ios - 在 objective-c 中选择文本时，如何防止出现复制按钮？

Question

我不希望在选择文本时出现“复制/定义”按钮。 我怎样才能在 objective-c 中做到这一点？

更新:我想在 UIWebView 中执行此操作

Answer 1

The easiest way to disable pasteboard operations is to create a subclass of UITextView that overrides the canPerformAction:withSender: method to return NO for actions that you don't want to allow:

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
    if (action == @selector(paste:))
        return NO;
    return [super canPerformAction:action withSender:sender];
}

另见 UIResponder
