How to check if a UIViewController is of a particular sub-class in objective c?

Question

I want to be able to check the type of a UIViewController to see if it is of a certain type like this

c code

if (typeof(instance1) == customUIViewController) 
{
  customUIViewController test = (customViewController)instance1;

  // do more stuff
}

Answer 1

The isKindOfClass: method indicates whether an object is an instance of given class or an instance of a subclass of that class.

if ([instance1 isKindOfClass:[CustomUIViewController class]]) {
    // code
}

If you want to check whether an object is an instance of a given class (but not an instance of a subclass of that class), use isMemberOfClass: instead.
