I ask this question before, it was answered but it is not work for many data, like when I click the any list items, all details pass name of "david", I want to pass data of user which I clicked, where I missed here?
struct ImageModel: Identifiable, Hashable {
var id = UUID().uuidString
var name: String
}
var datas = [
ImageModel(name: "davis"),
ImageModel(name: "carry"),
ImageModel(name: "maria"),
]
struct ImageRowView: View {
var data: ImageModel
var body: some View {
NavigationLink(destination: ImageDetailsView(data: ImageModel)){
HStack{}
}}}
struct ImageDetailsView: View {
var body: some View {
ImageDetails(data: ImageModel(name: "davis"))
}
}
struct ImageDetailsView_Previews: PreviewProvider {
static var previews: some View {
ImageDetailsView()
}
}
struct ImageDetails : View {
var data: ImageModel
var body: some View{
VStack{
Text(data.name)
}
}
The reason the image detail view always shows davis is because your image details view always uses the davis image model.
struct ImageDetailsView: View {
var body: some View {
ImageDetails(data: ImageModel(name: "davis"))
}
}
You need to add a property to the image details view that stores the image model to display.
@Binding var imageModel: ImageModel
Pass the property to ImageDetails.
ImageDetails(data: $imageModel)
I don't see any list code, but you have to create a @State property in the view that has the list to store the selected list item.
@State private var selectedImage: ImageModel? = nil
Your list code should contain a navigation link to the details view.
NavigationLink(destination: ImageDetailsView(imageModel: $selectedImage))
Now the details view would show the selected image. But your code has a problem. In both ImageRowView and ImageDetails, you have the following property:
var data: ImageModel
SwiftUI views do not live long. When a change occurs to a view, SwiftUI creates a brand new view. When SwiftUI creates a new view, you will lose the contents of the data variable. In ImageRowView, you should declare a @State property like the selectedImage property I declared earlier. When you use @State, SwiftUI will keep the property when it creates a new view. In ImageDetails you should declare a @Binding property, like the imageModel binding I declared earlier, so it will show the selected image model.
I can't guarantee that everything will work now, but it should get you towards a solution. If you need a working example, the GitHub project at the following URL provides an example of handling list selection and working with @State and @Binding:
