ios - SwiftUI 中的堆叠 View

Question

我尝试使用 SwiftUI 将一个 View 传递到另一个 View ，但出现以下错误。

FormView.Type' 无法转换为 '(FormDetails) -> FormView'

这就是我正在尝试做的事情。我正在尝试创建一个“表单 View ”并在“吉他详细信息” View 中调用它。这是代码。任何帮助将不胜感激。

FormDetails.swift

import Foundation
> 
> struct FormDetails: Hashable {
>     let name: String
>      }
> 
> let formData: [FormDetails] = [
>     .init (name: "Simon Ambridge"),
>     .init (name: "Martin"),
>     .init (name: "Fender"),
>     .init (name: "Washburn"),
>     .init (name: "Gibson") ]

FormView.swift

import SwiftUI


struct FormView: View {

    var formView: FormDetails

    var body: some View {
        Form {
            Text(formView.name)
        }
    }
}
struct FormView_Previews: PreviewProvider {
    static var previews: some View {
        FormView(formView: formData[0])
    }
}

GuitarDetails.swift

import SwiftUI

struct GuitarDetails: View {

    var selectedGuitar: Guitar

    @State private var zoomed = false

    var body: some View {
        NavigationView {
            VStack {
                Image(selectedGuitar.imageName)
                    .resizable()
                    .aspectRatio(contentMode: zoomed ? .fill: .fit)
                    .onTapGesture { withAnimation {self.zoomed.toggle()}}
            }.navigationBarTitle(Text(selectedGuitar.name), displayMode: .inline)
            FormView() ***<----FormView.Type' is not convertible to '(FormDetails) -> FormView'***
        }
    }
}

struct GuitarDetails_Previews: PreviewProvider {
    static var previews: some View {
        GuitarDetails(selectedGuitar: guitars[2])
    }
}

就像@Sweeper所说，您需要在创建FormView时设置formDetails属性。将值传递到其构造函数中。
