部分解决方案
为ActionSheet创建自定义配置器:
import SwiftUI
struct ActionSheetConfigurator: UIViewControllerRepresentable {
var configure: (UIAlertController) -> Void = { _ in }
func makeUIViewController(context: UIViewControllerRepresentableContext<ActionSheetConfigurator>) -> UIViewController {
UIViewController()
}
func updateUIViewController(
_ uiViewController: UIViewController,context: UIViewControllerRepresentableContext<ActionSheetConfigurator>) {
if let actionSheet = uiViewController.presentedViewController as? UIAlertController,actionSheet.preferredStyle == .actionSheet {
self.configure(actionSheet)
}
}
}
struct ActionSheetCustom: ViewModifier {
func body(content: Content) -> some View {
content
.background(ActionSheetConfigurator { action in
// change the text color
action.view.tintColor = UIColor.black
})
}
}
在视图中,在 .actionSheet 修饰符之后,添加自定义修饰符,如下所示:
.actionSheet(isPresented: $viewModel.isCustomItemSelected) {
ActionSheet(
title: Text("Add Item"),message: Text("Wich item would you like to add?"),buttons: [
.default(Text("Todo")),.default(Text("Event")),.cancel(Text("Cancel"))
])
}
.modifier(ActionSheetCustom())
我没有弄清楚如何更改背景颜色或如何进行主要自定义。我确定我们应该在要更改颜色的 action 对象上进行操作。
