假设出现：
nested push animation can result in corrupted navigation bar
Finishing up a navigation transition in an unexpected state. Navigation Bar subview tree might get corrupted.
一般这样的情况是在自己定义的tabbarController 的ViewWillAppera中没有调用superWillAppera， 调用父类方法就OK。
[super viewWillAppear:animated];
在用TabbarController中出现navigationController 嵌套报错
