tabview

问题 This code appears to work very well on the canvas preview, but on my real device, sometimes the background color does not update. When switching tabs, the color from the former view remains although the rest of the view is fine. What gives? Here is the main tab view: import SwiftUI struct ContentView: View { @EnvironmentObject var isModalVisible: CustomModal @ObservedObject var modal = CustomModal() var body: some View { ZStack { TabView { ZStack { Color.pink.opacity(0.2) Button(action: {

问题 I am trying to see if I can make the color of the bottom tabview change depending on which tab item is selected. Currently I can make the tabview bar clear with the below code in the init. let tabBar = UITabBar.appearance() init() { tabBar.barTintColor = UIColor.clear tabBar.backgroundImage = UIImage() tabBar.shadowImage = UIImage() } ... TabView(selection: $selectedTab) { FirstView() .tabItem{ Text("First") } SecondView() .tabItem{ Text("Second") } } .onAppear{ setTabViewBackground() } func

问题 I fail to style the text of a PrimeNG TabView. Here's the Stackblitz showing the problem. What am I missing? 回答1: One way to solve your problem is to override PrimeNG class concerning tabview title : ui-tabview-title . So something like .ui-tabview-title { color: red; } should do the trick. Be sure to call that CSS after PrimeNG one. Edit You can apply CSS on first tab header with :first-child property : ul.ui-tabview-nav li:first-child span { color: red; } See working StackBlitz. 来源： https:/

问题 I have a TabView thats using the swiftUI 2.0 PageTabViewStyle. Is there any way to disable the swipe to change pages? I have a search bar in my first tab view, but if a user is typing, I don't want to give the ability to change they are on, I basically want it to be locked on to that screen until said function is done. Here's a gif showing the difference, I'm looking to disable tab changing when it's full screen in the gif. https://imgur.com/GrqcGCI 回答1: Try something like the following

问题 I came across a weird Issue in SwiftUI. I created a simple View that only holds a Button and a TabView that uses the PageViewStyle. It seems that the TabView does not update it's content correctly depending on the State of the Variable. It seems that the content gets updated somehow but the View wont be updated how I would expect Here is the Code of my View: struct ContentView: View { @State var numberOfPages: Int = 0 @State var selectedIndex = 0 var body: some View { VStack { Text("Tap Me")
