Question

I’ve a NSDictionary that contain non omogeneus stuff. I need to understand what types of memebers there are into.

With the [dict description] I understand the values into, but not the type.
There is a way to do that?

Thanks

You can ask each object for it’s class (type) and then check if it’s the type you want, using NSObject’s -isKindOfClass: method. Note that if your object is, say, an NSMutableArray this would return true for [myMutableArray isKindOfClass:[NSArray class]]

Example:

id object = [myDict objectForKey:aKey];
if ([object isKindOfClass:[NSString class]])
    // It's an NSString!
