TabbarController跳转

[BigPoro]

根视图初始化：
tabController.viewControllers = @[[[RTRootNavigationController alloc] initWithRootViewController:[story instantiateViewControllerWithIdentifier:@"Root"]],
[[RTRootNavigationController alloc] initWithRootViewController:[story instantiateViewControllerWithIdentifier:@"Remove"]],
[[RTRootNavigationController alloc] initWithRootViewController:[story instantiateViewControllerWithIdentifier:@"Scroll"]],
[[RTRootNavigationController alloc] initWithRootViewController:[story instantiateViewControllerWithIdentifier:@"Table"]]];
self.window.rootViewController = tabController;

在某个二级控制器内。跳转第二层TabbarController：
UITabBarController *tabController = [[RTTabBarController alloc] init];

tabController.viewControllers = @[[[RTRootNavigationController alloc] initWithRootViewController:[story instantiateViewControllerWithIdentifier:@"Root"]],
                                  [[RTRootNavigationController alloc] initWithRootViewController:[story instantiateViewControllerWithIdentifier:@"Remove"]],
                                  [[RTRootNavigationController alloc] initWithRootViewController:[story instantiateViewControllerWithIdentifier:@"Scroll"]],
                                  [[RTRootNavigationController alloc] initWithRootViewController:[story instantiateViewControllerWithIdentifier:@"Table"]]];
[self.rt_navigationController pushViewController:tabController animated:YES complete:^(BOOL finished) {
    [tabController.navigationController setNavigationBarHidden:YES animated:YES];
}];

然后再第二层的TabbarController的某个二级控制器手势返回，会直接回到第一个TabbarController，而不是第二个TabbarController的一级控制器。

遇到同样的问题，请问有什么解决方案吗？
