如何在 UIKit 中更改 SF Symbols 的图标颜色？

Question

在 中SwiftUI，您可以使用foregroundColor修饰符更改图标的颜色。所以我认为应该有一种方法可以改变UIKit. 我查阅了文档，并没有找到任何与之相关的内容。

现在可以吗？

let iconImage = UIImage(systemName: "chevron.right", 
    withConfiguration: UIImage.SymbolConfiguration(pointSize: 16, weight: .regular, scale: .medium))

Answer 1

使用以下代码更改 SFSymbols 图标颜色

let imageIcon = UIImage(systemName: "heart.fill")?.withTintColor(.red, renderingMode: .alwaysOriginal)
    imageView.image = imageIcon

前

后

Answer 2

用：

let icon = UIImageView(image: iconImage.withRenderingMode(.alwaysTemplate))
icon.tintColor = .red

Answer 3

一个小小的补充。如果对任何人有帮助，我很高兴。我们不仅可以组合不同的颜色，还可以组合不同的尺寸和重量。例如你可以这样做：

let colorsConfig = UIImage.SymbolConfiguration(paletteColors: [.white, .magenta])
let sizeConfig = UIImage.SymbolConfiguration(pointSize: 30, weight: .bold)
let image = UIImage(systemName: "plus.circle.fill", withConfiguration: colorsConfig.applying(sizeConfig))
button.setImage(image, for: .normal)

Answer 4

let image = UIImage(systemName: "arrow.up.circle.fill")?.withTintColor(.black, renderingMode: .alwaysOriginal)
button.setImage(image, for: .normal)

Answer 5

let iconImage = UIImage(systemName: "chevron.right",
                                            withConfiguration: UIImage.SymbolConfiguration(pointSize: 16, weight: .regular, scale: .medium))?.withTintColor(.systemGreen)

Answer 6

muteCall.setImage(UIImage(systemName: "mic.slash")?.withTintColor(.white, renderingMode: .alwaysOriginal), for: .normal)

将渲染设置为始终原始
