside menu which activate

问题 I've whittled my login page down to a single NavigationLink that leads to a List view as its destination. The problem, as you can see in the image below, is that instead of the nicely spaced title on the left, I get the huge space as shown on the right. Both views are the same, but the one on the right is the preview of the page as it was designed. The image on the left is the preview of the page after coming from the login screen. struct ContentView: View { var body: some View {

问题 I tried to do a list which have image and a navigation link inside. In iOS 14.1 everything work fine but after I update my iOS to 14.2, something break.

问题 I want to remove the NavigationTitle Space without removing the back button. I have already tried this: .navigationBarItems(trailing: NavigationLink(destination: Preferences(viewModel: viewModel).navigationBarHidden(true)) { Image(systemName: "gear") .font(.title2) } ) but that removes the back button as well. 回答1: Standard Back button cannot be shown without navigation bar, because it is navigation item, so part of navigation bar. I assume you just need transparent navigation bar. Here is

问题 I am having trouble hiding the navigation bar in case of multiple navigation views.
