SwiftUI 渐变色

• 渐变探索

// 线性渐变
LinearGradient(gradient: Gradient(colors: [.red,.green]), startPoint: UnitPoint.topLeading, endPoint: UnitPoint.bottomTrailing)
            .frame( 200, height: 200)
// 角度渐变
AngularGradient(gradient: Gradient(colors: [.red,.green]), center: UnitPoint.center).frame( 200, height: 200)

// 半径渐变
RadialGradient(gradient: Gradient(colors: [.red,.green]), center: UnitPoint.center, startRadius:1, endRadius: 100)
            .frame( 200, height: 200)    }

LinearGradien：

使用LinearGradien绘制线形颜色渐变的背景。 示例代码：

Text("SwifUI Gradient")
    .font(.system(size: 36))
    .padding()
    .foregroundColor(.white)
    .background(LinearGradient(gradient: Gradient(colors: [.orange, .red, .purple]), startPoint: .topLeading, endPoint: .bottomTrailing))

}

AngularGradient：

使用AngularGradient绘制角度颜色渐变的背景。 示例代码：

VStack{
    Text("SwifUI Gradient")
    .font(.system(size: 36))
    .padding()
    .foregroundColor(.white)
    .background(AngularGradient(gradient: Gradient(colors: [.orange, .red, .purple]), center: UnitPoint(x: 0.5, y: 0.5), angle: Angle.init(degrees: -45)))

    Text("SwifUI Gradient")
    .font(.system(size: 36))
    .padding()
    .foregroundColor(.white)
    .background(AngularGradient(gradient: Gradient(colors: [.orange, .red, .purple]), center: UnitPoint(x: 0.5, y: 0.5), startAngle: Angle.init(degrees: 0), endAngle: Angle.init(degrees: 0)))

}

RadialGradient：

使用RadialGradient绘制径向颜色渐变的背景。 示例代码：

Text("SwifUI Gradient")
    .font(.system(size: 36))
    .padding()
    .foregroundColor(.white)
    .background(RadialGradient(gradient: Gradient(colors: [.orange, .red, .purple]), center: .init(x: 0.5, y: 0.5), startRadius: CGFloat(10), endRadius: CGFloat(120)))
