工具栏后退按钮不起作用 [英] ToolBar back button is not working

问题描述

我使用故事板执行一个项目，在一个viewcontroller中，我有一个按钮.当我单击该按钮时，它将移至下一个viewcontroller，但它是单独的xib文件.现在，我尝试向该xib文件添加一个后退按钮，这样我就可以移回我的情节提要，但它对我而言不起作用?

我尝试了以下代码，以便从xib转到情节提要viewcontroller

viewcontrollerOne *list= [self.storyboard instantiateViewControllerWithIdentifier:@"detail"];
[self presentModalViewController:list animated:YES];

请让我知道其不起作用的原因吗?

解决方案

当您要将故事板中的xib移到视图控制器时，此代码将起作用，

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"IDENTIFIER"];
[self.navigationController pushViewController:vc animated:YES];

Iam doing one project using storyboard ,in one viewcontroller i have a button.When i clicked that it will move to next viewcontroller but its a separate xib file. Now i tried to add aback button to that xib file So i can move back to my storyboard but its not working form me ?

I tried following code for moving from xib to storyboard viewcontroller

viewcontrollerOne *list= [self.storyboard instantiateViewControllerWithIdentifier:@"detail"];
[self presentModalViewController:list animated:YES];

please let me know the reason why its not working?

解决方案

This code will work when you want to move from an xib to a viewcontroller in Storyboard,Its working for me.

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"IDENTIFIER"];
[self.navigationController pushViewController:vc animated:YES];
