在SwiftUI中的另一个视图中设置@State变量

struct ContentView: View {
    @State private var counter = 0
    
    var body: some View {
        // 视图内容
    }
}

struct AnotherView: View {
    @Binding var counter: Int
    
    var body: some View {
        // 视图内容
    }
}

struct ContentView: View {
    @State private var counter = 0
    
    var body: some View {
        VStack {
            Text("Counter: \(counter)")
            
            AnotherView(counter: $counter)
        }
    }
}
