SwiftUI—使用Stepper步进器在小范围内进行数值的精确调整

struct ContentView : View {
     @State var temperature: Double = 0 //和步进器视图进行数据绑定
       var body: some View {
           VStack {
                Stepper(onIncrement: { //添加一个步进器视图
                    self.temperature += 1 //递增事件
                }, onDecrement: {
                    self.temperature -= 1 //递减事件
                }, label: { Text("Temperature: \(Int(temperature))") }) //数值标签
                Stepper(onIncrement: {
                    self.temperature += 1
                }, onDecrement: {
                    self.temperature -= 1
                }, onEditingChanged: { (item) in
                    print(item)
                }, label: { Text("Temperature: \(Int(temperature))") })
       }.padding()
    }
}
