Hi,
I am taking a shot at creating a Twitter App. I was wondering if its possible
to Subclass UItextview to detect hashes and respond to them. For example:
This is a tweet #iamtrending
I've seen this done in other Apps, but not sure where to start.
Thanks for the help.

Thanks Fritz.
This is a great suggestion.

I am having trouble setting the size of the call out bubble on my

This line has no effect:

Here is my code:

Yes
If you have declared the property to be read-only, then the retain keyword is
