SwiftUI—使用ViewModifier视图修饰符集成多个样式

struct ContentView : View {
    var body: some View {
        VStack(alignment: .center, spacing: 40){
            Image("avarta1").modifier(myImageStyle())
            Image("avarta2").modifier(myImageStyle())
            Image("avarta3").modifier(myImageStyle())
        }
        .padding()
    }
}
struct myImageStyle: ViewModifier {
    func body(content: Content) -> some View {
        content
            .frame(width: 200, height: 200, alignment: .leading)
            .cornerRadius(100)
            .clipped()
            .saturation(0.0)
    }
}
