The issue lies in how you’re trying to set up and use delegates with NSXMLParser. When using an external delegate, you need to make sure that it conforms to the NSXMLParserDelegate protocol, which has several methods like parserDidStartDocument, parserDidEndDocument, etc. You also need to implement these methods in your external delegate class. However, in your code, when you’re trying to set up the delegate for parseHTML2, you’re using @synthesize parseHTML2; in your header file, but then you’re not implementing any of the methods from the NSXMLParserDelegate protocol.
