多张工作表用于ForEach循环
问题开始：Int：String：“Baltimore”：“John”：“Mike”：DataArray(id：“Susan”：“Oliver”：False：isFavorite：Text(“\(data.id)”)提问开始:
我需要你的帮助，因为我不知道如何在我的ForEach循环中显示多张工作表。我想在每次单击我的ForEach项目时显示我的DetailView()。我相信NavigationLink可能会有所帮助，但我想坚持用一张纸来展示。请帮助我解决我的问题。提前谢谢。
import Foundation
import SwiftUI
struct DataArray: Identifiable {
let id: Int
let cities: String
let name1: String
let name2: String
let isBookMark: Bool
let isFavorite: Bool
}
public struct ListDataArray {
static let dot = [
DataArray(id: 1,
cities: "Baltimore"
name1: "John",
name2: "Mike",
isBookMark: False,
isFavorite: False),
DataArray(id: 2,
cities: "Frederick"),
name1: "Joe",
name2: "Swift",
isBookMark: False,
isFavorite: False),
DataArray(id: 3,
cities: "Catonsville"
name1: "Susan",
name2: "Oliver",
isBookMark: False,
isFavorite: False),
// There will be a lot of data
]
}
class Prospect: ObservableObject {
@Published var datas: [DataArray] = ListDataArray.dot
}
struct Home: View {
@EnvironmentObject var items: Prospect
var body: some View {
List {
ForEach(items.datas) { data in
Button {
//Action
} label: {
LazyHStack {
Text("\(data.id)")
.font(.title3)
Text(data.cities)
.font(.subheadline)
}
.padding()
}
.sheet(item: ) {
// Action for onDismiss
} content: { model in
DetailView(data: model)
}
}
.padding()
}
}
}
struct DetailView: View {
let data: DataArray
var body: some View {
VStack(spacing: 10) {
Text(data.cities)
Text(data.name1)
Text(data.name2)
}
.font(.body)
}
}
struct Home_Previews: PreviewProvider {
static var previews: some View {
Home()
.environmentObject(Prospect())
}
}您可以使用@State变量来跟踪选择了哪个项目，并将其传递给item参数的.sheet：
struct Home: View {
@EnvironmentObject var items: Prospect
@State private var sheetItem : DataArray?
var body: some View {
List {
ForEach(items.datas) { data in
Button {
sheetItem = data
} label: {
LazyHStack {
Text("\(data.id)")
.font(.title3)
Text(data.cities)
.font(.subheadline)
}
.padding()
}
}
.padding()
}
.sheet(item: $sheetItem) {
// Action for onDismiss
} content: { model in
DetailView(data: model)
}
}
