Read the documentation on -isKindOfClass: again. It does exactly
what you
want. -isMemberOfClass: performs the more specific test of excluding
subclasses.
In addition, a common gotcha (for me, anyway - it still gets me now
and again) is that you need to remember you're comparing "instances"
to "classes" with this method:
([value isKindOfClass:[NSString class]])
... not ...
([[value class] isKindOfClass:[NSString class]])
The former is correct, the latter is what I sometimes find myself
doing (and of course it fails).
Just for the record, you can also compare class, but not with the
isKindOfClass: method.
The method below is similar too ([value isKindOfClass:[NSString class]])
[[value class] isSubclassOfClass:[NSString class]]
