弹出动画在UITabbarController的第一个UINavigationController中不起作用 [英] Pop animation is not working in first UINavigationController of UITabbarController

问题描述

我不知道我的代码有什么问题.我已经成功开发了应用程序，并且一切正常，除了我第一次启动应用程序时，在侧面优先导航控制器中，弹出动画无法正常工作.似乎是Pop without animation.当我更改选项卡并返回第一个选项卡时，它的工作正常.并执行push-pop，然后工作正常.

I don't know what is wrong with my code. i have developed app successfully and all the things working fine except when i launch app first time, In side first navigation controller, the pop animation is not working fine. it seems that Pop without animation. and its working fine when i changed the tab and come back on first tab. and doing push-pop then its working fine.

自从一周以来，我一直试图找出问题所在.但是由于冗长的代码而无法获得成功.我尝试了与创建Tabbar Demo相同的动画，并且效果良好.

I tried to figure out problem since week. but could't get success because of lengthy code. I have tried the same animation with creating Tabbar Demo and its working fine.

我的应用具有以下层次结构.

My app has following hierarchy.

UINavigationController --> UIViewController --> UITabbarController --> Four UINavigationController --> UIViewControlle.

我在storyboard中服用了UITabbarController.

推荐答案

我知道我问了这个问题，并且也提供了解决方案.我很久以前就问过这个问题，但由于存在不合逻辑的错误，我没有得到任何解决方案.并非每个Tabbar基本应用程序都具有相同的功能.我在这里添加了经过长时间调试的解决方案，发现即使单行也可能破坏您的项目.

I know that i asked the question and also provide solution for same. I have asked this question long time ago and i am not getting any solution for this because there is illogical bugs. Not every Tabbar base application have same. Here i am adding solution that is result of long time debugging and i found that even single line can break your project.

实际上，我已经从情节提要中添加了UITabbarController，并以编程方式创建了UITabbarController类，并在storyboard内使用UITabbarController进行了类型转换.

Actually i have added UITabbarController from storyboard and programmatically created UITabbarController class and type cast it with UITabbarController inside storyboard.

这是我的问题，我忘了在-(void)viewDidAppear:(BOOL)animated方法中编写[super viewDidAppear:animated];.所以我会第一次打破流行动画，然后它将正常工作.

Here my problem is, i forgot to write [super viewDidAppear:animated]; inside -(void)viewDidAppear:(BOOL)animated method. so i will break pop animation first time then it will work fine.

获得此解决方案后，即使我也不知道此行如何影响整个代码.但我不希望其他人浪费时间来发现这样的单行(意外问题)问题.所以我在这里添加此代码.

After getting this solution, even i don't know how this line affect whole code. but i don't want the other people to waste their time to find out such single line (unexpected issue) problem. so here i am adding this code.

-(void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:animated];
}
