Ios SwiftUI 菜单中的内联水平按钮

这看起来目前只有UIKit(并且只有iOS 16+)可用，通过设置

menu.preferredElementSize = .medium

要将其添加到您的应用程序，您可以将UIMenu添加到UIButton，然后使用UIHostingController将其添加到您的SwiftUI应用程序.

下面是一个实现示例:

Subclass a UIButton个

class MenuButton: UIButton {
    
    override init(frame: CGRect) {
        super.init(frame: frame)

        let inspectAction = self.inspectAction()
        let duplicateAction = self.duplicateAction()
        let deleteAction = self.deleteAction()

        setImage(UIImage(systemName: "ellipsis.circle"), for: .normal)
        menu = UIMenu(title: "", children: [inspectAction, duplicateAction, deleteAction])
        menu?.preferredElementSize = .medium
        showsMenuAsPrimaryAction = true

    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    func inspectAction() -> UIAction {
        UIAction(title: "Inspect",
                 image: UIImage(systemName: "arrow.up.square")) { action in
           //
        }
    }
        
    func duplicateAction() -> UIAction {
        UIAction(title: "Duplicate",
                 image: UIImage(systemName: "plus.square.on.square")) { action in
           //
        }
    }
        
    func deleteAction() -> UIAction {
        UIAction(title: "Delete",
                 image: UIImage(systemName: "trash"),
            attributes: .destructive) { action in
           //
        }
    }

}

Create a 100 using UIViewRepresentable

struct Menu: UIViewRepresentable {
    func makeUIView(context: Context) -> MenuButton {
        MenuButton(frame: .zero)
    }
    
    func updateUIView(_ uiView: MenuButton, context: Context) {
    }
}

Works like a charm!个

struct ContentView: View {
    var body: some View {
        Menu()
    }
}
