iOS 关闭当前页面再push到其他页面

偶遇需求，，，A页面兑换完后 经过 B等页面 -》进去C页面，C页面返回直接返回到A页面。【需要把中间B也页面关闭】
so :

-(void)jumpViewControllerAndCloseSelf:(UIViewController *)vc{

    NSArray *viewControlles = self.navigationController.viewControllers;
    NSMutableArray *newviewControlles = [NSMutableArray array];
    if ([viewControlles count] > 0) {

        for (int i=0; i < [viewControlles count]-1; i++) {

            [newviewControlles addObject:[viewControlles objectAtIndex:i]];

        }

    }

    [newviewControlles addObject:vc];
    [self.navigationController setViewControllers:newviewControlles animated:YES];

}
