This method is automatically called, since I am invoking
setValuesForKeysWithDictionary: in init method.

Actually I am indirectly trying to identify class of property, through
key parameter, the NSLog statement added within - setValue: forKey: is
wrong, I was trying to do something like this:
- (void)setValue:(id)value forKey:(NSString *)key
{
NSLog(@"key class: ",[[self valueForKey:key] class]); // it is
printing nil, prints correct value if key is initialized in init
method
}
