在 SwiftUI 中更改 TextEditor 的背景颜色 [英] Change background color of TextEditor in SwiftUI

问题描述

TextEditor 似乎有一个默认的白色背景.所以以下不起作用，它显示为 white 而不是定义的 red:

TextEditor seems to have a default white background. So the following is not working and it displayed as white instead of defined red:

var body: some View {
    TextEditor(text: .constant("Placeholder"))
        .background(Color.red)
}

是否可以将颜色更改为自定义颜色?

Is it possible to change the color to a custom one?

推荐答案

TextEditor 由 UITextView 支持.所以你需要先去掉 UITextView 的 backgroundColor 然后你可以设置任何 View 到 background>.

TextEditor is backed by UITextView. So you need to get rid of the UITextView's backgroundColor first and then you can set any View to the background.

struct ContentView: View {
    init() {
        UITextView.appearance().backgroundColor = .clear
    }

    var body: some View {
        List {
            TextEditor(text: .constant("Placeholder"))
                .background(Color.red)
        }
    }
}
