Button overlay is showing over Button Text, SwiftUI - ios

My Button requires a couple overlays to get the style it needs (stroke, shadow etc).
However these overlays then go over the Button text.
View:
struct ProfileTest: View {
var body: some View {
Button(action: {
}){
HStack {
Text("OFFLINE")
.font(.custom("Seravek-Bold", size: 25))
.fontWeight(.bold)
.foregroundColor(Color.blue)
}
}.padding(EdgeInsets(top: 12, leading: 15, bottom: 12, trailing: 15))
.cornerRadius(50)
.overlay(
RoundedRectangle(cornerRadius: 50)
.stroke(Color.black, lineWidth: 1)
)
.overlay(
RoundedRectangle(cornerRadius: 50)
.fill(Color.red)
.shadow(color: Color.black.opacity(1), radius: 1)
)
.opacity(0.7)
.padding(.bottom, 100)
.padding(.bottom, 20)
}
}
How can I adjust my view so that the blue text shows above the background?

You can use a custom ButtonStyle.
Create your own shape and add .overlay(configuration.label) on top of it:
struct CustomButtonStyle: ButtonStyle {
func makeBody(configuration: Self.Configuration) -> some View {
configuration.label
.hidden()
.padding(EdgeInsets(top: 12, leading: 15, bottom: 12, trailing: 15))
.cornerRadius(50)
.overlay(
RoundedRectangle(cornerRadius: 50)
.stroke(Color.black, lineWidth: 1)
)
.overlay(
RoundedRectangle(cornerRadius: 50)
.fill(Color.red)
.shadow(color: Color.black.opacity(1), radius: 1)
)
.opacity(0.7)
.overlay(configuration.label)
.padding(.bottom, 100)
.padding(.bottom, 20)
}
}
You can also use configuration.isPressed to customise your label behaviour on button press.
Apply it to your Button:
struct ContentView: View {
var body: some View {
Button(action: {}) {
HStack {
Text("OFFLINE")
.font(.custom("Seravek-Bold", size: 25))
.fontWeight(.bold)
.foregroundColor(Color.blue)
}
}
.buttonStyle(CustomButtonStyle())
}
}

How to: Layout in Swift UI using ZStack, VStack, HStack

I am trying to achieve this layout https://gyazo.com/9714f8f1bff98edb3365338563b28fe8 in Swift UI using V and H Stacks. So far I have achieved this https://gyazo.com/fec9ae229e59a41add6542c9a8ad31af. I haven't found the right approach just yet on what to do here for more manipulation. What properties would help me achieve the desired layout?
Update! Here is what I have figured out so far... Almost there.
UPDATED CODE AND CANVAS HERE: https://gyazo.com/d12b9a831f50c25f8f854dc2143c93dc
import SwiftUI
struct CustomBlock: View {
var leading: String
var trailing: String
var body: some View {
VStack {
HStack (alignment: .firstTextBaseline, spacing: 18){
Button(action: {}){
Text(leading)
.bold()
.font(Font.custom("Helvetica Neue", size: 21.0))
.padding(25)
.foregroundColor(Color.white)
.background(Color.green)
.cornerRadius(12)
.multilineTextAlignment(.center)
.fixedSize()
.frame(width: 150, height: 50, alignment: .center)
}
Button(action: {}){
Text(trailing)
.bold()
.font(Font.custom("Helvetica Neue", size: 21.0))
.padding(25)
.foregroundColor(Color.white)
.background(Color.green)
.cornerRadius(12)
.multilineTextAlignment(.center)
.fixedSize()
.frame(width: 150, height: 50, alignment: .center)
}
}
}.padding()
}
}
struct ContentView: View {
var body: some View {
ZStack {
Color.init(hue: 0.2722, saturation: 0.89, brightness: 0.29, opacity: 1.0) .edgesIgnoringSafeArea(.all)
VStack {
HStack {
StrokeText(text: "Dividend Chaser", width: 0.5, color: .black)
.foregroundColor(.white)
.font(.system(size: 45, weight: .bold))
}
ZStack {
RoundedRectangle(cornerRadius: 25, style: .continuous)
.fill( Color.init(red: 0.33, green: 0.56, blue: 0.27))
.frame(width: 350, height: 240)
}
CustomBlock(leading: "Today's List", trailing: "Tomorrow's List").lineLimit(2)
CustomBlock(leading: "This Month", trailing: "Next Month").lineLimit(2)
CustomBlock(leading: "3% Yeild Or Higher", trailing: "5% Yeild Or Higher").lineLimit(2)
CustomBlock(leading: "App Help", trailing: "More Apps").lineLimit(2)
}
}
}
}
Here is a demo of approach. Tested with Xcode 12 / iOS 14.
struct DemoButtonStyle: ButtonStyle {
func makeBody(configuration: Configuration) -> some View {
configuration.label
.foregroundColor(.white).font(Font.body.bold())
.frame(maxWidth: .infinity).padding(.vertical, 10)
.background(RoundedRectangle(cornerRadius: 8).fill(Color.green))
.multilineTextAlignment(.center)
.frame(maxWidth: .infinity)
}
}
struct TestButtonsGridLayout: View {
var body: some View {
VStack(spacing: 1) {
HStack(spacing: 1) {
Button("Today's\nList") {}
Button("Tomorrow's\nList") {}
}
HStack(spacing: 1) {
Button("This\nMonth") {}
.overlay(RoundedRectangle(cornerRadius: 8)
.stroke(lineWidth: 4).foregroundColor(.white).padding(2))
Button("Next\nMonth") {}
}
// .. other same here
}.buttonStyle(DemoButtonStyle())
}
}
Note: a) button style can be applied per-button b) show overlay selection can be also moved in style and activated by some state variable.

