我有一个包含按钮的视图。带有按钮的视图是从 forEach 循环创建的。出于某种原因,只有一些按钮可以点击,而其他按钮则不能。
父视图包含 NavigationView、NavigationView 内部的滚动视图、滚动视图内部的lazyVStack、lazyVStack 中的 forEachloop 以及包含按钮的子视图。
struct ContentView: View {
let peoples:[Person] = Bundle.main.decode("data.json")
var body: some View {
let columns = [
GridItem(.flexible(minimum: 300), spacing: 10)
]
NavigationView {
ScrollView(.vertical) {
LazyVStack {
ForEach(peoples, id: \.self) { person in
PersonView(name: person.Name, age: person.Age)
}
}
.navigationTitle("A list of people")
.navigationViewStyle(DefaultNavigationViewStyle())
.padding()
}
}
}
}
子视图如下。我怀疑滚动视图正在窃取用户输入,但我不确定为什么或如何克服它。有些按钮是可粘贴的,有些则不是。
struct PersonView: View {
@Environment(\.colorScheme) var colorScheme
var name: String
var age: Int
var body: some View {
VStack(alignment:.leading) {
Image("randoPerson")
.resizable()
.scaledToFill()
.frame(minWidth: nil, idealWidth: nil,
maxWidth: UIScreen.main.bounds.width, minHeight: nil,
idealHeight: nil, maxHeight: 300, alignment: .center)
.clipped()
VStack(alignment: .leading, spacing: 6) {
Text("name")
.fontWeight(.heavy)
.padding(.leading)
Text("Age \(age)")
.foregroundColor(Color.gray)
.padding([.leading,.bottom])
Button(action: { print("I was tapped") }) {
HStack {
Image(systemName: "message.fill")
.font(.title)
.foregroundColor(.white)
.padding(.leading)
Text("Message them")
.font(.subheadline)
.foregroundColor(.white)
.padding()
}
.background(Color.blue)
}
.padding()
}
.background(Color(UIColor.systemBackground).cornerRadius(15))
.shadow(color:colorScheme == .dark
? Color.white.opacity(0.2)
: Color.black.opacity(0.2),
radius: 7, x: 0, y: 2)
}
}
}
