Hello...
There is a single unique instance of CFNull, so you can use pointer equality...
http://developer.apple.com/documentation/CoreFoundation/Reference/CFNullRef/index.html
if (someString == kCFNull) {return @"";}
else {return someString;}
Hope that helps,
Louis
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.
