I noticed that setText is able to take attributed strings. Using setText seems to resolve the problem of old links not being removed but introduces a different problem - it detects phone numbers in my attributed string despite not doing anything to enable this, is it possible to disable the checking? NSTextCheckingType doesn't seem to have a none option for enabledTextCheckingTypes.
It seems that i'm the one setting the link attribute on the attributed string, everything seems to be working as expected with setText.

Also see this note in TTTAttributedLabel.h on the attributedText property:

@warning Do not set this property directly. Instead, set @c text to an @c NSAttributedString.

As you've noted, you should instead call setText: with either a regular or attributed string.

I was already using attributed strings when i decided to drop in TTTAttributedLabel so I didn't see any warnings. I don't know how often setAttributedText is used but maybe it would be useful to add a deprecated warning on it.
Anyways thanks for the reply and your work on this repo, it saved me a lot of time when i had to make my labels work with links.

I just had the same issue, so yeah, a warning would be nice
