A method receives an object of type id. I want to make sure that the object is a string, so I'm using isKindOfClass. The problem is that sometimes the object is a NSConstantString and other times a NSCFString, so when the object passed is NSConstantString, isKindOfClass returns NO. Since both objects are strings, what test/ comparison would return YES?

Both of those should descend from NSString, so I'd try:

if ([aString isKindOfClass:[NSString class]]) {
    // Yep, it's a string
}
