伙计们！我有一个有点傻的问题。我想在 TableViewCell 中制作图标 like here 带有背景颜色和圆角。据我了解，我可以使用 Xcode 中定义的本机图标，但我无法更改背景，因为图标的大小与设置相比是错误的。 苹果是怎么做到的？他们制作图像还是可以通过 Xcode 和 Swift 本身来完成？谢谢
附：我将 TableViewController 与静态单元格一起使用，现在它看起来像 that
【问题讨论】：
UIImageView 中显示System Image？
标签： ios swift xcode uitableview icons
您几乎肯定会想要使用Custom 单元格样式而不是Basic。
添加UIView 以用作图标的“圆角”部分。为您的系统图像添加一个以该视图为中心的图像视图。添加标签。
基本方法（如您所述，使用静态表格视图）：
这是“圆形视图”的代码 - 配置为 @IBDesignable，因此您可以在 Storyboard 中看到它：
@IBDesignable
class RoundedView: UIView {
override init(frame: CGRect) {
super.init(frame: frame)
commonInit()
}
required init?(coder: NSCoder) {
super.init(coder: coder)
commonInit()
}
func commonInit() -> Void {
layer.cornerRadius = 8
layer.masksToBounds = true
}
}

【讨论】：
我认为最简单的方法是自己构建图标。只需使用 Sketch 或 Illustrator，在矩形顶部的 SF Pro Text 中添加一个新文本字段，然后将 SFSymbols 中的图标粘贴进去。将其导出为 PDF，您可以将其用作应用中的图标.
Here is a screenshot of the setup in Sketch.
