我目前正在尝试按照教程处理 SwiftUI,但不知何故我无法解决一个问题:
我创建了另一个 View ,即我的 HomeView.swift - 该文件包含以下代码:
import SwiftUI
struct Home: View {
var menu = menuData
@State var show = false
var body: some View {
ZStack {
ZStack(alignment: .topLeading) {
Button(action: { self.show.toggle() }) {
HStack {
Spacer()
Image(systemName: "list.dash")
.foregroundColor(Color("primary"))
}
.padding(.trailing, 20)
.frame(width: 90, height: 60)
.background(Color.white)
.cornerRadius(30)
.shadow(color: Color("shadow"), radius: 10, x: 0, y: 10)
}
Spacer()
}
ZStack(alignment: .topTrailing) {
Button(action: { self.show.toggle() }) {
HStack {
Spacer()
Image(systemName: "map.fill")
.foregroundColor(Color("primary"))
}
.padding(.trailing, 20)
.frame(width: 44, height: 44)
.background(Color.white)
.cornerRadius(30)
.shadow(color: Color("shadow"), radius: 10, x: 0, y: 10)
}
Spacer()
}
MenuView(show: $show)
}
}
}
struct Home_Previews: PreviewProvider {
static var previews: some View {
Home()
}
}
struct MenuRow: View {
var text: String?
var image: String?
var body: some View {
HStack {
Image(systemName: image ?? "")
.foregroundColor(Color("third"))
.frame(width: 32, height: 32, alignment: .trailing)
Text(text ?? "")
.font(Font.custom("Helvetica Now Display Bold", size: 15))
.foregroundColor(Color("primary"))
Spacer()
}
}
}
struct Menu: Identifiable {
var id = UUID()
var title: String
var icon: String
}
let menuData = [
Menu(title: "My Account", icon: "person.crop.circle.fill"),
Menu(title: "Reservations", icon: "house.fill"),
Menu(title: "Sign Out", icon: "arrow.uturn.down")
]
struct MenuView: View {
var menu = menuData
@Binding var show: Bool
var body: some View {
VStack(alignment: .leading, spacing: 20) {
ForEach(menu) { item in
MenuRow(text: item.title, image: item.icon)
}
Spacer()
}
.padding(.top, 20)
.padding(30)
.frame(minWidth: 0, maxWidth: .infinity)
.background(Color.white)
.cornerRadius(30)
.padding(.trailing, 60)
.shadow(radius: 20)
.rotation3DEffect(Angle(degrees: show ? 0 : 60), axis: (x: 0, y: 10, z: 0))
.animation(.default)
.offset(x: show ? 0 : -UIScreen.main.bounds.width)
.onTapGesture {
self.show.toggle()
}
}
}
如您所见,一开始,在我的 Home 结构中,我尝试对齐两个 ZStack - 一个
.topLeading
和一个 .topTrailing
。 阅读文档,这应该改变它的位置,但不知何故它没有。两个堆栈都保持居中。 顺便说一句,我还没有特别接触 ContenView.swift 呢。
最佳答案
struct Home: View {
var menu = menuData
@State var show = false
var body: some View {
ZStack {
VStack {
HStack {
Button(action: { self.show.toggle() }) {
HStack {
Spacer()
Image(systemName: "list.dash")
.foregroundColor(Color("primary"))
}
.padding(.trailing, 20)
.frame(width: 90, height: 60)
.background(Color.white)
.cornerRadius(30)
.shadow(color: Color("shadow"), radius: 10, x: 0, y: 10)
}
Spacer()
Button(action: { self.show.toggle() }) {
HStack {
Spacer()
Image(systemName: "map.fill")
.foregroundColor(Color("primary"))
}
.padding(.trailing, 20)
.frame(width: 44, height: 44)
.background(Color.white)
.cornerRadius(30)
.shadow(color: Color("shadow"), radius: 10, x: 0, y: 10)
}
}
Spacer()
}
MenuView(show: $show)
}
}
}
这是您要找的布局吗?使用 VStack 和 HStack,您可以将 View 与顶部和两端对齐
关于ios - SwiftUI 不会对齐 ZStack,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/58868698/
