I don't really follow why the following button:
Button { } label: {
Image(systemName: "globe")
.resizable()
.scaledToFill()
}
.frame(width: size, height: size)
.border(.yellow)
is behaving differently in the body and in the NavigationView?
Why isn't the one in the NavigationView filling the entire frame?
struct ContentView: View {
let size = 45.0
let fontSize = 17.0
var body: some View {
NavigationView {
Button { } label: {
Image(systemName: "globe")
.resizable()
.scaledToFill()
}
.frame(width: size, height: size)
.border(.yellow)
.toolbar {
HStack(alignment: .top) {
Button { } label: {
Image(systemName: "globe")
.resizable()
.scaledToFill()
}
.frame(width: size, height: size)
.border(.red)
// Image and Title
VStack {
Image("nemo")
.resizable()
.scaledToFit()
.frame(height: size)
Text("Navigation Title")
.font(.system(size: fontSize))
.bold()
}.border(.green)
}
//.frame(maxWidth: .infinity)
}
}
}
}
This is a design of default button in toolbar, instead we can use custom, like
Button { print(">> action here")} label: {
Image(systemName: "globe")
.resizable()
.scaledToFill()
}
.buttonStyle(MyTabbarButtonStyle())
.frame(width: size, height: size)
.border(.red)
// and style (tune colours as you want)
struct MyTabbarButtonStyle: ButtonStyle {
func makeBody(configuration: Configuration) -> some View {
configuration.label
.foregroundColor(configuration.isPressed ? .gray : .blue)
}
}
I want to add button with image inside of the view like twitter button with image for SwiftUI 2, but it is not padding to any directions.
struct WeatherView: View {
var body: some View {
VStack(alignment: .leading, spacing:0){
Button(action: {}) {
Image("cloud")
.padding()
.background(Color.blue)
.foregroundColor(Color.white)
.clipShape(Circle())
.shadow(radius: 8)
}
HStack(spacing: 5){
Text("Rainy")
.font(.largeTitle)
.fontWeight(.medium)
Spacer()
Button(action: {
}) {
Image("menu").resizable().frame(width: 24, height: 24)
}
}
.foregroundColor(Color("black"))
.padding()
Spacer()
}
}
}
Is there any solution for this problem.
I hope you are doing well.
This code should do the trick.
VStack {
Spacer()
Button(action: {}) {
Image(systemName: "cloud.fill")
.padding()
.background(Color.blue)
.foregroundColor(Color.white)
.clipShape(Circle())
.shadow(radius: 8)
}
}
.frame(maxWidth: .infinity, alignment: .trailing)
.padding()
By putting the button in a VStack, and putting a spacer before it, you will push the button to the bottom of the screen. Then by putting a frame on it, and making the width to be .infinity, and giving it alignment trailing, you will further push the button to the trailing side of the screen, which in this case results in making the button at the bottom right corner.
Edit: Included full code
struct WeatherView: View {
var body: some View {
VStack(alignment: .leading, spacing: 0) {
HStack(spacing: 5) {
Text("Rainy")
.foregroundColor(.black)
.font(.largeTitle)
.fontWeight(.medium)
Spacer()
Button(action: {}) {
Image("menu").resizable().frame(width: 24, height: 24)
}
}
.foregroundColor(Color("black"))
.padding()
VStack {
Spacer()
Button(action: {}) {
Image("cloud")
.padding()
.background(Color.blue)
.foregroundColor(Color.white)
.clipShape(Circle())
.shadow(radius: 8)
}
}
.frame(maxWidth: .infinity, alignment: .trailing)
.padding()
}
}
}
How can I restrict the view to resize only downwards?
I am trying to add more buttons & have the view resize to accommodate the buttons without overlapping the red rectangle above.
This is the code I am currently using:
struct ContentView: View {
var body: some View {
VStack{
RoundedRectangle(cornerRadius: 20)
.frame(width: .infinity, height: 55)
.foregroundColor(.red)
HStack{
Spacer()
ZStack{
RoundedRectangle(cornerRadius: 20)
.foregroundColor(.green)
VStack{
Button(action: {}) {
Text("Test Button")
.foregroundColor(.white)
.font(.headline)
.frame(width: .infinity)
Spacer()
}.padding()
Button(action: {}) {
Text("Test Button")
.foregroundColor(.white)
.font(.headline)
.frame(width: .infinity)
Spacer()
}.padding()
Button(action: {}) {
Text("Test Button")
.foregroundColor(.white)
.font(.headline)
.frame(width: .infinity)
Spacer()
}.padding()
}
}.frame(width: 250, height: 100)
}
Spacer()
}
}
}
Change your .frame(width: 250, height: 100) to .frame(width: 250, height: 100, alignment: .top) Your original example defaults to .center, which is why it expands into the red rectangle.
