Finishing up a navigation transition in an unexpected state

我在做我的ios应用中，遇到了这样的情况：错误代码如下：

2013-05-13 21:46:47.985 xunYi4[31694:c07] nested pop animation can result in corrupted navigation bar
2013-05-13 21:46:48.336 xunYi4[31694:c07] Finishing up a navigation transition in an unexpected state. Navigation Bar subview tree might get corrupted.
2013-05-13 21:46:48.337 xunYi4[31694:c07] Unbalanced calls to begin/end appearance transitions for <personViewController: 0x75a01b0>.

使得我的运行的结果是，在调用pushViewConroller的时候出现了两次push，导致程序不能达到自己想要的效果，于是查找资料，最终我的解决方案是：如下：

personViewController *person = [[personViewController alloc] initWithNibName:@"personViewController" bundle:nil];
[self.navigationController popToRootViewControllerAnimated:NO];
person.navigationItem.title = button.titleLabel.text;
[self.navigationController pushViewController:person animated:YES];

达到了我要的效果，但是问题是这个报错的信息还是存在，请求高手给予指点
