hidesBottomBarWhenPushed推送时出现奇怪的动画行为 [英] hidesBottomBarWhenPushed weird animation behaviour when push

问题描述

我有一个基于标签的应用程序，其中没有标签栏.

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

要隐藏标签栏，我正在情节提要中使用hidesBottomBarWhenPushed方法.

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

但是使用此视图，我的力量动画如下所示: https://drive.google.com/file/d/14H3Lym0bat4kaYP5rSlFqkJp8QF1xd >

but using this my view have strength animation like : https://drive.google.com/file/d/14H3Lym0bat4kaYP5rSlFqkJp8QF1xdZm/view

标签栏显示一段时间后会下降.

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

对于解决方案，我输入了以下代码:

For the solution i have put the following code :

self.tabBarController.tabBar.hidden =是;

self.tabBarController.tabBar.hidden = YES;

Viewp中的

会出现，但不起作用. 我也试图在推送之前以编程方式将其隐藏，但没有运气

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

这是我的屏幕，正在产生问题. 我已经删除了用于隐藏选项卡栏的所有代码，现在仅从情节提要板中隐藏了hideBottomBarWhenPushed集. 但仍然遇到同样的问题.

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.

我已经隐藏了底部栏，以检查是否与布局相关，但我的整个视图仍会上下移动几分之一秒.

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.

最后我尝试了:

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

但结果相同.

以下是在推送过程中发生的动画的屏幕截图:

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

推荐答案

viewcontroller.hidesBottomBarWhenPushed = true

在按下viewcontroller时，将hidesBottomBarWhenPushed属性用作true.

Use hidesBottomBarWhenPushed property as true when push viewcontroller.

viewcontroller是UIViewController的对象，该对象将被推入导航堆栈.

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