How do I make UITextView's tappable links NOT have an underline? - objective-c

Question

I'm setting up a UITextView, and it has links that you can tap that will open in Safari.
UITextView *tv = [[UITextView alloc] initWithFrame:CGRectMake(35, 100, 300, 400)];
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithData:[#"<a href='http://google.ca'>test</a>" dataUsingEncoding:NSUTF8StringEncoding] options:#{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute: #(NSUTF8StringEncoding)} documentAttributes:nil error:nil];
tv.attributedText = attributedString;
[self.view addSubview:tv];
It basically takes an HTML string in (with an <a href=... in it) and then using the HTML parsing methods in iOS 7 gives me my tappable UITextView links.
However, if I add the following line before I add the text view to my view:
tv.linkTextAttributes = #{
NSUnderlineStyleAttributeName: #(NSUnderlineStyleNone)
};
Nothing changes. I can set it to be NSUnderlineStyleThick and it gets thicker. I can change the NSForegroundColorAttributeName to [UIColor redColor] to make the text red, but I cannot figure out how to get the text to not have an underline.
What am I doing wrong?

You can use [NSMutableAttributedString alloc] initWithString:str instead of NSAttributedString alloc] initWithData:data. Links will automatic detected and not underline
Try to use code below:
NSString *str = #"http://google.ca";
NSAttributedString * attributedString = [[NSMutableAttributedString alloc] initWithString:str];
tv.attributedText = attributedString;
