hidesBottomBarWhenPushed weird animation behaviour when push

Question:

I have a tab based application,Which contains no tab bar.

For hiding tab bar i am using hidesBottomBarWhenPushed method in storyboard.

but using this my view have strength animation like : <a href="https://drive.google.com/file/d/14H3Lym0bat4kaYP5rSlFqkJp8QF1xdZm/view" rel="nofollow">https://drive.google.com/file/d/14H3Lym0bat4kaYP5rSlFqkJp8QF1xdZm/view</a>

The tab bar is visible for some time and then it goes down.

For the solution i have put the following code :

<blockquote>

self.tabBarController.tabBar.hidden = YES;

</blockquote>

in Viewwillappear but did not work. also i have tried to hide it programatically before push but no luck

Here is my screen which is creating issue. I have removed all the code for hiding the tab bar, Now only hidesBottomBarWhenPushed set from storyboard. But still getting same issue.

I have hide the Bottom bar for checking is it related to layouts, but still my whole view goes up to down for the fraction of second.

Finally I have tried :

let chatRoom = ChatDetailViewController.viewController() chatRoom.hidesBottomBarWhenPushed = true self.navigationController?.pushViewController(chatRoom, animated: true)

But Same result.

Here is the screenshot of animation which is happening during push:

Answer1:

viewcontroller.hidesBottomBarWhenPushed = true

Use hidesBottomBarWhenPushed property as true when push viewcontroller.

<blockquote>

viewcontroller is object of UIViewController which are going to push into navigation stack.
