我正在构建一个食谱应用程序,其构建过程如下:
首先,我在一个单独的结构中创建了一个基本视图,并以Image
作为背景,并在顶部显示了一些文本。然后我创建了一些水平ScrollViews
,在其中嵌入了这些基本视图的视图。
我想要的是,当用户点击其中一个视图时,他们会根据选择进入详细信息屏幕。为此,我将视图的所有代码以及图像和文本嵌入navigationLink
中。但是当我在模拟器中运行该应用程序并按其中一个视图时,没有任何反应。
这是带有文本和图像的视图的代码:
NavigationLink(destination: DetailView(title: titleText)) {
ZStack {
Image(foodImageName)
.resizable()
.renderingMode(.original)
VStack {
Text(titleText)
.foregroundColor(Color.init(hex: "AAAAAA"))
.font(.system(size: 30, weight: .semibold))
Spacer()
}
}
.frame(width: 189, height: 194)
.cornerRadius(15)
.shadow(color: Color.init(hex:"000000"), radius: 7,x: 7, y: 7)
}
这是主视图的代码:
struct ContentView: View {
private var spacing: CGFloat = 20
var body: some View {
NavigationView {
VStack {
Text("First Course")
.frame(height: 36)
.font(.system(size: 25, weight: .semibold))
ScrollView (Axis.Set.horizontal, showsIndicators: false){
HStack{
MenuTopicView(titleText: "Soup", foodImageName: "Soup")
MenuTopicView(titleText: "Fish", foodImageName: "Soup")
}
}.frame(height: 200)
Text("Main Course")
.frame(height: 36)
.font(.system(size: 25, weight: .semibold))
ScrollView(Axis.Set.horizontal) {
HStack {
MenuTopicView(titleText: "Steak", foodImageName: "Soup")
MenuTopicView(titleText: "Chicken", foodImageName: "Soup")
}
}
Text("Dessert")
.frame(height: 36)
.font(.system(size: 25, weight: .semibold))
ScrollView(Axis.Set.horizontal) {
HStack {
MenuTopicView(titleText: "Ice cream", foodImageName: "Soup")
MenuTopicView(titleText: "Pancakes", foodImageName: "Soup")
}
}
}
.navigationBarTitle("Recipes")
}
}
}
有人对我做错了什么建议吗?
谢谢!
最佳答案
您应该将每个MenuTopicView
包裹在其单独的NavigationLink中,然后将其添加到ContentView
中,以便它们起作用,因为它们都有各自的目的地。像这样:
ScrollView (Axis.Set.horizontal, showsIndicators: false){
HStack{
NavigationLink(destination: DetailView("Soup")) {
MenuTopicView(titleText: "Soup", foodImageName: "Soup")
}
NavigationLink(destination: DetailView("Fish")) {
MenuTopicView(titleText: "Fish", foodImageName: "Soup")
}
}
}.frame(height: 200)
我建议创建更通用的视图,这样您就不必重复自己了。像这样:
struct ContentView: View {
let sections: [MenuSection]
private var spacing: CGFloat = 20
var body: some View {
NavigationView {
VStack {
ForEach(sections, id: \.self) { section in
MenuSectionView(sectionTitle: section.title, items: section.items)
}
}
.navigationBarTitle("Recipes")
}
}
}
struct MenuSectionView: View {
let sectionTitle: String
let items: [MenuItem]
var body: some View {
VStack {
Text(sectionTitle)
.frame(height: 36)
.font(.system(size: 25, weight: .semibold))
ScrollView (Axis.Set.horizontal, showsIndicators: false) {
HStack {
ForEach(items, id: \.self) { item in
NavigationLink(destination: RecipeView(recipeName: item.title)) {
MenuTopicView(titleText: item.title, foodImageName: item.image)
}
}
}
}.frame(height: 200)
}
}
}
