如何在列表中更改ListStyle [英] How to change ListStyle in List

问题描述

在SwiftUI中List似乎具有一个名为ListStyle的属性.

In SwiftUI List Appears to have a property called ListStyle.

如何更改列表的样式

struct ListView : View {
var body: some View {
    NavigationView {
    List(Item.create().identified(by: \.id)){ row in
        NavigationButton(destination: DetailsView(item: row)) {
            RowView(item: row)
        }
    }
    .listStyle(StaticMember<PlainListStyle.Member>.self) // error here
    .foregroundColor(.red)
    .navigationBarTitle(Text("List View"))
    .statusBar(hidden: false)
    }
  }
}

ListStyle协议的符合方是

1. CarouselListStyle
2. DefaultListStyle
3. GroupedListStyle
4. PlainListStyle
5. SidebarListStyle

但是我在努力为列表设置新样式而苦苦挣扎 像这样使用它

However i am struggling trying to set a new style for the list using it like this

.listStyle(StaticMember<PlainListStyle.Member>.self)

我尝试了很多方法，但是确认ListStyle的每种样式都是struct，就像它们不是枚举值一样

I have tried so many ways, but each style confirming to the ListStyle is struct, like they're not enumerated values

任何人都有一个想法如何更改List的样式?

Anyone have an idea how to change the style of List ?

Xcode错误

无法将类型"StaticMember.Type"(也称为"StaticMember> .Type")的值转换为预期的参数类型"StaticMember< __>"

Cannot convert value of type 'StaticMember.Type' (aka 'StaticMember>.Type') to expected argument type 'StaticMember<_>'

使用:.listStyle(StaticMember<PlainListStyle.Member>)

Xcode错误

无法将类型'(StaticMember).Type'(又名'StaticMember> .Type')的值转换为预期的参数类型'StaticMember< __>'

Cannot convert value of type '(StaticMember).Type' (aka 'StaticMember>.Type') to expected argument type 'StaticMember<_>'

使用:.listStyle(StaticMember<PlainListStyle()>)或.listStyle(StaticMember<PlainListStyle.self>)

Xcode错误

'>'不是后缀一元运算符

'>' is not a postfix unary operator
