I know it's a stupid question, and I'm embarased to ask, but I've been
going through the docs for an hour and can't find it.
I'm loading some data from a database via web services, some of the
fields are nulls. The string is set to a CFNull in that case.
I'd like to filter on this somehow and return a blank string instead.
I have found an example on apple's site that using the [mystring
length] == 0 to test for this, but xcode does not like this.
I've searched through lots of docs without luck. There is probably a
simple way to do this, but damn if I can find it!
