No, that's not right. The attributes need to be set in the attributed 
string. The document attributes are something else entirely (more 
specifically, they contain information about the *document*, not text 
attributes which is what NSLinkAttributeName is). You probably want to 
do -initWithString:attributes: rather than just -initWithString:, then 
pass nil for the documentAttributes: argument.

Also, consider using -dictionaryWithObjectsAndKeys: or -
dictionaryWithObject:forKey: rather than -
dictionaryWithObjects:forKeys:.  They're more efficient and involve 
less typing too :-)

Kind regards,

Alastair.
