This is great! Any plans to add support for links and anchor tags? about gonmarkupparser

Hi,
Can you give me more information and an example ?
Thanks for your interest ;)

For example, to process a string like: You can <a href="http://google.com">tap here</a> to search Google. Recognizing and embedding that link would be really helpful.

Ok, I see.
Currently, GONMarkupParser is intended only to generate NSAttributedString.
The best way to achieve this, is to create a new markup, handling .
Using this markup, so can update the string to add a hidden link (Using backspace UTF-8 character).
Then, you will have to subclass a UITextView to handle touches, and detect link.
I have developped a component doing this, for personnal use.
I will check if I can clean it to match this use case.

I would love this too!

OK, working on it.

Hi guys,
Just pushed a develop branch with a support for link markup.

If you want a callback when user click on link, display AttributedString in a UITextView, and implements following delegate method

#pragma mark - UITextViewDelegate methods
- (BOOL)textView:(UITextView *)textView shouldInteractWithTextAttachment:(NSTextAttachment *)textAttachment inRange:(NSRange)characterRange
{
    NSString *attachementValue = [[NSString alloc] initWithData:textAttachment.contents
                                                       encoding:NSUTF8StringEncoding];

    // Show link value
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Information"
                                                    message:attachementValue
                                                   delegate:nil
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil];
    [alert show];

    return NO;
}

UITextView should be selectable but not editable for this delegate method to be called.

To customize link attributes, you have to use linkTextAttributes property

Let me know if its ok for you.

Cool, I think you should support anchor tags in addition to link tags. So

<a href="http://www.hello.com">Hello World</a>

Should work.

[nicolasgoutaland]

Ok. I did rename it to "a href", to be more HTML like ;)
Let me know is everything is ok for you.

I've actually decided to go with another solution, I wrote my own small HTML-to-NSAttributedString parser on top of libxml. I think adopting anchor tags would still be a good thing for your library to support though.

Hi, done in last release ;)
