Radio Buttons group in SwiftUI
Radio Buttons group in SwiftUI, is not hard to implement classic radio button group in your SwiftUI. Though this project is in very early stage, I will work on this in coming days to enhance its features.
Installation: Add RadioButtonGroup.swift in your SwiftUI project.
Usages: Create model class, must conform to RadioModelable protocol
class RadioModel: RadioModelable {
var id: Int
var isChecked: Bool
var label: String
required init(id: Int, isChecked: Bool, label: String) {
self.id = id
self.isChecked = isChecked
self.label = label
}
}Create data provider class, must conform to RadioDataProviding protocol
class DataProvider<T>: RadioDataProviding where T: RadioModelable {
@Published var items: [RItem] = []
init() {
self.items = getItems()
}
func getItems() -> [T] {
return [T(id: 1, isChecked: true, label: "Radio 1"),
T(id: 2, isChecked: false, label: "Radio 2"),
T(id: 3, isChecked: false, label: "Radio 3")]
}
func toggle(id: Int) {
for var item in self.items {
if item.id == id {
item.isChecked = true
} else {
item.isChecked = false
}
}
self.objectWillChange.send()
}
}Finally add in your view
struct ContentView: View {
var body: some View {
SRadioButtonViewGroup(dataProvider: DataProvider<RadioModel>(), selectedItem: getSelectedItemLabel)
}
func getSelectedItemLabel<T>(item: T) {
print("selected item : \((item as! RadioModel).label)")
}
}Preview
