Well, I suppose it's worth mentioning that read-only NSObject
variables are okay to use in this fashion because the compiler is
smart enough to retain the object when the block gets copied. (Beware
any retain cycles this may create! See Mike Ash's MAZeroingWeakRef.)
I was under the impression you were using the variable for general purposes.
I should have just stuck with Dave's recommendation to ask you to post
your code…
