SwiftUI-如何更改视图的背景颜色? [英] SwiftUI - How do I change the background color of a View?

问题描述

我开始尝试SwiftUI，但令我惊讶的是，更改View的背景颜色似乎并不简单.您如何使用SwiftUI做到这一点?

I'm beginning to try out SwiftUI and I'm surprised that it doesn't seem to be straightforward to change the background color of a View. How do you do this using SwiftUI?

推荐答案

您可以执行以下操作:

.background(Color.black)

围绕您的观点.

例如来自默认模板(我将其包含在一个组中):

eg. from the default template (I am encompassing it around a Group):

    var body: some View {
        VStack {
          Text("Hello SwiftUI!")
        }
       .background(Color.black)
    }

要为其添加一些不透明度，还可以添加.opacity方法:

To add some opacity to it, you can add the .opacity method as well:

.background(Color.black.opacity(0.5))

您还可以通过CMD使用视图的检查元素+单击视图，然后单击Show SwiftUI Inspector> Background>您的颜色

You can also make use of the inspect element of the view by CMD + click on the View and clicking Show SwiftUI Inspector > Background > Your Color