Home page view background color in not on full screen in iPhone 11 Simulator

I am trying to build an app in SwiftUI and facing 1 challenge (Xcode Version 11.5) -
While running app on iPhone 11 simulator, background color is not coming on entire screen, bottom part of screen is still white however while running it on iPhone 8 simulator, it works fine. Not sure if it is simulator issue or code issue. I tried to add Spacer, change VStack, HStack but it did not work.
struct HomePageView: View {
#State var size = UIScreen.main.bounds.width / 1.6
var body: some View {
GeometryReader{geometry in
VStack {
HStack {
ZStack{
NavigationView{
ZStack {
ScrollView(.vertical, showsIndicators: false) {
VStack {
View1()
}.frame( maxWidth: .infinity)
}
.navigationBarItems(leading: Button(action: {
self.size = 10
}, label: {
Image("menu")
.resizable()
.frame(width: 30, height: 30)
}).foregroundColor(.appHeadingColor), trailing:
Button(action: {
print("profile is pressed")
}) {
HStack {
NavigationLink(destination: ProfileView()) {
LinearGradient.lairHorizontalDark
.frame(width: 30, height: 30)
.mask(
Image(systemName: "person.crop.circle")
.resizable()
.scaledToFit()
)
}
}
}
).navigationBarTitle("Home", displayMode: .inline)
}
}
HStack{
menu(size: self.$size)
.cornerRadius(20)
.padding(.leading, -self.size)
.offset(x: -self.size)
Spacer().background(Color.lairBackgroundGray)
}
//Spacer()
}.animation(.spring()).background(Color.lairBackgroundGray)
//Spacer()
}.padding(.top, UIApplication.shared.windows.first?.safeAreaInsets.top)
.padding(.bottom, UIApplication.shared.windows.first?.safeAreaInsets.bottom)
}.frame(height: geometry.size.height).background(Color.lairBackgroundGray)
}//.background(Color.lairBackgroundGray.edgesIgnoringSafeArea(.all))
}
}
Below is my another view which basically get painted on screen as part of home view. Please forgive me to put so much code here but wanted to make sure if it is not because of View1 -
struct View1: View {
#State var index = 0
var body: some View{
// ScrollView {
GeometryReader { geometry in
VStack{
HStack{
VStack {
ZStack{
Circle()
.trim(from: 0, to: 1)
.stroke(Color.lairDarkGray.opacity(0.09), style: StrokeStyle(lineWidth: 34, lineCap: .round))
.frame(width: 80, height: 80)
Circle()
.trim(from: 0, to: 0.5)
.stroke(LinearGradient(gradient: Gradient(colors: [.buttonGradientStartColor, .buttonGradientEndColor]), startPoint: UnitPoint(x: -0.2, y: 0.5), endPoint: .bottomTrailing), style: StrokeStyle(lineWidth: 34, lineCap: .round))
.frame(width: 80 , height: 80)
.rotationEffect(.init(degrees: -90))
Text("15")
.font(.system(size:30))
.fontWeight(.bold)
}.padding()
Text("Day(s)")
.foregroundColor(Color.black.opacity(0.8))
}.frame(height: 100)
VStack(alignment: .leading, spacing: 12){
HStack {
Image("1")
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 170, height: 170)
}
.background(Color.lairBackgroundGray)
//.padding(.bottom, 5)
}
.padding(.leading, 20)
Spacer(minLength: 0)
}
.padding(.horizontal, 20)
}//.frame(height: geometry.size.height)
.background(Color.lairBackgroundGray.edgesIgnoringSafeArea(.all))
}
//}
}
}[![enter image description here][1]][1]
You just need to add
.edgesIgnoringSafeArea(.all)
to the view that you want to go fullscreen
After recreating entire view and removing some unnecessary view, i was able to resolve this iissue.

