The code below is to create a custom button
import SwiftUI
let skyBlue = Color(red: 75/255, green: 170/255, blue: 193/255)
struct RegisterButtonView: View {
var body: some View {
GeometryReader { geo in
HStack {
Spacer()
Text("Register")
.foregroundColor(Color(.white))
.font(.system(size: geo.size.width / 20))
.bold()
Spacer()
}
.frame(width: geo.size.width * 4/9, height: geo.size.height / 7)
.background(skyBlue)
.cornerRadius(60)
}
}
}
struct RegisterButtonView_Previews: PreviewProvider {
static var previews: some View {
RegisterButtonView()
}
}
However, the whole button view contains the extra space introduced by the GeometryReader, so that when I put this view to a root view, the space cannot be eliminated.
You may need to set the frame of GeoReader directly.
struct RegisterButtonView: View {
var body: some View {
GeometryReader { geo in
HStack {
Spacer()
Text("Register")
.foregroundColor(Color(.white))
.font(.system(size: geo.size.width / 20 * 9 / 4))
.bold()
Spacer()
}
.frame(width: geo.size.width , height: geo.size.height )
.background(skyBlue)
.cornerRadius(60)
}.frame(width: UIScreen.main.bounds.width * 4/9 , height: UIScreen.main.bounds.height / 7)
}
}
