Here is the function where I get the compiler warning, I can't seem to figure out what is causing it. Any help is appreciated.

 -(void)displaySelector{
    //warning on the following line:
    InstanceSelectorViewController *controller = [[InstanceSelectorViewController alloc] initWithCreator:self];
    [self.navController pushViewController:controller animated:YES];
    [controller release];
}

Interface and implementation for the initWithCreator: method

-(InstanceSelectorViewController*)initWithCreator:(InstanceCreator*)creator;


-(InstanceSelectorViewController*)initWithCreator:(InstanceCreator*)crt{
    if (self = [self initWithNibName:@"InstanceSelectorViewController" bundle:nil]) {
        creator = crt;
    }
    return self;
}
