Initializer

init(value:in:label:)

Creates a gauge showing a value within a range and describes the gauge’s purpose and current value.

Declaration 宣言

init<V>(value: V, in bounds: ClosedRange<V> = 0...1, label: () -> Label) where CurrentValueLabel == EmptyView, BoundsLabel == EmptyView, MarkedValueLabels == EmptyView, V : BinaryFloatingPoint

Parameters パラメータ

value: The value to show in the gauge.
bounds: The range of the valid values. Defaults to 0...1.
label: A view that describes the purpose of the gauge.

Discussion 議論

Use this modifier to create a gauge that shows the value at its relative position along the gauge and a label describing the gauge’s purpose. In the example below, the gauge has a range of 0...1, the indicator is set to 0.4, or 40 percent of the distance along the gauge:

struct SimpleGauge: View {
    @State private var batteryLevel = 0.4


    var body: some View {
        Gauge(value: batteryLevel) {
            Text("Battery Level")
        }
    }
}

A linear gauge that shows an indicator at 40 percent along the length

init<V>(value: V, in: ClosedRange<V>, label: () -> Label, currentValueLabel: () -> CurrentValueLabel)

Creates a gauge showing a value within a range and that describes the gauge’s purpose and current value.

init<V>(value: V, in: ClosedRange<V>, label: () -> Label, currentValueLabel: () -> CurrentValueLabel, markedValueLabels: () -> MarkedValueLabels)

Creates a gauge representing a value within a range.

init<V>(value: V, in: ClosedRange<V>, label: () -> Label, currentValueLabel: () -> CurrentValueLabel, minimumValueLabel: () -> BoundsLabel, maximumValueLabel: () -> BoundsLabel)

Creates a gauge showing a value within a range and describes the gauge’s current, minimum, and maximum values.

init<V>(value: V, in: ClosedRange<V>, label: () -> Label, currentValueLabel: () -> CurrentValueLabel, minimumValueLabel: () -> BoundsLabel, maximumValueLabel: () -> BoundsLabel, markedValueLabels: () -> MarkedValueLabels)

Creates a gauge representing a value within a range.
