View with fullscreen image and navigationLink - ios

i'm new to swiftui and struggling with some basic stuff
I'm trying to create a view with 2 buttons on the botton.
I want an image as background of the whole view.
var body: some View {
ZStack {
Image("bg-welcome").edgesIgnoringSafeArea(.all)
}
}
This works fine
I set my view like this
NavigationView {
ZStack {
VStack(alignment: HorizontalAlignment.leading, spacing: 10) {
Text("1").foregroundColor(.white)
Text("2").foregroundColor(.white)
Spacer()
Button(action: {}){
Text("ooooooooo")
}
}.background(Image("bg-welcome"))
}
}
Now I have 2 problems:
- a white space is dispalyed just before the background image
- the first text is pushed below, surely after the space reserved for the navigationbar and I don't want it because when I navigate to the next screen, the space is still taken and I want to have the whole avaiblable screen
thank you for your help

try this:
var body: some View {
NavigationView {
ZStack {
VStack(alignment: HorizontalAlignment.leading, spacing: 10) {
Text("1").foregroundColor(.white)
Text("2").foregroundColor(.white)
Spacer()
Button(action: {}){
Text("Button 1")
}
Button(action: {}){
Text("Button 2")
}
}.background(Image("remachine_poster")
.resizable()
.aspectRatio(contentMode: .fill)).edgesIgnoringSafeArea(.all)
}
}
}

you can add a padding to your button....
NavigationView {
ZStack {
VStack() {
Text("1").foregroundColor(.green).padding(.top, 40)
Text("2").foregroundColor(.green)
Spacer()
Button(action: {}){
Text("Button 1")
}.foregroundColor(Color.red)
Button(action: {}){
Text("Button 2")
}.foregroundColor(Color.red)
}
}.background(Image("remachine_poster")
.resizable()
.aspectRatio(contentMode: .fill))
.edgesIgnoringSafeArea(.vertical)
}

I ended up doing something like this.
Please let me know if there is a better way
NavigationView {
GeometryReader { gr in
ZStack {
VStack(alignment: HorizontalAlignment.center, spacing: 10) {
HStack{
Spacer()
}
Text("1").foregroundColor(.white).padding(EdgeInsets(top: 30, leading: 0, bottom: 0, trailing: 0))
Text("2").foregroundColor(.white)
Spacer()
HStack {
NavigationLink(destination: SigninScreen()){
Text("Button 1")
}
Button(action: {}){
Text("Button 2")
}
}.padding()
}.background(Image("bg-welcome")
.resizable()
.aspectRatio(contentMode: .fill)).edgesIgnoringSafeArea(.all)
}.navigationBarHidden(true)
}

Swift ui stacks causing gap at the top of the screen when frame should be first

In Swift ui I have a tabview and am going to my profile test page but in the simulator it displaying in the middle of the page.
var body: some View {
VStack() {
Text("Welcome")
.font(.largeTitle)
.foregroundColor(.black)
ZStack {
RoundedRectangle(cornerRadius: 25, style: .continuous)
.fill(.red)
VStack {
Image("murry")
.clipShape(Circle())
.shadow(radius: 10)
.overlay(Circle()
.stroke(Color.red, lineWidth: 5))
Text("Murry GoldBerg")
HStack{
Text("Following:0").foregroundColor(.white)
Text("Followers:2").foregroundColor(.white)
Text("Kids:0").foregroundColor(.white)
}
}
.padding(20)
.multilineTextAlignment(.center)
}
.frame(width: 450, height: 250)
}
Spacer()
}
}
My Code as to how am inserting my views in the tab view not showing it all as no need just a snippet
struct ContentView: View {
var body: some View {
TabView{
HomeView() .tabItem {
Image(systemName: "house")
Text("Home")
}
ProfileView()
.tabItem {
Image(systemName: "person.circle.fill")
Text("Profile")
}
StatsView()
.tabItem {
Image(systemName: "plus").renderingMode(.original).padding()
Text("Plus")
}
}
Even on a real device it is doing the same so I no its not just the simlutor.
The reason is there is only one VStack so it will be default the main layout of the view. Default VStack if has only one view is from center view.
You just need add another VStack to cover your VStack then it will layout from top
var body: some View {
VStack {
VStack() {
Text("Welcome")
.font(.largeTitle)
.foregroundColor(.black)
ZStack {
RoundedRectangle(cornerRadius: 25, style: .continuous)
.fill(.red)
VStack {
Image("murry")
.clipShape(Circle())
.shadow(radius: 10)
.overlay(Circle()
.stroke(Color.red, lineWidth: 5))
Text("Murry GoldBerg")
HStack{
Text("Following:0").foregroundColor(.white)
Text("Followers:2").foregroundColor(.white)
Text("Kids:0").foregroundColor(.white)
}
}
.padding(20)
.multilineTextAlignment(.center)
}
.frame(width: 450, height: 250)
Spacer()
}
}
}

