如何从UIWebView获取选择文本？ [英] How to get selection text from UIWebView?

问题描述

，大家好。

我正在开发我的应用程序，该应用程序具有从网站发布文章的功能。

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

这是UIWebview与UIMenuController的图片。

This is a picture of UIWebview with UIMenuController.

当用户点击按钮时可能会出现事件。但我无法找到获取用户所选文本的方法。

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.

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

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

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];

我想在UIWebView上获取选择文本。
有没有人有想法或提示？

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

谢谢。

推荐答案

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来检索它：

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

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