I'm trying to get from one SwiftUI view to another SwiftUI view and I'm using a NavigationLink as per the code below, but I'm getting the error: Cannot invoke initializer for type 'NavigationLink<_, _>' with an argument list of type '(destination: PlaylistTable)'
Below is my code for the button which triggers the link to the next view:
struct MusicButton: View {
var body: some View {
NavigationView {
Button(action: {
NavigationLink(destination: PlaylistTable())
})
{ Image(systemName: "music.note.list")
.resizable()
.foregroundColor(Color.white)
.frame(width: 25, height: 25, alignment: .center)
.aspectRatio(contentMode: .fit)
.font(Font.title.weight(.ultraLight))
}
}
}
}
Don't put NavigationLink inside a Button will solve your problem:
NavigationView {
NavigationLink(destination: PlaylistTable())
{ Image(systemName: "music.note.list")
.resizable()
.foregroundColor(Color.white)
.frame(width: 25, height: 25, alignment: .center)
.aspectRatio(contentMode: .fit)
.font(Font.title.weight(.ultraLight))
}
}
If you want to use the button, then move the navigation link to the background.
struct MusicButton: View {
#State var isActive = false
var body: some View {
NavigationView {
Button(action: {
isActive.toggle()
})
{ Image(systemName: "music.note.list")
.resizable()
.foregroundColor(Color.white)
.frame(width: 25, height: 25, alignment: .center)
.aspectRatio(contentMode: .fit)
.font(Font.title.weight(.ultraLight))
}
}
.background(
NavigationLink(destination: PlaylistTable(), isActive: $isActive) {EmptyView()}
)
}
}
The background area of my button is not detecting user interaction. Only way to interact with said button is to tap on the Text/ Label area of the button. How to make entire Button tappable?
struct ScheduleEditorButtonSwiftUIView: View {
#Binding var buttonTagForAction : ScheduleButtonType
#Binding var buttonTitle : String
#Binding var buttonBackgroundColor : Color
let buttonCornerRadius = CGFloat(12)
var body: some View {
Button(buttonTitle) {
buttonActionForTag(self.buttonTagForAction)
}.frame(minWidth: (UIScreen.main.bounds.size.width / 2) - 25, maxWidth: .infinity, minHeight: 44)
.buttonStyle(DefaultButtonStyle())
.lineLimit(2)
.multilineTextAlignment(.center)
.font(Font.subheadline.weight(.bold))
.foregroundColor(Color.white)
.border(Color("AppHighlightedColour"), width: 2)
.background(buttonBackgroundColor).opacity(0.8)
.tag(self.buttonTagForAction)
.padding([.leading,.trailing], 5)
.cornerRadius(buttonCornerRadius)
}
}
The proper solution is to use the .contentShape() API.
Button(action: action) {
HStack {
Spacer()
Text("My button")
Spacer()
}
}
.contentShape(Rectangle())
You can change the provided shape to match the shape of your button; if your button is a RoundedRectangle, you can provide that instead.
I think this is a better solution, add the .frame values to the Text() and the button will cover the whole area 😉
Button(action: {
//code
}) {
Text("Click Me")
.frame(minWidth: 100, maxWidth: .infinity, minHeight: 44, maxHeight: 44, alignment: .center)
.foregroundColor(Color.white)
.background(Color.accentColor)
.cornerRadius(7)
}
You can define content Shape for hit testing by adding modifier: contentShape(_:eoFill:)
And important thing is you have to apply inside the content of Button.
Button(action: {}) {
Text("Select file")
.frame(width: 300)
.padding(100.0)
.foregroundColor(Color.black)
.contentShape(Rectangle()) // Add this line
}
.background(Color.green)
.cornerRadius(4)
.buttonStyle(PlainButtonStyle())
Another
Button(action: {}) {
VStack {
Text("Select file")
.frame(width: 100)
Text("Select file")
.frame(width: 200)
}
.contentShape(Rectangle()) // Add this inside Button.
}
.background(Color.green)
.cornerRadius(4)
.buttonStyle(PlainButtonStyle())
This fixes the issue on my end:
var body: some View {
GeometryReader { geometry in
Button(action: {
// Action
}) {
Text("Button Title")
.frame(
minWidth: (geometry.size.width / 2) - 25,
maxWidth: .infinity, minHeight: 44
)
.font(Font.subheadline.weight(.bold))
.background(Color.yellow).opacity(0.8)
.foregroundColor(Color.white)
.cornerRadius(12)
}
.lineLimit(2)
.multilineTextAlignment(.center)
.padding([.leading,.trailing], 5)
}
}
Is there a reason why you are using UIScreen instead of GeometryReader?
Short Answer
Make sure the Text (or button content) spans the length of the touch area, AND use .contentShape(Rectangle()).
Button(action:{}) {
HStack {
Text("Hello")
Spacer()
}
.contentShape(Rectangle())
}
Long Answer
There are two parts:
The content (ex. Text) of the Button needs to be stretched
The content needs to be considered for hit testing
To stretch the content (ex. Text):
// Solution 1 for stretching content
HStack {
Text("Hello")
Spacer()
}
// Solution 2 for stretching content
Text("Hello")
.frame(maxWidth: .infinity, alignment: .leading)
// Alternatively, you could specify a specific frame for the button.
