NSOperationQueue leak?

I am trying to perform a method in a background thread using a NSOperationQueue like so:

NSOperationQueue *queue = [NSOperationQueue new];
    NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self
                                                                            selector:@selector(method)
                                                                              object:nil];

    [queue addOperation:operation];
    [queue release];
    [operation release];

The problem is that, analyzer says that there is a leak that is stored into queue.

How can I fix this?

Just wondering, what are you doing inside your method "method"? Are you using NSAutoreleasePool? By the way, use this answer to help you out.

Calling [MyClass new] is the same as calling [[MyClass alloc] init], it return object with retainCount = 1. So, it should be released after.

Are you releasing operation object? Try to add autorelease keyword

    NSInvocationOperation *operation = [[[NSInvocationOperation alloc] initWithTarget:self
                                                                                selector:@selector(method)
                                                                                  object:nil] autorelease];
