How to get selection text from UIWebView?

问题

, Hello, everyone.

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

This is a picture of UIWebview with UIMenuController.

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.

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];

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

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:

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