  1. POHow to load a scene in a storyboard from a view controller
    text
    copied!<p>I am developing an application that loads a web page (using UIWebView) using Storyboard (I do know nothing about previous xib neither). I have already created a view controller for that UIWebView and everything works fine. The thing is: since previous versions of iOS don't allow to upload files, I need to make a new view (scene I thought it is called) that allows the user to pick and post a picture. I am able to develop both views separately and they work as expected but now I need to connect them based on event triggered when user wants to post a picture to the server. Using shouldStartLoadWithRequest I can catch that action, then I need to redirect to new view (which contains image picker and a button in order to upload the selected image) if iOS version is below 6.0 but I am really lost when it comes to load the new controller to show that view. Using buttons it is trivial but I don't know how to called inside the code. So far, I have a view controller linked to that scene and I have tried these ways:</p> <pre><code>WritePostViewController *postViewController = [[WritePostViewController alloc] init]; [self.navigationController pushViewController:postViewController animated:YES]; </code></pre> <p>And even calling the storybard: </p> <pre><code>UIStoryboard *sb = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil]; [sb instantiateInitialViewController]; UIViewController *vc = [sb instantiateViewControllerWithIdentifier:@"WritePostView"]; vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentViewController:vc animated:YES completion:NULL]; </code></pre> <p>The first approach does nothing and second one shows this error log:</p> <p><em>*</em> WebKit discarded an uncaught exception in the webView:decidePolicyForNavigationAction:request:frame:decisionListener: delegate: Storyboard () doesn't contain a view controller with identifier 'WritePostView'*</p> <p>I have been browsing and reading a lot but nothing solves my problem. For sure this a problem with my not-so-large knowledge about iOS but I am really stuck. I will thank any help.</p> <p>By the way, I need to come back after posting the file but I could imagine it is the same way opposite direction, right?</p>
