//1.设置self.tabBarController.tabBar.hidden=YES; self.tabBarController.tabBar.hidden=YES;//2.如果在push跳转时需要隐藏tabBar，设置self.hidesBottomBarWhenPushed=YES; self.hidesBottomBarWhenPushed=YES; NextViewController *next=[[NextViewController alloc]init]; [self.navigationController pushViewController:next animated:YES]; self.hidesBottomBarWhenPushed=NO;//并在push后设置self.hidesBottomBarWhenPushed=NO;//这样back回来的时候，tabBar会恢复正常显示。原文：http://www.cnblogs.com/z-j-w/p/4747496.html
