ios SwiftUI点击网格中的图像并显示相邻帧(自闭症儿子的第一个应用程序)

所以这是我第一次尝试使用swift,对我来说也是一次学习的经历。我希望最终能为我的自闭症儿子使用这个非常简单的应用程序。我们的目标是在iPad的左手侧有一长串他可以选择的对象。如果他点击一个项目,我希望它出现在右手边,让他点击图像和声音播放命名它。
到目前为止,这是我所拥有的

我需要弄清楚如何将选择按钮的操作转换为将其显示在右侧。
其次,白色我已经想出了如何从网格播放声音,我想确保它可以从右边显示的项目播放。
下面是网格的代码,右边只是一个占位符图像。

如果有一个资源,我应该看看,我错过了,请只是指向那个方向。我很感激和反馈/帮助。太感谢了
我是如此的新,我甚至不知道如何描述我的问题,更不用说确定潜在的解决方案了。

感谢您发布代码。
您可能需要考虑尝试避免代码中的如此多的重复。例如,您可以使用一个函数来创建每个按钮。例如:

private func gridButton(imageName: String, sound: SoundManager.SoundOption) -> some View {
    Button(action: {SoundManager.instance.playsound(sound: sound)}, label: {
        Image(imageName)
            .resizable()
            .aspectRatio(contentMode: .fit)
            .cornerRadius(15)
    })
}

要在视图中的其他位置将所选项目显示为大图像,您只需要一个状态变量,每当按下按钮时可以更新该变量。例如:

struct SoundBootcamp: View {

    @State private var selectedImageName: String?

    private func gridButton(imageName: String, sound: SoundManager.SoundOption) -> some View {
        // see notes
    }

    var body: some View {
        VStack{
            Text("First Test Application")
                .lineLimit(1)
                .padding(10)
                .font(.system(size: 500))
                .minimumScaleFactor(0.01)
            HStack{
                ScrollView{
                    // content as before
                }
                VStack{

                    // Show the selected image here
                    if let selectedImageName {
                        Image(selectedImageName)
                            .scaledToFit()
                    }
                    Text("Example")
                }
                .frame(maxWidth: .infinity)
            }
        }
    }
}

然后可以更新创建按钮的函数,以在按钮回调中设置图像。大概是这样的:

private func gridButton(imageName: String, sound: SoundManager.SoundOption) -> some View {
    Button {
        SoundManager.instance.playsound(sound: sound)
        selectedImageName = imageName
    } label: {
        Image(imageName)
            .resizable()
            .aspectRatio(contentMode: .fit)
            .cornerRadius(15)
    }
}
  • EDIT* 在您的评论之后,如果您要使用该函数创建按钮,则第一个网格行将显示如下:
GridRow{
    gridButton(imageName: "airliner", sound: .cheetah)
    gridButton(imageName: "biplane", sound: .cheetah)
    gridButton(imageName: "cargoplane", sound: .cheetah)
    gridButton(imageName: "gliderplane", sound: .cheetah)
}

您可能还想考虑的是将不同的网格部分分解为单独的计算属性。这可能会使管理代码变得更容易。例如:

var aircraft: some View {
    VStack{
        Text("Aircraft")
            .font(.system(size: 48))
            .minimumScaleFactor(0.01)
        Grid{
            GridRow {
                gridButton(imageName: "airliner", sound: .cheetah)
                gridButton(imageName: "biplane", sound: .cheetah)
                gridButton(imageName: "cargoplane", sound: .cheetah)
                gridButton(imageName: "gliderplane", sound: .cheetah)
            }
            GridRow {
                // middle row
            }
            GridRow {
                // last row
            }
        }
        .padding()
    }
}

var animals: some View {
    // like aircraft
}

// + other sections in a similar way

滚动部分可以简化为:

ScrollView {
    VStack {
        aircraft
        animals
        letters
        numbers
        shapes
        colors
    }
}