How to create design covering back button and top bar fully with cross button above it?

I am trying to create below design using swiftUI but not able to find proper approach.
I tried but my image is not covering back button but coming below to back button
Expected design
VStack(spacing: 16) {
VStack {
ZStack(alignment: .topTrailing) {
Image("defaultImage")
.resizable()
.frame( height: 200)
Button("Cancel", action: {
print("cancel")
})
.padding(12)
}
}
}
My Design :(
You might want to do a lot of try in SwiftUI to get a custom design right. gave it a quick try for you and added comments on the code so you can understand most of what i did.
this is the quick result i got (with a random background i got on internet)
import SwiftUI
struct FirstView: View{
var body: some View{
NavigationView {
VStack{
NavigationLink(destination: BackgroundImageNav()){
Text("Go to the view")
.font(.title)
}
}
}
}
}
struct BackgroundImageNav: View {
#Environment(\.presentationMode) var presentationMode
// remplacing the back button action, (only problem is that this disable the swipe back)
var body: some View {
ZStack {
// ZStack help you having your image behind the other views
VStack {
Image("defaultImage")
.resizable()
.frame(height: 180)
.edgesIgnoringSafeArea(.all)
Spacer()
// having a spacer that push the image on the top and ignoring the safe area
}
VStack(alignment:.leading){
HStack{
Button(action:{
presentationMode.wrappedValue.dismiss()
// back button action
}){
Image(systemName:"chevron.left")
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 30, height: 30)
.foregroundColor(.white)
}
Spacer()
Rectangle()
.fill(Color.white)
.frame(width: 200, height: 80, alignment: .center)
Spacer()
Button(action:{
// do something
}){
Image(systemName: "xmark")
.resizable()
.frame(width: 24, height: 24)
.foregroundColor(.white)
}
}.padding()
Text("Title")
.bold()
.font(.title)
.foregroundColor(.black)
.background(Color.white)
.padding(24)
Spacer()
}
}.navigationBarHidden(true)
// removing the bar to customize the back button
}
}
struct backgroundImage_Previews: PreviewProvider {
static var previews: some View {
FirstView()
}
}

How to add navigation button link in button in SwiftUI?

I want to nagivate to the details screen using button. the buttons are designed in a separate view and called Using ForEach function. Please guide me to solve this.
This is the code I designed for button
struct ButtonsDesignView: View {
var buttons: MyModel.buttons
var body: some View {
Button(action: { }) {
ZStack {
HStack{
VStack{
Text(btn.title)
.foregroundColor(Color(.blue))
.padding()
Text(btn.subtitle)
.foregroundColor(Color(.blue))
.padding()
}
Spacer()
VStack{
Image(systemName: (btn.image))
.resizable()
.scaledToFit()
.foregroundColor(Color(.blue))
.padding()
}
}
}
}
This is code code I've place in ContentView to call display the buttons in scrollview Using ForEach.
ScrollView(.vertical, showsIndicators: false)
{
ForEach(buttonsData) {
item in
NavigationLink(destination: DetailView(buttons: item))
{
ButtonsDesignView(buttons: item)
.padding(10)
}
}.padding(.horizontal, 30)
}
But with this code navigation link is not working.
You should add navigationLink to ButtonDesignView.
I think that this should work;
NavigationLink(destination: DetailView(buttons: buttons)) {
Button(action: { }) {
ZStack {
HStack{
VStack{
Text(btn.title)
.foregroundColor(Color(.blue))
.padding()
Text(btn.subtitle)
.foregroundColor(Color(.blue))
.padding()
}
Spacer()
VStack{
Image(systemName: (btn.image))
.resizable()
.scaledToFit()
.foregroundColor(Color(.blue))
.padding()
}
}
}
}
}

