从一个渐变到另一个SwiftUI的动画过渡

import SwiftUI

struct ContentView: View {
    @State private var gradientColors: [Color] = [.red, .blue] // 初始渐变颜色
    @State private var isAnimating = false

    var body: some View {
        VStack {
            Rectangle()
                .fill(LinearGradient(gradient: Gradient(colors: gradientColors), startPoint: .leading, endPoint: .trailing))
                .frame(width: 200, height: 200)
                .animation(.easeInOut(duration: 1)) // 添加动画效果

            Button("切换渐变颜色") {
                withAnimation {
                    if isAnimating {
                        gradientColors = [.red, .blue] // 切换到初始渐变颜色
                    } else {
                        gradientColors = [.green, .yellow] // 切换到新的渐变颜色
                    }
                    isAnimating.toggle()
                }
            }
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
