不同的setHidesBottomBarWhenPush在子视图和父视图控制器上

Question

1. 显示父vc上的底栏，当我将子vc添加到父vc时。
当我从父vc中删除子vc时，
2. 然后隐藏父vc上的底栏。

怎么做？

这是我当前的代码，没有setHidesBottomBarWhenPushed

ParentVC：didload

[self addChildViewController:childVC];
[self.view addSubview:childVC.view];
[childVC didMoveToParentViewController:self];

针对子vc的行动

[self willMoveToParentViewController:nil];
[self.view removeFromSuperview];
[self removeFromParentViewController];

Answer 1

试试这个

  UIViewController *yourViewController  = [self.storyboard instantiateViewControllerWithIdentifier:@"VCIdentifier"];

如果您需要导航栏

UINavigationController *navController = [[UINavigationController alloc]initWithRootViewController:objAddRatingVC];
 [navController setModalPresentationStyle:UIModalPresentationCurrentContext];
 [self.navigationController presentViewController:navController animated:YES completion:nil];

如果您不想要导航栏

[yourViewController setModalPresentationStyle:UIModalPresentationCurrentContext];
 [self.navigationController presentViewController:yourViewController animated:YES completion:nil];
