问题 I'd like to use a SwiftUI TextField and a SwiftUI List to render a "search box" above a list of items. Something roughly like the search box available in Safari's Help menu item...which provides a search box where you can always enter text while simultaneously browsing through the list of results using the up and down arrow keys. I've played with onMoveCommand, focusable, and adjustments to the "parent" NSWindow , but haven't found a clear and obvious way for the TextField to constantly

问题 I have a view with a List and depending on the item of the list I have clicked on, I need to open a different NavigationLink. I have a row model for one row of the List (I'm saying List even though I'm actually usually using a custom made element called Collection, which is a List with HStack and VStack together to emulate the UICollectionView ) In the row model view I can only specify one destination for the NavigationLink. A solution I can think of is getting the index of the item of the

问题 This question already has answers here : SwiftUI List color background (7 answers) Closed 7 months ago . I am trying on setting a view background color to black with the following code struct RuleList: View {[![enter image description here][1]][1] private var presenter: ConfigurationPresenter? @ObservedObject private var viewModel: RowListViewModel init(presenter: ConfigurationPresenter?, viewModel: RowListViewModel) { self.presenter = presenter self.viewModel = viewModel } var body: some

问题 I would like to have a SwiftUI view that shows many lines of text, with the following requirements: Works on both macOS and iOS. Shows a large number of strings (each string is backed by a separate model object). I can do arbitrary styling to the multiline text. Each string of text can be of arbitrary length, possibly spanning multiple lines and paragraphs. The maximum width of each string of text is fixed to the width of the container. Height is variable according to the actual length of

问题 I've seen several posts about this, but so far none of the solutions seem to be working for me. I'm trying to create an array of Identifiable items using ForEach -- with both a Text() and Toggle() view inside. The array is stored in a @Published property of an @ObservableObject . I'm currently looping through the indices to create the toggle bindings (as suggested in other posts). Everything appears to be working, until I try to delete a row. (Specifically the last row - which triggers a

问题 I have a simple List where each row is a Toggle with its Text and Text as a subtitle all in a VStack . All works fine until I start showing or hiding some rows. Somehow the switch of the Toggle view is misaligned and is placed over its title. This happens only on the device and not when running on the simulator. It happens with both XCode 13.3 and 13.4 beta on a device running iOS 13.3.1 The complete example is import SwiftUI struct ContentView: View { @State var showDetails = false @State

问题 Here is what I have based on this answer. The code currently allows the user to select a cell but I cannot distinguish which cell is selected or execute any code in response to the selection. In summary, how can I execute code based on the selected cell's name and execute on click. The cell currently highlights in blue where clicked, but I want to identify it and act accordingly based on that selection. Note: I am not looking to select the cell in editing mode. Also, how can I
