I'm trying to implement the following css code in SwiftUI
background: #FFFFFF;
box-shadow: 0px 10px 20px rgba(223, 227, 240, 0.2);
border-radius: 27.5px;
It should look like this (barely visible shadow below the button):
Here's the code i'm currently experimenting with:
import SwiftUI
struct RegisterView: View {
var body: some View {
VStack(spacing: 0) {
HStack(alignment: .top) {
Text("Register")
.font(.custom("NotoSans-Regular", size: 24))
.fontWeight(.bold)
.foregroundColor(Color.tertiaryTitleColor)
}
.frame(width: 299, height: 39)
.padding(.top, 78)
HStack {
BroviderButton(imageName: "googleLogo")
BroviderButton(imageName: "facebookLogo")
}
.padding(.top, 47)
Spacer()
}
.frame(maxHeight: .infinity)
.frame(maxWidth: .infinity)
.background(Color.loginBackgroundColor)
.ignoresSafeArea()
}
}
struct RegisterView_Previews: PreviewProvider {
static var previews: some View {
RegisterView()
}
}
struct BroviderButton: View {
var imageName: String
var body: some View {
ZStack {
RoundedRectangle(cornerRadius: 27.5)
.stroke(Color.dropShadowColor,lineWidth: 1)
.frame(width: 133, height: 56, alignment: .center)
.shadow(color: .black, radius: 2, x: 1, y: 2)
VStack {
VStack {
Image(imageName)
.resizable()
.scaledToFit()
}
.frame(height: 28, alignment: .center)
}
.frame(width: 133, height: 56, alignment: .center)
.foregroundColor(.blue)
.background(Color.loginButtonBackgroundColor)
.cornerRadius(27.5)
.opacity(1)
}
}
}
And here's how it looks like atm:
I don't understand how to translate x:10 & y:20 to SwiftUI code and also can't find the way to blur the shadow (20%). Any ideas are welcome.
Also can't figure out why that RoundedRectangle stays visible after i put VStack on top of it.. I was thinking it will hide everything but the shadow below the button.
As far as I see there are two issues here to be fixed (although of course I don't have your colors and images):
ZStack {
RoundedRectangle(cornerRadius: 27.5)
.fill(Color.dropShadowColor) // << here fill, not stroke !!
.frame(width: 133, height: 56, alignment: .center)
.shadow(color: .black, radius: 2, x: 0, y: 2) // << no offset by x
VStack {
VStack {
Image(imageName)
.resizable()
.scaledToFit()
}
.frame(height: 28, alignment: .center)
}
.frame(width: 133, height: 56, alignment: .center)
.foregroundColor(.blue)
.background(Color.loginButtonBackgroundColor) // << should be opaque color !!
.cornerRadius(27.5)
.opacity(1)
}

I want to show part of next item in tabview as following design
I managed to show one item per page but I couldn't show part of next one. Here's my code
GeometryReader { proxy in
TabView(selection: $viewModel.selectedTabIndex) {
ForEach(self.viewModel.data?.perspective ?? []) { item in
HStack(spacing: 20) {
Image("icon")
.resizable()
.scaledToFit()
.frame(width: 24, height: 24, alignment: .center)
Text(item.name)
.font(.system(size: 16, weight: .medium))
.foregroundColor(Color.white)
.tag(item.id)
Spacer()
}
.frame(width: proxy.size.width - 70, height: 40, alignment: .center)
.padding(.horizontal)
.background(.red)
.cornerRadius(5)
}
}
.tabViewStyle(.page(indexDisplayMode: .never))
}
.frame(height: 40, alignment: .center)
I am trying to build a List that I want to look like a timeline.
Each cell will represent a milestone.
Down the left hand side of the table, I want the cells to be 'connected', by a line (the timeline).
I have tried various things to get it to display as I want but I have settled with basic geometric shapes , i.e Circle() and Rectangle().