Applying resizable() on an Image affects text in SwiftUI

I am working on SwiftUI to make a widget and I can't figure out if I'm doing something wrong or there's a bug in SwiftUI.
I have an Image that I use as a background and at the top there's a text. If I apply resizable() to the Image it also affects the behaviour of the text.
var body: some View {
ZStack {
VStack {
Image(affirmation.customImageName ?? "c_0")
.resizable()
.scaledToFill()
.clipped()
}
HStack {
Text(affirmation.title)
.font(.body)
.multilineTextAlignment(.leading)
.lineLimit(nil)
Spacer()
}
.padding(.leading, 5)
.padding(.top, 5)
}
}
Creates this view:
While this code:
var body: some View {
ZStack {
VStack {
Image(affirmation.customImageName ?? "c_0")
.scaledToFill()
.clipped()
}
HStack {
Text(affirmation.title)
.font(.body)
.multilineTextAlignment(.leading)
.lineLimit(nil)
Spacer()
}
.padding(.leading, 5)
.padding(.top, 5)
}
}
Creates this view:

Remove circular button background in SwiftUI (WatchKit)

I'm struggling to remove the background of a custom circular Button element in SwiftUI which is defined as follows:
struct NavButton: View {
var body: some View {
Button(action: {})
VStack {
Text("Button")
}
.padding(40)
.background(Color.red)
.font(.title)
.mask(Circle())
}
}
}
This results in a rectangular light gray background around the button, where I want it to not be shown:
I tried to append a "background" modifier to the button, and it demonstrates very strange behavior: if it's set to "Color.clear", there is no effect. But if I set it to "Color.green" it does change the background as expected.
Example of setting the "Background" modifier to "Color.green":
struct NavButton: View {
var body: some View {
Button(action: {})
VStack {
Text("Button")
}
.padding(40)
.background(Color.red)
.font(.title)
.mask(Circle())
}
.background(Color.green) // has no effect if set to "Color.clear"
}
}
I wonder if I'm missing something here?
PS: I'm using Xcode 11.1 (11A1027)
Try adding .buttonStyle(PlainButtonStyle()) on the button itself.
You would have something like this:
Button(action: {}){
VStack{
Text("Button")
}
.padding(40)
.background(Color.red)
.font(.headline)
.mask(Circle())
}
.buttonStyle(PlainButtonStyle())
Declare your own ButtonStyle:
struct RedRoundButton: ButtonStyle {
func makeBody(configuration: Configuration) -> some View {
configuration.label
.padding(40)
.font(.title)
.background( Circle()
.fill(Color.red))
}
}
and then use it like this:
Button("Button") {}
.buttonStyle(RedRoundButton())
Try this:
struct ContentView: View {
var body: some View {
Button(action: {}) {
Text("Button")
.frame(width: 80, height: 80)
}
.background(Color.red)
.cornerRadius(40)
.frame(width: 80, height: 80)
}
}
Try this.
struct ContentView: View {
var body: some View {
VStack {
Button(action: {}){
Text("button")
.font(.system(size: 50))
.foregroundColor(.black)
.bold()
}
.padding(30)
.background(Color.yellow)
.font(.headline)
.mask(Circle())
.buttonStyle(PlainButtonStyle())
} // end Vstack
}// end body
}
