我正在使用Xcode 9和iOS 11,谷歌搜索禁用复制粘贴选项,但没有成功。
低于我的尝试:
override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
if action == #selector(UIResponderStandardEditActions.paste(_:)) || action == #selector(UIResponderStandardEditActions.copy(_:)) {
return false
}
return true
}
还尝试过:
override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
if action == #selector(UIResponderStandardEditActions.paste(_:)) || action == #selector(paste(_:)) || action == #selector(cut(_:)) || action == #selector(selectAll(_:)) || action == #selector(select(_:)){
return false
}
return true
}
并尝试了Stackoverflow的许多其他代码。但没有成功。实际上我不想显示上面的菜单,然后长按UITextField
。

经过测试并在iOS 12中正常工作

The above exception was the direct cause of the following exception:

以下5条代码对我有用
override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
OperationQueue.main.addOperation {
UIMenuController.shared.setMenuVisible(false, animated: false)
}
return super.canPerformAction(action, withSender: sender)
}
