你如何为 中的标题设置自定义字体UIContextualAction?
我试过了,UIAppearance但没有任何运气......
干杯! :)

我找到了一种通过使用图像属性而不是标题来做到这一点的方法......
标准字体(删除/重命名)
自定义字体(删除/重命名)
要创建标签图像,我有这个扩展:
extension UIImage {
/// This method creates an image of a view
convenience init?(view: UIView) {
// Based on https://stackoverflow.com/a/41288197/1118398
let renderer = UIGraphicsImageRenderer(bounds: view.bounds)
let image = renderer.image { rendererContext in
view.layer.render(in: rendererContext.cgContext)
}
if let cgImage = image.cgImage {
self.init(cgImage: cgImage, scale: UIScreen.main.scale, orientation: .up)
} else {
return nil
}
}
}

然后我只是:
override func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let action = UIContextualAction(style: .destructive, title: nil) { action, view, completion in
// Your swipe action code!
}
let label = UILabel()
label.text = // Your swipe action text!
label.font = // Your custom font!
label.sizeToFit()
action.image = UIImage(view: label)
return UISwipeActionsConfiguration(actions: [action])
}

我最近找到了一种方法,通过使用按钮 titleLabel 而不是图像属性来执行此操作,这样您就可以保持对文本和图像进行操作的能力。
正如你将看到的,我们需要做一些尴尬的事情......
func tableView(_ tableView: UITableView, willBeginEditingRowAt indexPath: IndexPath) {
if #available(iOS 13.0, *) {
for subview in tableView.subviews {
if NSStringFromClass(type(of: subview)) == "_UITableViewCellSwipeContainerView" {
for swipeContainerSubview in subview.subviews {
if NSStringFromClass(type(of: swipeContainerSubview)) == "UISwipeActionPullView" {
for case let button as UIButton in swipeContainerSubview.subviews {
button.titleLabel?.font = .systemFont(ofSize: 12)
}
}
}
}
}
} else {
for subview in tableView.subviews {
if NSStringFromClass(type(of: subview)) == "UISwipeActionPullView" {
for case let button as UIButton in subview.subviews {
button.titleLabel?.font = .systemFont(ofSize: 12)
}
}
}
}
}