Add new item in Scroll View in SwiftUI

I'm trying to add a new view inside the Scroll View that contains a button every time that I click in the blue button in the bottom
]1
Here i create the scroll view with 2 buttons, and want to add more after I click in the button on the right
HStack{
ScrollView(.horizontal, content: {
HStack{
PageStep()
PageStep()
}
})
Button(action: {
self.addNewStep = true
}) {
Image(systemName: "plus.square")
.frame(width: 75, height: 75)
.overlay(
RoundedRectangle(cornerRadius: 10)
.stroke(Color.blue, lineWidth: 5)
)
}.buttonStyle(PlainButtonStyle()).padding(.trailing, 10)
}
.padding(.leading, 10)
.frame(minWidth: 0, maxWidth: UIScreen.main.bounds.width, minHeight: 80, alignment: .bottom)
.foregroundColor(Color.blue)
struct PageStep: View {
var stepPossition = String()
var body: some View {
Button(action: {
print("Entrou")
}){
Rectangle()
.fill(Color.red)
.frame(width: 75, height: 75)
.cornerRadius(10)
}
}
}
Here is possible approach. Tested with Xcode 11.4.
struct ContentView: View {
#State private var steps = 2 // pages counter
var body: some View {
HStack{
ScrollView(.horizontal, content: {
HStack{
// create available pages
ForEach(0..<steps, id: \.self) { i in
PageStep(stepPossition: "\(i)").id(i) // inject
}
}
})
Button(action: {
self.steps += 1 // << add next page
}) {
Image(systemName: "plus.square")
.frame(width: 75, height: 75)
.overlay(
RoundedRectangle(cornerRadius: 10)
.stroke(Color.blue, lineWidth: 5)
)
}.buttonStyle(PlainButtonStyle()).padding(.trailing, 10)
}
.padding(.leading, 10)
.frame(minWidth: 0, maxWidth: UIScreen.main.bounds.width, minHeight: 80, alignment: .bottom)
.foregroundColor(Color.blue)
}
}
struct PageStep: View {
var stepPossition: String
var body: some View {
Button(action: {
print("Entrou")
}){
Rectangle()
.fill(Color.red)
.frame(width: 75, height: 75)
.cornerRadius(10)
}
}
}

SwiftUI won't align ZStacks

I'm currently trying to handle SwiftUI by following a tutorial, but somehow I can't solve one issue:
I created another View, namely my HomeView.swift - this file contains the following code:
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()
}
}
}
As you can see, right in the beginning, inside of my Home struct, I tried to align two ZStacks - one .topLeading and one .topTrailing. Reading the docs, this should change its position, but somehow it doesn't. Both stack stay centered.
BTW I haven't particularly touched ContenView.swift yet.
Actually, for either inner ZStack, you need to set frames. This can make them reach edges.
ZStack{
ZStack{
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()
}.frame(maxWidth: .infinity, maxHeight: .infinity, alignment: .topLeading)
ZStack{
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()
}.frame(maxWidth: .infinity, maxHeight: .infinity, alignment: .topTrailing)
MenuView(show: $show)
}
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)
}
}
}
Is this the layout that you are looking for? With VStack and HStack you can align the views to the top and on both edges

How to create View inside another view with SwiftUI?

I need to make such a simple thing, but can't figure out how.
So I need to create a View which I already have inside another view. Here how it looks like now ↓
Here's my button:
struct CircleButton: View {
var body: some View {
Button(action: {
self
}, label: {
Text("+")
.font(.system(size: 42))
.frame(width: 57, height: 50)
.foregroundColor(Color.white)
.padding(.bottom, 7)
})
.background(Color(#colorLiteral(red: 0.4509803922, green: 0.8, blue: 0.5490196078, alpha: 1)))
.cornerRadius(50)
.padding()
.shadow(color: Color.black.opacity(0.15),
radius: 3,
x: 0,
y: 4)
}
}
Here's a view which I want to place when I tap the button ↓
struct IssueCardView: View {
var body: some View {
ZStack (alignment: .leading) {
Rectangle()
.fill(Color.white)
.frame(height: 50)
.shadow(color: .black, radius: 20, x: 0, y: 4)
.cornerRadius(8)
VStack (alignment: .leading) {
Rectangle()
.fill(Color(#colorLiteral(red: 0.6550863981, green: 0.8339114785, blue: 0.7129291892, alpha: 1)))
.frame(width: 30, height: 8)
.cornerRadius(8)
.padding(.horizontal, 10)
Text("Some text on card here")
.foregroundColor(Color(UIColor.dark.main))
.font(.system(size: 14))
.fontWeight(.regular)
.padding(.horizontal, 10)
}
}
}
}
Here's a view where I want to place this IssueCardView ↓. Instead of doing it manually like now I want to generate this View with button.
struct TaskListView: View {
var body: some View {
ScrollView(.vertical, showsIndicators: false, content: {
VStack (alignment: .leading, spacing: 8) {
**IssueCardView()
IssueCardView()
IssueCardView()
IssueCardView()
IssueCardView()**
}
.frame(minWidth: 320, maxWidth: 500, minHeight: 500, maxHeight: .infinity, alignment: .topLeading)
.padding(.horizontal, 0)
})
}
}
Although it works with scrollView and stack, You should use a List for these kind of UI issues (as you already mentioned in the name of TaskListView)
struct TaskListView: View {
typealias Issue = String // This is temporary, because I didn't have the original `Issue` type
#State var issues: [Issue] = ["Some issue", "Some issue"]
var body: some View {
ZStack {
List(issues, id: \.self) { issue in
IssueCardView()
}
CircleButton {
self.issues += ["new issue"]
}
}
}
}
I have added let action: ()->() to CircleButton. So I can pass the action to it.
