出棧操作----跨頁面pop，但是又不pop到rootViewController

for(UIViewController *controller in self.navigationController.viewControllers) {
            if([controller isKindOfClass:[OverWorkRecevice class]]){
                OverWorkRecevice*owr = (OverWorkRecevice *)controller;
                [self.navigationControllerpopToViewController:owr animated:YES];
            }
        }
