Question

ios 为什么present时不能隐藏tabbar

Answer 1

//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。
