静态方法“buildBlock”要求“Button<Any>.Type”符合“View”

Question

斯威夫伊新手。我该如何解决这个问题？

struct ContentView: View {
    var body: some View {
        HStack {
            VStack {
                Text("Hello World")
                .frame(maxWidth: .infinity, maxHeight: .infinity)
            }
            VStack {
                Button(action:  {
                    self.volumeCheck()
                }) {
                    Image("chimes")
                      .renderingMode(Image.TemplateRenderingMode?.init(Image.TemplateRenderingMode.original))

                }
                Button(action: {
                    self.volumeCheck()
                }) {
                    Text("Click chimes to test volume")
                }
            }
        }

    }

    func volumeCheck() {

    }
}

Answer 1

我在 Xcode 13.1 中遇到了同样的错误（静态方法“buildBlock”要求“Button”符合“View”）。并非所有项目都如此，只是部分项目如此。令人惊讶的是，对我有帮助的是按以下方式使用 Button（只需加上 SwiftUI 前缀）：

SwiftUI.Button

您必须将 UIKIT 集成到您的项目中，并使 UIButton 符合 UIViewRepresentable 和 UIViewControllerRepresentable 让您可以将现有的 UIKit 组件移植到 SwiftUI。最简单的示例之一是 UIButton，在撰写本文时，它没有\xe2\x80\x99t 相应的 SwiftUI 组件。

struct ButtonView: UIViewRepresentable {\n\n\nfunc makeUIView(context: UIViewRepresentableContext<ButtonView>) -> UIButton {\n    return UIButton(frame: sampleFRame)\n}\n\nfunc updateUIView(_ uiView: UIButton, context: UIViewRepresentableContext<ButtonView>) {\n    \n}\n\n}\n

 var body: some View {\n    VStack {\n        ButtonView().onTapGesture {\n                print("Tapped")\n        }\n        Spacer()\n    }\n}\n
