Unable to set NSXMLParser delegate to self

Question

I'm trying to create an NSXMLParser and call its delegate methods. On setting the delegate to self (2nd line below) I get a warning Sending 'XMLParserViewController *' to a parameter of incompatible type 'id <NSXMLParserDelegate>'. What am I missing here?

NSXMLParser *parser = [[NSXMLParser alloc]initWithData:data];
[parser setDelegate:self];
[parser parse];
[parser release];

Answer 1

Change the line: @interface XMLParserViewController : UIViewController (in your .h file) to:

@interface XMLParserViewController : UIViewController <NSXMLParserDelegate>

You forgot to set your UIViewController as a delegate of the delegate (if you will).

Answer 2

In the declaration of self you should have:

@interface YourClass <NSXMLParserDelegate>

to let the compiler know that your class conforms to the NSXMLParserDelegate protocol.
