SwiftUI - 无法更改图像图标的颜色

问题描述：

我正在尝试构建自己的自定义标签栏视图，但在构建自定义按钮时，我无法更改 Image() 的颜色.

I am trying to build my own custom tabbar view, while building my custom buttons I am unable to change the color of Image().

struct TabBarButton: View {
      let title: String
      let icon: String


      var body: some View {
        return GeometryReader{ geometry in
           VStack {
            Image(self.icon)
              .resizable()
              .aspectRatio(contentMode: .fit)
              .frame(width: geometry.size.width/2, height: CGFloat(25))
              .foregroundColor(.white)

            Text(self.title)
                .font(.system(size: 8))
                .foregroundColor(Color.white)
          }
      }
    }

  }

我尝试过 foregroundColor(Color.white)、accentColor(Color.white) 和一些不同的颜色乘数.除了默认的黑色之外，是否有其他颜色没有其他原因?简单的修复只是获得白色图标，但希望我现在可以解决这个问题.

I have tried foregroundColor(Color.white), accentColor(Color.white), and some different color multipliers. Is there a reason the color isn't anything other than default black? Easy fix is just to get white icons but was hoping I could solve this for now.

答

我不确定你想达到什么目的，但可能你只需要模板渲染模式，比如

I'm not sure what are you trying to to achieve, but probably you just need template rendering mode, like

Image(self.icon)
    .renderingMode(.template)
    .foregroundColor(.white)
