Question

我以这种方式在uiviewconroller中显示UIMenuController：

在我班上：

override open func canBecomeFirstResponder() -> Bool {
    return true
}

open override func canPerformAction(_ action: Selector, withSender sender: Any) -> Bool {

    //here I check for my custom action, else return false
    return false
}

然后显示我使用：

//Make this as first responder
    self.becomeFirstResponder()

    ///Build menu
    let menu = UIMenuController.shared
    ///Set item and anchor point, and showit
    menu.menuItems  = itemsToAdd
    menu.setTargetRect(CGRect(x: 0, y: 5, width: bubbleNode.view.bounds.size.width, height: bubbleNode.view.bounds.size.height), in: bubbleImageNode.view)
    menu.setMenuVisible(true, animated: true)

问题在于我在设备中显示我的自定义项目，还有：“拼写，说话，斑点句子，ecc ......”我该如何禁用它？

Answer 1

覆盖canPerformAction并为每个特定操作处理它。它非常适合我。

 override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {

        var canPerform = super.canPerformAction(action, withSender: sender)

        if (action == "your action to restrict") {
              canPerform = false
        }

        return canPerform
    }

Answer 2

好的，问题是＆＃34;辅助功能＆＃34;选项＆＃34;说出选择＆＃34;在我的设备中，如果我禁用它，我只会看到自定义项目，但在其他应用程序中，我只看到启用了此选项的自定义项目！

Answer 3

class TextViewWithCopyAction: UITextView {

    override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
        if action == #selector(copy(_:)){
            return true
        } else {
            return false
        }
        
    }
}

使用：

let textView: TextViewWithCopyAction = {
    let textView = TextViewWithCopyAction()
    textView.backgroundColor = .white
    return textView
}()

如果您在UIMenuController中看到来自设备的说选项，请转到：

设置->辅助功能->语音->语音

选择并禁用它。自动讲话选项将从菜单中删除。

UIMenuController不隐藏系统项
