返回多层
返回指定的某个vc用下面（通过index定位）
[self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:2] animated:YES];
[self.navigationController popToViewController: [self.navigationController.viewControllers objectAtIndex:self.navigationController.viewControllers.count-2] animated:YES];
或（通过class定位）
for (UIViewController *controller in self.navigationController.viewControllers) {
if ([controller isKindOfClass:[你要跳转到的Controller class]]) { [self.navigationController popToViewController:controller animated:YES]; }
}
