隐藏TabBar的两种方式

LogNewVController *loginVc = [[LogNewVController alloc]init];
loginVc.hidesBottomBarWhenPushed:YES;
[self.navigationController pushViewController:loginVc animated:YES];

比这样隐藏

LogNewVController *loginVc = [[LogNewVController  alloc]init];
self.hidenBottomBarWhenPushed = YES;
[self.navigationController pushViewController:loginVc animated:YES];
self.hidenBottomBarWhenPushed = NO;

更好，毕竟少写一行，哈哈哈☆
