Parising iOS Simple XML

I'm a Java programmer and I'm facing iOS objective-c programming for first time.

I need to transform XML stream in objects: XML I send in Client/Server communication is a Object representation with values inside.

In Java platform I'm a fan of Simple XML libraries, they are small, fast and simple to use. After objects annotation the way to transform a well-formed XML to Object is really simple:

 Serializer ser = new Persister();
            ClassType classType = ser.read(ClassType.class, XML.toString());

Now classType instance contain values incoming with XML.

Is there a similar library can I can use on iOS programming? Can you suggest me the right library to transform XML in objects?

Thanks
