我一直在尝试在SwiftUI中创建表单,但是由于使用“ Form()”的局限性,我改为选择使用包含按钮的ForEach循环创建ScrollView。当我运行该项目并尝试单击按钮时,它将单击不正确的按钮,除非我滚动视图。我是SwiftUI的新手,但无法弄清楚。
我尝试制作不同尺寸的ScrollView,但似乎没有关联
struct DropDown: View {
var datos: [String]
var categoria: String
@State var titulo: String = "Seleccione"
@State var expand = false
var body: some View {
VStack {
Text(categoria).fontWeight(.heavy).foregroundColor(.white)
HStack {
Text(titulo).fontWeight(.light).foregroundColor(.white)
Image(systemName: expand ? "chevron.up" : "chevron.down").resizable().frame(width: 10,height: 6).foregroundColor(.white)
}.onTapGesture {
self.expand.toggle()
}
if expand {
ScrollView(showsIndicators: true) {
ForEach(0..<self.datos.count){ nombre in
Button(action: {
print(self.datos[nombre])
self.titulo = self.datos[nombre]
self.expand.toggle()
diccionarioDatos[self.categoria] = self.titulo
print(diccionarioDatos)
}) {
Text(self.datos[nombre]).foregroundColor(.white)
}
}
}
.frame(maxHeight: 150)
.fixedSize()
}
}
.padding()
.background(LinearGradient(gradient: .init(colors: [.blue,.green]),startPoint: .top,endPoint: .bottom))
.cornerRadius(20)
.animation(.spring())
}
}
I clicked on "2018" under "Modelo" and "2015" got selected for some reason
