我一直在尝试在 SwiftUI 中获得这种凹陷效果,但没有任何效果。我尝试了 Shadow(color:radius:x:y:) 修饰符,但它在符号的外部应用了阴影。您能告诉我是否还有其他 API 或技巧可以实现此目的吗? 谢谢你!
喜欢凹凸效果,让我想起了 iOS 6。关键是finding
inverseMask
,然后我玩了一下,想出了这个:
import SwiftUI
extension View {
// https://www.raywenderlich.com/7589178-how-to-create-a-neumorphic-design-with-swiftui
func inverseMask<Mask>(_ mask: Mask) -> some View where Mask: View {
self.mask(mask
.foregroundColor(.black)
.background(Color.white)
.compositingGroup()
.luminanceToAlpha()
)
}
}
struct DebossTest: View {
static var lightPurple = UIColor(red: 212/255, green: 206/255, blue: 247/255, alpha: 1)
var body: some View {
ZStack {
Color(uiColor: DebossTest.lightPurple)
MyButton()
.font(.system(size: 144))
}
}
}
struct MyButton: View {
static var darkPurple = UIColor(red: 140/255, green: 134/255, blue: 211/255, alpha: 1)
let trashName = "trash.fill"
var body: some View {
ZStack {
// the darker inset image
Image(systemName: trashName)
.foregroundColor(Color(uiColor: MyButton.darkPurple))
// black inner shadow
Rectangle()
.inverseMask(Image(systemName: trashName))
.shadow(color: Color.black, radius: 1, x: 0, y: 1)
.mask(Image(systemName: trashName))
.clipped()
// white bottom edges
Image(systemName: trashName)
.shadow(color: Color.white, radius: 1, x: 0, y: 1)
.inverseMask(Image(systemName: trashName))
}
.frame(width: 185, height: 140)
}
}
struct DebossTest_Previews: PreviewProvider {
static var previews: some View {
DebossTest()
}
}
malhal的答案很完美,但我的做法与他的做法不同。我的代码可以通过图像更新剪辑视图,通常我们可以使用形状来完成,但这是另一天的事,这是我的方式:
struct ContentView: View {
var body: some View {
Color.yellow
.overlay(
Circle()
.fill(Color.black)
.frame(width: 100, height: 100)
.opacity(0.1)
.overlay(
ZStack {
Circle()
.stroke(Color.black, lineWidth: 3)
.blur(radius: 5)
ZStack {
Image(systemName: "info")
.resizable()
.scaledToFit()
.foregroundColor(Color.black)
.blur(radius: 5)
.opacity(0.5)
Image(systemName: "info")
.resizable()
.scaledToFit()
.foregroundColor(Color.yellow)
}
.padding()
}
)
.clipShape(Circle())
)
}
}
