你应该使用类似的东西：

    NSMutableArray *allViewControllers = [NSMutableArray arrayWithArray: self.navigationController.viewControllers];
    for (id object in allViewControllers) {
        if ([object isKindOfClass:[FacebookClassNameToremove class]]) {
            [allViewControllers removeObject:object];
        }
    }
    self.navigationController.viewControllers = allViewControllers;
