更改 SwiftUI 中的 UITableViewCell 背景颜色

Question

I use a list to display a dynamic number of custom views. See code.

 @State var coins : [Coin]

var coinList : some View {
        List {
            ForEach(0..<coins.count, id: \.self) { i in
                    CoinEntry(coin: coins[i])
                }.onDelete(perform: { indexSet in
                    self.coins.remove(atOffsets: indexSet)
                })
        }.frame(width: UIScreen.main.bounds.width)
    }

After that, I had this list.

After that I modified the list like this.

UITableView.appearance().backgroundColor = UIColor.clear
UITableViewCell.appearance().backgroundColor = UIColor.clear

The bottom of the list has now changed to clear, but the cells are still white.

If I edit it like this:

CoinEntry(coin: coins[i]).background(MAIN_DARK_GRAY)

The list looks like this:

Hope someone can help!

Change background color of a view by simply adding.background property

var coinList : some View {
    List {
        ForEach(0..<coins.count, id: \.self) { i in
                CoinEntry(coin: coins[i]).background(MAIN_DARK_GRAY)
            }.onDelete(perform: { indexSet in
                self.coins.remove(atOffsets: indexSet)
            })
    }.frame(width: UIScreen.main.bounds.width).background(MAIN_DARK_GRAY)
}

Or you can use listRowBackground property

var coinList : some View {
    List {
        ForEach(0..<coins.count, id: \.self) { i in
                CoinEntry(coin: coins[i])
            }.onDelete(perform: { indexSet in
                self.coins.remove(atOffsets: indexSet)
            })
    }.frame(width: UIScreen.main.bounds.width).listRowBackground(MAIN_DARK_GRAY)
}