This is sample code to highlight the problem:
import SwiftUI
struct ContentView: View {
var body: some View {
let roles: [String] = ["CEO", "CFO", "Managing Director and Chairman of the supervisory board", "Systems Analyst", "Supply Chain Expert"]
NavigationView{
VStack{
List {
ForEach(0..<5) { toto in
NavigationLink(
destination: dummyView()
) {
HStack(alignment: .top, spacing: 0) {
VStack(alignment: .center, spacing: 0){
Rectangle()
.frame(width: 1, height: 30, alignment: .center)
Circle()
.frame(width: 10, height: 10)
Rectangle()
.frame(width: 1, height: 20, alignment: .center)
Circle()
.frame(width: 30, height: 30)
.overlay(
Image(systemName: "gear")
.foregroundColor(.gray)
.font(.system(size: 30, weight: .light , design: .rounded))
.frame(width: 30, height: 30)
)
//THIS IS THE RECTANGLE OBJECT FOR WHICH I WANT THE HEIGHT TO BE VARIABLE
Rectangle()
.frame(width: 1, height: 40, alignment: .center)
.foregroundColor(.green)
}
.frame(width: 32, height: 80, alignment: .center)
.foregroundColor(.green)
VStack(alignment: .leading, spacing: 0, content: {
Text("Dummy operation text that will be in the top of the cell")
.font(.subheadline)
.multilineTextAlignment(.leading)
.lineLimit(1)
Label {
Text("March 6, 2021")
.font(.caption2)
} icon: {
Image(systemName: "calendar.badge.clock")
}
HStack{
HStack{
Image(systemName: "flag.fill")
Text("In Progress")
.font(.system(size: 12))
}
.padding(.horizontal, 4)
.padding(.vertical, 3)
.foregroundColor(.blue)
.background(Color.white)
.cornerRadius(5, antialiased: true)
HStack{
Image(systemName: "person.fill")
Text(roles[toto])
.font(.system(size: 12))
}
.padding(.horizontal, 4)
.padding(.vertical, 3)
.foregroundColor(.green)
.background(Color.white)
.cornerRadius(5, antialiased: true)
HStack{
Image(systemName: "deskclock")
Text("in 2 Months")
.font(.system(size: 12))
}
.padding(.horizontal, 4)
.padding(.vertical, 3)
.foregroundColor(.red
)
.background(
Color.white
)
.cornerRadius(5, antialiased: true)
}
})
}.listRowInsets(.init(top: 0, leading: 0, bottom: 0, trailing: 0))
}
}
}
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
struct dummyView: View {
var body: some View {
Text("Hello, World!")
}
}
struct dummyView_Previews: PreviewProvider {
static var previews: some View {
dummyView()
}
}
but as you can see in the enclosed picture, there are unwanted gaps
So other content in the cell is making the height of the entire cell 'unpredictable' and break the line.
Is there a way to determine the height of the cell and extend the dimensions of the Rectangle, so that it extends to the full height of the cell?
Is there a better approach you recommend for trying to build such a timeline ?
PS: I have tried playing around with .frame and .infinity but that does work.
Many thanks.
Why not just draw the line based on the size of the row. See Creating custom paths with SwiftUI. Remember, everything is a view.
First, you need to decompose what you are doing into subviews. You have too many moving parts in one view to get it correct. Also, I would avoid setting specific padding amounts as that will mess you up when you change devices. You want a simple, smart view that is generic enough to handle different devices.
I would have a row view that has a geometry reader so it knows its own height. You could then draw the line so that it spanned the full height of the row, regardless of the height. Something along the lines of this:
struct ListRow: View {
var body: some View {
GeometryReader { geometry in
ZStack {
HStack {
Spacer()
Text("Hello, World!")
Spacer()
}
VerticalLine(geometry: geometry)
}
}
}
}
and
struct VerticalLine: View {
let geometry: GeometryProxy
var body: some View {
Path { path in
path.move(to: CGPoint(x: 20, y: -30))
path.addLine(to: CGPoint(x: 20, y: geometry.size.height+30))
}
.stroke(Color.green, lineWidth: 4)
}
}
I have a horizontal ScrollView and would like to provide a function that when the first element is not visible anymore an arrow should appear to signalize that there are some other elements.
I've tried the DragGesture() to read the translation.width but it seems to be buggy in combination with the ScrollView.
So I'm looking for a way to detect whether the ScrollView was scrolled and how far. Is there any way?
private let gridItems = [GridItem(.flexible())]
ScrollView(.horizontal, showsIndicators: false) {
HStack{
LazyHGrid(rows: gridItems){
ForEach(viewModel.imageOptions, id: \.self){ image in
ZStack {
Image(image)
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 60, height: 60)
.background(Color.white)
.clipShape(Circle())
.background(
Circle()
.clipShape(Circle())
.shadow(color: Color.black.opacity(0.4), radius: 3, x: 5.0, y: 5.0)
)
.onTapGesture {
print("selected")
}
.padding(15)
Circle()
.strokeBorder(Color.orange, lineWidth: 5)
.frame(width: 70, height: 70)
}
}
}
}
}
}
I can't get rid of this "leading" padding inside one of my VStacks.
