所以我在页面视图样式中的 TabView 中嵌入了一个 NavigationView。在第一次加载时,NavigationView 将以低于其应有位置的标题开始。一旦我重新加载视图,通过转到不同的选项卡,它会正确重置其自身。有没有办法解决这个问题,让它从正确的位置开始?我制作了一个 GIF 来更好地说明这个问题:
这是我的代码:
struct ContentView: View {
var body: some View {
TabView {
SettingsView()
BlankView(color: .green)
BlankView(color: .blue)
BlankView(color: .red)
}
.tabViewStyle(PageTabViewStyle(indexDisplayMode: .never))
}
}
struct SettingsView: View {
var body: some View {
NavigationView {
List {
Section(header: Text("General")) {
NavigationLink(destination: SettingsItem(title: "1")) {
Text("1")
}
NavigationLink(destination: SettingsItem(title: "2")) {
Text("2")
}
NavigationLink(destination: SettingsItem(title: "3")) {
Text("3")
}
NavigationLink(destination: SettingsItem(title: "4")) {
Text("4")
}
}
}
.listStyle(InsetGroupedListStyle())
.navigationTitle("Settings")
}
.navigationViewStyle(StackNavigationViewStyle())
}
}
struct SettingsItem: View {
@State var title = "Title"
var body: some View {
NavigationView {
List {
}
}
.navigationTitle(title)
}
}
struct BlankView: View {
let color: Color
var body: some View {
ZStack{
color
Text("Blank View")
.padding()
}
.border(Color.black, width: 8)
}
}
