我正在使用Xcode 9和iOS 11,谷歌搜索禁用复制粘贴选项,但未成功。
下面是我尝试过的:
override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
if action == #selector(UIResponderStandardEditActions.paste(_:)) || action == #selector(UIResponderStandardEditActions.copy(_:)) {
return false
}
return true
}
并且还尝试了:
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。但是没有成功。其实我不想在菜单上方显示,然后长按
UITextField
。 最佳答案
经过测试并在iOS 12中工作:
override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool
{
if action == #selector(self.paste(_:))
||
action == #selector(self.copy(_:))
||
action == #selector(self.cut(_:))
||
action == #selector(self.select(_:))
||
action == #selector(self.selectAll(_:))
{
return false
}
return super.canPerformAction(action, withSender: sender)
}