I set alignment to "leading" for its parent VStack but it still shows some spacing on the left (for the text and red rounded rectangle). They were supposed to be placed on the left next to the blue edge on screenshot.
Any ideas on why this padding appears there?
Here's the code:
import SwiftUI
struct RegisterView: View {
var body: some View {
VStack(spacing: 0) {
HStack(alignment: .top) {
Text("Register")
.font(.custom("NotoSans-Regular", size: 24))
.fontWeight(.bold)
.foregroundColor(Color.tertiaryTitleColor)
}
.frame(width: 299, height: 39)
.padding(.top, 78)
HStack(spacing: 13) {
BroviderButton(imageName: "googleLogo")
BroviderButton(imageName: "facebookLogo")
}
.padding(.top, 47)
VStack(alignment: .leading, spacing: 0) {
Text("Register with E-mail")
.font(.custom("NotoSans-Regular", size: 16))
RoundedRectangle(cornerRadius: 25)
.fill(Color.red)
.frame(width: 40, height: 20)
}
.frame(width: 279)
.padding(.top, 61)
Spacer()
}
.frame(maxHeight: /*#START_MENU_TOKEN#*/.infinity/*#END_MENU_TOKEN#*/)
.frame(maxWidth: /*#START_MENU_TOKEN#*/.infinity/*#END_MENU_TOKEN#*/)
.background(Color.loginBackgroundColor)
.ignoresSafeArea()
}
}
struct RegisterView_Previews: PreviewProvider {
static var previews: some View {
RegisterView()
}
}
struct BroviderButton: View {
var imageName: String
var body: some View {
ZStack {
RoundedRectangle(cornerRadius: 27.5)
.frame(width: 133, height: 56, alignment: /*#START_MENU_TOKEN#*/.center/*#END_MENU_TOKEN#*/)
.shadow(color: Color.dropShadowColor, radius: 1, x: 10, y: 20)
.offset(y: 15)
.opacity(0.2)
.blur(radius: 20)
.opacity(0.2)
VStack {
VStack {
Image(imageName)
.resizable()
.scaledToFit()
}
.frame(height: 28, alignment: /*#START_MENU_TOKEN#*/.center/*#END_MENU_TOKEN#*/)
}
.frame(width: 133, height: 56, alignment: /*#START_MENU_TOKEN#*/.center/*#END_MENU_TOKEN#*/)
.foregroundColor(/*#START_MENU_TOKEN#*/.blue/*#END_MENU_TOKEN#*/)
.background(Color.loginBackgroundColor)
.cornerRadius(27.5)
.opacity(1)
}
}
}
You need also apply alignment to frame of container, like
VStack(alignment: .leading, spacing: 0) {
Text("Register with E-mail")
.font(.custom("NotoSans-Regular", size: 16))
RoundedRectangle(cornerRadius: 25)
.fill(Color.red)
.frame(width: 40, height: 20)
}
.frame(width: 279) // << do you really need this? why?
.frame(maxWidth: .infinity, alignment: .leading) // << here !!
.padding(.top, 61)
When .relativeSize is called on HStack{}, the borders do not come closer. Indicative of dimensions not being adjusted.
I've already tried rearranging the sequence of method calls on HStack, such that .relativeSize is called before and after .frame and .border
struct ContentView : View {
var body: some View{
VStack(alignment: .center, spacing: 1){
//Top box holding a rectangle
HStack{
Text("Test")
}
.frame(width: 355, height: 99, alignment: .center)
.relativeSize(width: 0.95, height: 0.95)
.border(Color.blue, width: 2)
//Bottom box holding 3 recangles
HStack{
Text("Test")
}
.frame(width: 355, height: 47, alignment: .center)
.border(Color.red, width: 1)
}
.frame(width: 355, height: 148, alignment: .center)
.border(Color.black, width: 1)
//body paren
}
}
Simply add a Spacer() before and after the text, and remove the .frame() modifier. This way the HStack will expand laterally as much as 0.95 the size of the containing VStack. Is this what you want?
struct ContentView : View {
var body: some View{
VStack(alignment: .center, spacing: 1){
//Top box holding a rectangle
HStack{
Spacer()
Text("Test")
Spacer()
}
.relativeSize(width: 0.95, height: 0.95)
.border(Color.blue, width: 2)
//Bottom box holding 3 recangles
HStack{
Text("Test")
}
.frame(width: 355, height: 47, alignment: .center)
.border(Color.red, width: 1)
}
.frame(width: 355, height: 148, alignment: .center)
.border(Color.black, width: 1)
//body paren
}
}
