NSXMLParser 's delegate and memory leak

I am using a NSXMLParser class in my program and I assign a delegate to it. This delegate, though, gets retained by the setDelegate: method resulting to a minor, yet annoying :-), memory leak.

I cannot release the delegate class after the setDelegate: because the program will crash.

Here is my code:

self.parserDelegate = [[ParserDelegate alloc] init]; //retainCount:1
self.xmlParser = [[NSXMLParser alloc] initWithData:self.xmlData];
[self.xmlParser setDelegate:self.parserDelegate]; //retainCount:2
[self.xmlParser parse];
[self.xmlParser release];

ParserDelegate is the delegate class.

Of course if I set 'self' as the delegate, I will have no problem but I would like to know if there is a way to u开发者_JAVA百科se a different class as delegate with no leaks.

Thank you in advance.

From the documentation on setDelegate:

"An object that is the new delegate. It is not retained. The delegate must conform to the NSXMLParserDelegate Protocol protocol."

So no worries. Additionally, even if it was retained, a proper NSXMLParser class would release the delegate in 'dealloc'. So I don't think you have a leak.

The reason you're crashing, is you are deallocating the delegate, since you bring the retain count down to 0.

If you have the property parserDelegate set as retain and using the synthesized methods (by using self) to set it initially, then that is probably your leak.
