navigationbar

问题 I recently updated my Xcode to 11.4. When I run the app on the device, i've noticed that all my navigations item's titles gone fully black when being set from storyboard. You can't change neither from code, the following line of code doesn't work anymore self.navigationController?.navigationBar.titleTextAttributes = [.foregroundColor: UIColor.white] I only make it work using some iOS 13 stuffs UINavigationBarAppearance @available(iOS 13.0, *) private func setupNavigationBar() { let app =

问题 I need to have a close button (in this particular case) on the left of Navigation Bar , as below. I need it only for popups, so there is no potential issues with other elements/navigations. There are a few suggestions in Google regarding this, but I saw only iOS examples (and this is not a big thing to handle in iOS custom renderer ), but no hints how to handle it ( easily ) with Android . Just to be clear, it need it for Xamarin.Forms defining similar to this (or codebehind): <ContentPage

问题 I've modified the title font, color and background of navigationBar using UINavigationBar.appearance().titleTextAttributes and UINavigationBar.appearance().backgroundColor . However I can't find any attribute to set the navigationBarTitle alignment to right (trailing). Additionally, I've even tried .navigationBarTitle(Text("Title").multilineTextAlignment(.leading)) modifier, but SwiftUI does not accept it. Any solution will be appreciated. 回答1: It is possible to change any view right-to-left

To get rid of it, just set it to an empty image: navigationController.navigationBar.shadowImage = UIImage() Note: You must set it to an empty UIImage() ; nil won't work for some reason. 回答2: You need to set a custom shadow image to show instead of the default one. Note: a custom background image must also be set. navController.navigationBar
