Check if object is Class type

Question

I have a method that receives a NSArray of Class objects and I need to check if they all are Class type generated with the code bellow

Answer 1

If you need to verify if the object in the array is a Class object then you can verify if it responds to class methods.

for ( id obj in arr ) {
    if (([obj respondsToSelector:@selector(isSubclassOfClass:)])
          && (obj == [NSObject class]) ) {
        NSLog(@"%@", obj);
    }
}

Once you know it is a Class object by verifying if it responds to isSubclassOfClass: then you can check for direct equality with [NSObject class].
