NSAttributedString and Links on iOS

kdbdallas picture kdbdallas · Apr 24, 2011 · Viewed 16.2k times · Source

I am trying to add a hyperlink to certain parts of my text which is being handled and drawn using CoreText.

According to Apple's docs on CoreText I should be using addAttribute:NSLinkAttributeName however on iOS (4.3) it says it doesn't know NSLinkAttributeName. In my document searches it looks like NSLinkAttributeName only still exists on the Mac.

Is it available on iOS and I am just missing something? If it's not available how can I create a hyperlink on part of a text using NSMutableAttributedString and CoreText?

Thanks

As of iOS 7, UITextView supports links in attributed strings:

textView.attributedText = [[NSAttributedString alloc] initWithString:@"Stack Overflow" attributes:@{NSLinkAttributeName: @"http://stackoverflow.com"}];

By default, links are rendered as blue text. You can change the style with UITextView's linkTextAttributes property.

If you set editable to NO on the UITextView, links become tappable.