To consider content for hit testing use .contentShape(Rectangle()):
// Solution 1
Button(action:{}) {
HStack {
Text("Hello")
Spacer()
}
.contentShape(Rectangle())
}
// Solution 2
Button(action:{}) {
Text("Hello")
.frame(maxWidth: .infinity, alignment: .leading)
.contentShape(Rectangle())
}
You might be doing this:
Button { /*to do something on button click*/}
label: { Text("button text").foregroundColor(Color.white)}
.frame(width: 45, height: 45, alignment: .center)
.background(Color.black)
Solution:
Button(action: {/*to do something on button click*/ })
{
HStack {
Spacer()
Text("Buttton Text")
Spacer() } }
.frame(width: 45, height: 45, alignment: .center)
.foregroundColor(Color.white)
.background(Color.black).contentShape(Rectangle())
A bit late to the answer, but I found two ways to do this —
Option 1: Using Geometry Reader
Button(action: {
}) {
GeometryReader { geometryProxy in
Text("Button Title")
.font(Font.custom("SFProDisplay-Semibold", size: 19))
.foregroundColor(Color.white)
.frame(width: geometryProxy.size.width - 20 * 2) // horizontal margin
.padding([.top, .bottom], 10) // vertical padding
.background(Color.yellow)
.cornerRadius(6)
}
}
Option 2: Using HStack with Spacers
HStack {
Spacer(minLength: 20) // horizontal margin
Button(action: {
}) {
Text("Hello World")
.font(Font.custom("SFProDisplay-Semibold", size: 19))
.frame(maxWidth:.infinity)
.padding([.top, .bottom], 10) // vertical padding
.background(Color.yellow)
.foregroundColor(Color.white)
.cornerRadius(6)
}
Spacer(minLength: 20)
}.frame(maxWidth:.infinity)
My thought process here is that although option 1 is more succinct, I would choose option 2 since it's less coupled to its parent's size (through GeometryReader) and more in line of how I think SwiftUI is meant to use HStack, VStack, etc.
I was working with buttons and texts that need user interaction when I faced this same issue. After looking and testing many answers (including some from this post) I ended up making it works in the following way:
For buttons:
/* WITH IMAGE */
Button {
print("TAppeD")
} label: {
Image(systemName: "plus")
.frame(width: 40, height: 40)
}
/* WITH TEXT */
Button {
print("TAppeD")
} label: {
Text("My button")
.frame(height: 80)
}
For Texts:
Text("PP")
.frame(width: 40, height: 40)
.contentShape(Rectangle())
.onTapGesture {
print("TAppeD")
}
In the case of the texts, I only need the .contentShape(Rectangle()) modifier when the Text doesn't have a .background in order to make the entire Text frame responsive to tap gesture, while with buttons I use my Text or Image view with a frame and neither a .background nor a .contentShape is needed.
Image of the following code in preview (I'm not allowed to include pictures yet )
import SwiftUI
struct ContentView: View {
#State var tapped: Bool = true
var body: some View {
VStack {
RoundedRectangle(cornerRadius: 19)
.frame(width: 40, height: 40)
.foregroundColor(tapped ? .red : .green)
Spacer()
HStack (spacing: 0) {
Text("PP")
.frame(width: 40, height: 40)
.contentShape(Rectangle())
.onTapGesture {
tapped.toggle()
}
Button {
print("TAppeD")
tapped.toggle()
} label: {
Image(systemName: "plus")
.frame(width: 40, height: 40)
}
.background(Color.red)
Button {
print("TAppeD")
tapped.toggle()
} label: {
Text("My button")
.frame(height: 80)
}
.background(Color.yellow)
}
Spacer()
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
this way makes the button area expand properly
but if the color is .clear, it dosen't work🤷♂️
Button(action: {
doSomething()
}, label: {
ZStack {
Color(.white)
Text("some texts")
}
})
When I used HStack then it worked for button whole width that's fine, But I was facing issue with whole button height tap not working at corners and I fixed it in below code:
Button(action:{
print("Tapped Button")
}) {
VStack {
//Vertical whole area covered
Text("")
Spacer()
HStack {
//Horizontal whole area covered
Text("")
Spacer()
}
}
}
If your app needs to support both iOS/iPadOS and macOS, you may want to reference my code!
Xcode 14.1 / iOS 14.1 / macOS 13.0 / 12-09-2022
Button(action: {
print("Saved to CoreData")
}) {
Text("Submit")
.frame(minWidth: 100, maxWidth: .infinity, minHeight: 44, maxHeight: 60, alignment: .center)
.foregroundColor(Color.white)
#if !os(macOS)
.background(Color.accentColor)
#endif
}
#if os(macOS)
.background(Color.accentColor)
#endif
.cornerRadius(7)
Easier work around is to add .frame(maxWidth: .infinity) modifier.
and wrap your button inside a ContainerView. you can always change the size of the button where it's being used.
Button(action: tapped) {
HStack {
if let icon = icon {
icon
}
Text(title)
}
.frame(maxWidth: .infinity) // This one
}
