Set Toggle color in SwiftUI
SwiftUI 3.0
Using tint
A new modifier was introduced that can also change the Toggle color:
Toggle(isOn: $isToggleOn) {
Text("Red")
Image(systemName: "paintpalette")
}
.tint(.red)
Toggle(isOn: $isToggleOn) {
Text("Orange")
Image(systemName: "paintpalette")
}
.tint(.orange)
SwiftUI 2.0
Using SwitchToggleStyle
You can now set a tint color for the on position only in SwiftUI 2.0:
Toggle(isOn: $isToggleOn) {
Text("Red")
Image(systemName: "paintpalette")
}
.toggleStyle(SwitchToggleStyle(tint: Color.red))
Toggle(isOn: $isToggleOn) {
Text("Orange")
Image(systemName: "paintpalette")
}
.toggleStyle(SwitchToggleStyle(tint: Color.orange))
SwiftUI 1.0
Using ToggleStyle
I created a new ToggleStyle to change the three colors of the Toggle (on color, off color, and the thumb).
struct ColoredToggleStyle: ToggleStyle {
var label = ""
var onColor = Color(UIColor.green)
var offColor = Color(UIColor.systemGray5)
var thumbColor = Color.white
func makeBody(configuration: Self.Configuration) -> some View {
HStack {
Text(label)
Spacer()
Button(action: { configuration.isOn.toggle() } )
{
RoundedRectangle(cornerRadius: 16, style: .circular)
.fill(configuration.isOn ? onColor : offColor)
.frame(width: 50, height: 29)
.overlay(
Circle()
.fill(thumbColor)
.shadow(radius: 1, x: 0, y: 1)
.padding(1.5)
.offset(x: configuration.isOn ? 10 : -10))
.animation(Animation.easeInOut(duration: 0.1))
}
}
.font(.title)
.padding(.horizontal)
}
}
Examples of Use
Toggle("", isOn: $toggleState)
.toggleStyle(
ColoredToggleStyle(label: "My Colored Toggle",
onColor: .green,
offColor: .red,
thumbColor: Color(UIColor.systemTeal)))
Toggle("", isOn: $toggleState2)
.toggleStyle(
ColoredToggleStyle(label: "My Colored Toggle",
onColor: .purple))
From the SwiftUI Book
Just use UIAppearance
APIs:
UISwitch.appearance().onTintColor = UIColor.blue
It'll of course by default change the appearance of all the instances of UISwitch
, as per UIAppearance
documentation.
NOTE: Tested as of Xcode 11 beta 5.
