因此,我的一位设计师设计师为我制作了一个密码生成器的模型,我将制作https://imgur.com/gallery/LZNNrWj,但我不知道如何使用SwiftUI(该按钮的渐变)在该渐变中进行编码是#41A5ED->#3099D8,并朝这个方向前进(见图)https://imgur.com/gallery/2rd7Iix,左上方是#41A5ED,右下方是#3099D8。我还想给此按钮一个像https://imgur.com/gallery/gEmBJ1w这样的底部阴影,并使其渐变与按钮相同。如果您对如何执行此操作有任何想法,请让我知道,因为我完全迷路了。

您可以这样做:
Button(action: createTask) {
Text(“MyButton“)
.color(.white)
.font(Font.system(size: 17))
.frame(height: 56)
.frame(minWidth: 0, maxWidth: .infinity)
.background(LinearGradient.actionButton, cornerRadius: 28)
.shadow() // configure shadow as you want
}
为了提高代码的可读性,我分别创建了渐变:
fileprivate extension LinearGradient {
static let actionButton = LinearGradient(gradient: Gradient(colors: [Color(“ActionGradientFirst”), Color(“ActionGradientSecond”)]),
startPoint: .topLeading,
endPoint: .bottomTrailing)
}
我在 Assets.xcasset
中声明的颜色ActionGradientFirst
和ActionGradientSecond

首先使用以下方法创建渐变,
let gradientLayer = CAGradientLayer()
gradientLayer.colors = [UIColor.red.cgColor, UIColor.black.cgColor]
gradientLayer.startPoint = CGPoint(x: 0, y: 0)
gradientLayer.endPoint = CGPoint(x: 1, y: 1)
gradientLayer.frame = view.bounds
然后只需将其应用于所需的任何视图,
view.layer.addSublayer(gradientLayer)
要添加阴影,
let shadowPath = UIBezierPath(rect: view.bounds)
view.layer.masksToBounds = false
view.layer.shadowColor = UIColor.grey.cgColor
view.layer.shadowOffset = CGSize(width: 0, height: 0.5)
view.layer.shadowOpacity = 0.2
view.layer.shadowPath = shadowPath.cgPath

有点晚了,但以防万一它对其他人有帮助。
ZStack{
LinearGradient(
gradient: .init(colors: [Color.white, Color.blue.opacity(0.66)]),
startPoint: .init(x: 0.0, y: 0.0),
endPoint: .init(x: 0.75, y: 0.75)
)
.mask(
RoundedRectangle(cornerRadius: 15)
.frame(width: 120, height: 45, alignment: .center)
.blur(radius: 10)
)
.padding(.top, 20)
Button(action: {}, label: {
Text("Siguiente")
.font(.custom("Avenir-Heavy", size: 20))
.padding(.top, 10)
.padding(.bottom, 10)
.padding(.leading, 16)
.padding(.trailing, 16)
})
.foregroundColor(.white)
.background(

}
