// 以前在每个页面的 didload ... viewwillapper viewwilldisapper 写了无数这句话，各个页面乱七八糟
self.navigationController.navigationBar.hidden = xx；
// 右划返回出现前还没啥问题,自从出了右划返回简直坑不要太狠～(黑边)
// 以为很简单的bug结果搞了半天。。。。
解决方案
// BaseViewController中
/**
* nav的代理指向自己,实现代理方法
* [self.navigationController setNavigationBarHidden: animated: animated];
替代self.navigationController.navigationBar.hidden = xx；
