【问题描述】：
我在 swiftui 中的 geometryReader 内的 Vstack 内的 ZStack 内的 Vstack 内的 Hstack 内嵌入了一个按钮，该按钮不会被点击。我在里面放了一个打印语句，每当我尝试点击按钮时，打印语句都不会打印。有谁可以帮我离开这里吗？谢谢。这是我的代码：
struct DetailedGroupView: View {
@State var actrualImage: Image?
@State var title = "title"
@State var description = "description"
@State var sgName = "sgName"
@State var membersCount = 0
@Environment(\.presentationMode) var presentationMode
var body: some View {
GeometryReader{ geo in
VStack{
ZStack{
(self.actrualImage ?? Image("earthPlaceholder"))
.resizable()
.aspectRatio(contentMode: .fill)
VStack{
Spacer()
HStack{
//This button doesn't work
Button(action: {
print("Button Tapped")
self.presentationMode.wrappedValue.dismiss()
}, label: {
Image(systemName: "chevron.left").foregroundColor(.white)
}).padding()
Text(self.title)
.font(.largeTitle)
.fontWeight(.bold)
.multilineTextAlignment(.leading)
.foregroundColor(.white)
.padding()
.minimumScaleFactor(0.5)
Spacer()
}
HStack{
Text(self.description)
.font(.custom("Open Sans", size: 18))
.fontWeight(.ultraLight)
.multilineTextAlignment(.leading)
.foregroundColor(.white)
.padding()
Spacer()
}
Spacer()
HStack{
Image(systemName: "person.2.fill").foregroundColor(.white).padding(.leading)
Text("\(self.membersCount)")
.font(.custom("Open Sans", size: 12))
.fontWeight(.semibold)
.foregroundColor(.white)
Spacer()
Text(self.sgName)
.font(.custom("Open Sans", size: 12))
.fontWeight(.semibold)
.foregroundColor(.white)
.padding()
}.padding()
}.frame(width: geo.size.width, height: 294)
}.frame(width: geo.size.width, height: 294)
.clipShape(RoundedRectangle(cornerRadius: 12))
.edgesIgnoringSafeArea(.top)
Spacer()
ScrollView(showsIndicators: false){
VStack{
Spacer()
}.onAppear{
self.actrualImage = Image("globePlaceholder")
}
}
}
}.navigationBarBackButtonHidden(true)
}
}
