I'm trying to implement a horizontal table view in swift with the following functionalities:
Images listed in a horizontal manner
Horizontal scrolling left and right
See wireframe attached.
Can someone point me in the right direction? I tried digging into UICollectionView to implement this.
- SwiftUI
This question is asked a lot and there are so many answers out there for using CollectionView. But in SwiftUI you can use a horizontal ScrollView containing a Horizontal Stack like this:
struct CardView: View {
var body: some View {
Rectangle()
.foregroundColor(.gray)
.frame(width: 100, height: 80, alignment: .center)
.cornerRadius(8)
}
}
struct ContentView: View {
var body: some View {
VStack {
HStack {
Text("Categories")
Spacer()
Button(action: {}) { Text("More") }
}.padding(16)
ScrollView(.horizontal) {
HStack(spacing: 16) {
ForEach(0...15, id: \.self) { _ in
CardView()
}
}.padding(16)
}
}
}
}
- Result
Note that you can use this inside a UITableViewCell later this month when SwiftUI officially released by Apple.

If you put the code in VStack and add another View to it, then the container rises

I looked it up with a hierarchy view, and noticed that a UIInputSetHostView is created with a height of 216

Currently, I am studying SwiftUI and making UI that is displayed in the view when registering hashtags.
But I don't know what to do with the logic of creating and inserting a new HStack when it's out of screen size inside the VStack.
I've searched several times, but I couldn't find any helpful words or keywords.
I would appreciate it if you could help me by knowing the answer.
The image above is an example.
I want to create a new HStack and put it in the VStack when the width exceeds the horizontal size of the device while inserting a text item into the HStack.
struct HashTagView: View {
var hashTagArray: [String] = ["#Lorem", "#Ipsum", "#dolor", "#sit", "#amet", "#consectetur", "#adipiscing", "#elit", "#Nam", "#semper", "#sit", "#amet", "#ut", "#eleifend", "#Cras"]
var body: some View {
VStack(spacing: 5) {
ForEach(hashTagArray, id:\.self) { tag in
Text(tag)
}
}
.padding()
.border(Color.blue)
.frame(width: UIScreen.main.bounds.size.width)
}
}
this is my code.
You should use a LazyVgrid with an adaptive layout here:
I removed some entries from your array because if you use it with id: \.self you should ensure that every entry is unique.
Documentation
struct HashTagView: View {
var hashTagArray: [String] = ["#Lorem", "#Ipsum", "#dolor", "#consectetur", "#adipiscing", "#elit", "#Nam", "#semper", "#sit", "#amet", "#ut", "#eleifend", "#Cras"]
private var gridItemLayout = [GridItem(.adaptive(minimum: 100))]
var body: some View {
ScrollView{
LazyVGrid(columns: gridItemLayout , spacing: 5) {
ForEach(hashTagArray, id:\.self) { tag in
Text(tag)
}
}
.padding()
.border(Color.blue)
}
.frame(width: UIScreen.main.bounds.size.width)
}
}
I am trying to set the content Text("Test.....") inside the scroll view to the top. Without using .frame (maxHeight: 150) and the like. I just need to kick it up under Text ("123")) but nothing comes out. And while scrolling in all directions should work. This is just an example to understand how to do it technically. Guys who can help!
import SwiftUI
struct MainView: View {
var body: some View {
NavigationView {
content
}
.padding()
}
}
private extension MainView {
var content: some View {
VStack {
ZStack(alignment: .topLeading) {
ScrollView([.vertical, .horizontal]) {
Text("TestTestTestTestTestTestTestTestTestTestTest")// set to top in content
.frame(height: 100)
.background(Color.green)
//.position(y: 0)
}
Text("123")
}
.background(Color.blue)
}
}
}
You can use .offset() for that
.offset(y: -230)
or
.offset(y: UIScreen.main.bounds.height * -0.28) // for responsive
Is it possible to create a custom horizontal indicator that has empty and filled circles to show how many images there are and the current position?
The below attempt uses a lazyHStack and OnAppear but, judging from the console output, it doesn't work properly since scrolling back and forth doesn't recall the onAppear consistently.
import SwiftUI
struct ContentView: View {
let horizontalScrollItems = ["wind", "hare.fill", "tortoise.fill", "rosette" ]
var body: some View {
GeometryReader { geometry in
ScrollView(.horizontal, showsIndicators: false) {
LazyHStack {
ForEach(horizontalScrollItems, id: \.self) { symbol in
Image(systemName: symbol)
.font(.system(size: 200))
.frame(width: geometry.size.width)
.onAppear(){print("\(symbol)")}
}
}
}
}
}
}
This is the desired indicator. I'm just not sure how to properly fill and empty each circle as the user scrolls back and forth. Appreciate the help!
You can get the desired result using TabView() and PageTabViewStyle()
Note : This will work from SwiftUI 2.0
Here is the code :
struct ContentView: View {
let horizontalScrollItems = ["wind", "hare.fill", "tortoise.fill", "rosette" ]
var body: some View {
GeometryReader { geometry in
TabView(){
ForEach(horizontalScrollItems, id: \.self) { symbol in
Image(systemName: symbol)
.font(.system(size: 200))
.frame(width: geometry.size.width)
}
}
.tabViewStyle(PageTabViewStyle())
.indexViewStyle(PageIndexViewStyle(backgroundDisplayMode: .always))
}
}
}

