如何从UIWebView获取选择文本？

, Hello, everyone.

, 大家好。

I'm developing my app which has a feature to post article from website.

我正在开发我的应用程序,它具有从网站发布文章的功能。

This is a picture of UIWebview with UIMenuController.

这是UIWebview与UIMenuController的图片。

It was possible to get event when user tap the button. but I can't find the way to get the text the user selected.

当用户点击按钮时,可以获得事件。但我找不到获取用户所选文本的方法。

In UITextView case, it has 'selectedRange' property, so it is easy to get selection text.

在UITextView案例中,它具有'selectedRange'属性,因此很容易获得选择文本。

UIMenuItem *facebookMenuItem = [[UIMenuItem alloc] initWithTitle:@"Facebook" action:@selector(facebookMenuItemTapped:)];
UIMenuItem *twitterMenuItem = [[UIMenuItem alloc] initWithTitle:@"Twitter" action:@selector(twitterMenuItemTapped:)];

[UIMenuController sharedMenuController].menuItems = [NSArray arrayWithObjects: facebookMenuItem, twitterMenuItem, nil];

[twitterMenuItem release];
[facebookMenuItem release];

I would like to get the selection text on UIWebView. Does anybody have an idea or hint?

我想在UIWebView上获取选择文本。有人有想法或暗示吗?

Thanks.

Or if you donʾt want to mess with Javascript you can just copy the selection to the pasteboard and then retrieve it by running:

或者如果你不想搞乱Javascript,你可以将选择复制到粘贴板,然后通过运行检索它:

    [[UIApplication sharedApplication] sendAction:@selector(copy:) to:nil from:self forEvent:nil];
    NSString *text =  [UIPasteboard generalPasteboard].string;
