Horizontal wheel picker for SwiftUI
## Requirements
iOS 13.0+
## Installation
### [CocoaPods](https://cocoapods.org)
```ruby
pod 'SwiftUIWheelPicker'
```
### Import
```swift
import SwiftUIWheelPicker
```
## Getting Started
### Basic use
```swift
@State var indexBasic: Int = 5
@State var items: [Int] = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
...
SwiftUIWheelPicker($indexBasic, items: $items) { value in
GeometryReader { reader in
Text("\(value)")
.frame(width: reader.size.width, height: reader.size.height, alignment: .center)
}
}
.frame(width: geometry.size.width - 40, height: 40, alignment: .center)
.padding(.top, 10)
```
### With Visible Count
```swift
SwiftUIWheelPicker($indexRatio, items: $items) { value in
GeometryReader { reader in
Text("\(value)")
.frame(width: reader.size.width, height: reader.size.height, alignment: .center)
}
}
.width(.Ratio(0.1))
```
```swift
public enum WidthOption {
case VisibleCount(Int) // How many items to show on the display
case Fixed(CGFloat) // to a fixed width
case Ratio(CGFloat) // From the width of the view to the ratio
}
```
### With Alpha
```swift
SwiftUIWheelPicker($indexAlpha, items: $items) { value in
GeometryReader { reader in
Text("\(value)")
.frame(width: reader.size.width, height: reader.size.height, alignment: .center)
}
}
.scrollAlpha(0.1)
```
### With Scale
```swift
SwiftUIWheelPicker($indexScale, items: $items) { value in
GeometryReader { reader in
Text("\(value)")
.frame(width: reader.size.width, height: reader.size.height, alignment: .center)
}
}
.scrollScale(0.4)
```
### With Gradient
```swift
SwiftUIWheelPicker($indexGradient, items: $items) { value in
GeometryReader { reader in
Text("\(value)")
.frame(width: reader.size.width, height: reader.size.height, alignment: .center)
}
}
.edgeLeft(AnyView(
LinearGradient(gradient: Gradient(colors: [Color.gray.opacity(0.4), Color.white.opacity(0)]), startPoint: .leading, endPoint: .trailing)
), width: .Ratio(0.2))
.edgeRight(AnyView(
LinearGradient(gradient: Gradient(colors: [Color.white.opacity(0), Color.gray.opacity(0.4)]), startPoint: .leading, endPoint: .trailing)
), width: .Ratio(0.2))
```
### Center indicator
```swift
SwiftUIWheelPicker($indexIndicator, items: $items) { value in
GeometryReader { reader in
Text("\(value)")
.frame(width: reader.size.width, height: reader.size.height, alignment: .center)
}
}
.centerView(AnyView(
HStack(alignment: .center, spacing: 0) {
Divider()
.frame(width: 1)
.background(Color.gray)
.padding(EdgeInsets(top: 6, leading: 0, bottom: 6, trailing: 0))
.opacity(0.4)
Spacer()
Divider()
.frame(width: 1)
.background(Color.gray)
.padding(EdgeInsets(top: 6, leading: 0, bottom: 6, trailing: 0))
.opacity(0.4)
}
), width: .Fixed(40))
```
### Selected Value
```swift
@State var indexValue: Int = 5
@State var items: [Int] = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
Text("Selected Value : \(indexValue)").font(Font.title)
SwiftUIWheelPicker($indexValue, items: $items) { value in
GeometryReader { reader in
Text("\(value)")
.frame(width: reader.size.width, height: reader.size.height, alignment: .center)
.background(value % 2 == 0 ? Color.blue.opacity(0.4) : Color.green.opacity(0.4))
}
}
```
### Scroll To
```swift
HStack(alignment: .bottom, spacing: 20) {
Text("Scroll To ").font(Font.title)
Spacer()
Button("First") {
indexScrollTo = 0
}
Button("Center") {
indexScrollTo = items.count / 2
}
Button("Last") {
indexScrollTo = items.count - 1
}
}
SwiftUIWheelPicker($indexScrollTo, items: $items) { value in
GeometryReader { reader in
Text("\(value)")
.frame(width: reader.size.width, height: reader.size.height, alignment: .center)
.background(value % 2 == 0 ? Color.blue.opacity(0.4) : Color.green.opacity(0.4))
}
}
```