I'm trying to re-create UI of my current app using SwiftUI. And it is way more difficult than I initially though.
I wanted to achieve card-like cells with some background behind them. I found that List doesn't support that, at least yet. List is so limited - it doesn't allow you to remove cell separator.
So I moved to ForEach inside ScrollView. I guess that isn't something which should be used in production for long tables but that should work for now. The problem I have is that ForeEach view doesn't take all the width ScrollView provides. I can set .frame(...) modifier but that will require hardcoding width which I definitely don't want to do.
Any ideas how to force VStack take full width of the ScrollView? I tried to use ForeEach without VStack and it has the same issue. It seems like ScrollView (parent view) "tells" its child view (VStack) that its frame is less that actual ScrollView's frame. And based on that information child views build their layout and sizes.
Here is my current result:
And here is the code:
struct LandmarkList : View {
var body: some View {
NavigationView {
ScrollView() {
VStack {
Spacer().frame(height: 160)
ForEach(landmarkData) { landmark in
LandmarkRow(landmark: landmark).padding([.leading, .trailing], 16)
}
}.scaledToFill()
.background(Color.pink)
}
.background(Color.yellow)
.edgesIgnoringSafeArea(.all)
.navigationBarTitle(Text("Landmarks"))
}
}
}
struct LandmarkRow : View {
var landmark: Landmark
var body: some View {
HStack {
VStack(alignment: .leading) {
Text(landmark.name).font(.title)
Text("Subtitle")
.font(.callout)
.color(.gray)
}
Spacer()
Text("5 mi")
.font(.largeTitle)
}.frame(height: 80)
.padding()
.background(Color.white)
.cornerRadius(16)
.clipped()
.shadow(radius: 2)
}
}
I've got the same issue, the only way I have found so far is to fix the ScrollView and the content view width, so that every subview you add inside the content view will be centered.
I created a simple wrapper that take the width as init parameter
struct CenteredList<Data: RandomAccessCollection, Content: View>: View where Data.Element: Identifiable {
public private(set) var width: Length
private var data: Data
private var contentBuilder: (Data.Element.IdentifiedValue) -> Content
init(
width: Length = UIScreen.main.bounds.width,
data: Data,
#ViewBuilder content: #escaping (Data.Element.IdentifiedValue) -> Content)
{
self.width = width
self.data = data
self.contentBuilder = content
}
var body: some View {
ScrollView {
VStack {
ForEach(data) { item in
return self.contentBuilder(item)
}.frame(width: width)
}
.frame(width: width)
}
.frame(width: width)
}
}
By default it takes the screen width (UIScreen.main.bounds.width).
It works just like a List view:
var body: some View {
TileList(data: 0...3) { index in
HStack {
Text("Hello world")
Text("#\(index)")
}
}
}
Its possible that the answer to this might just be wrapping your scrollView inside of a GeometryReader
