I have an NSArray and need to filter out any strings that are null or rather, have ‘ ‘ (empty string). How do I do that? I have tried doing:
NSPredicate *predicateName = [NSPredicate predicateWithFormat:@"(name!=nil)"];
but that doesn’t seem to work. Or maybe it does but there are different kinds of null…
If you don’t use Core Data, you could do:
If the string is empty, this will fail (because
0 == 0). Similarly, ifnameisnil, it will also fail, because[nil length] == 0.
