I am creating split view based application for iPad.
I have 1) a root view controller 2) a detail view controller
It is like menu and submenu.
Here I am planning to do. I would like to have navigation in root view controller.
It is recomonded to use or not. If it is recomended how is it possible.
There is a function in the Detail View Controller for showing or not showing the popover Button. Possibly you could adapt that in the App Delegate for the whole Detail View Controller? Just go through the source code provided by Apple. It is all well commented.
Not sure what you're asking. If you're asking whether it's recommended to do it like how you describe, then yes, that's the most recommended way to do it.
Root view controller (the smaller left side menu) usually contains the navigation stuff, while the detail view controller (the bigger right side view) contains all the detailed stuff.
You might want to take a look here for a How-To.

I'm trying to do a project for the iPad in which I'd like to utilized the split view controller. I'll be having different detail view controllers for each of the cells in the master view controller.
I saw one solution how to do this via storyboard segues in this site.
He basically linked each of his UITableViewCell to different detail view controllers. But I'd like to know if this is a "stable" or a "good" way of doing this. I mean, is it any better or as stable as doing it programmatically? What would be the consequences of doing his method, if there are any?
Here is the link to the solution I found
This is kind of a tricky one, even though it's an incredibly common use case.
1) One idea is to have an empty root view controller as your detail and it handles managing segues under the hood to quickly segue to the detail view you actually care about, utilizing the "replace" segue. This should "technically" fix having the "back" button at the top left and still allow you to pop to root and not have it show the empty controller. Haven't tested these though, so I'm not sure.
Edit: In Xcode 6, the "replace" segue is conveniently handled by a "show detail" segue which is used specifically for this type of view handling on Split View Controllers. I recommend using this method exclusively in new projects. See sample code.
2) The other idea is to have separate navigation controllers in your storyboard (one connected, the rest all stranded). One for each detail view type and tapping on the master menu will simply swap the navigation controller for the detail view to the one you care about.
Code similar to this in AppDelegate:
self.detailNavigationController = [self.masterNavigationController.storyboard instantiateViewControllerWithIdentifier:#"MyChosenNavigationControllerStoryboardId"];
self.splitViewController.viewControllers = #[self.splitViewController.viewControllers[0], self.detailNavigationController];
self.splitViewController.delegate = (id)self.detailNavigationController.topViewController;
The downside to this second way is that in memory tests, it doesn't appear that swapping a new nav controllers in frees up all of the memory that the old nav controller was using. So it's good to use for simple apps but not for anything crazy complex.
I need help with my control viewers in Xcode. In my storyboard, I created a navigation view controller. In which I created one view controller as my root view and added several objects in it.
Now in the general way, I'm trying to Ctrl + drag Element onto my View Controller. It doesn't show any Blue line like it is supposed to so.
Also I wish I can get some explanation or tutorials describing the method of creating views and controllers and linking them.
This is great tutorial to understand storyboards(single view for all the views in application) and Segues (transition between views). Go through both parts.
I am trying to develop an application that has screen flow similar to oracle app. I have attached the images here. Can anyone please tell how this can be achieved ?
Thanks in advance.
What you are looking for is a custom Split View Controller. The screenshots you provided are of custom split view controllers. The UIKit has UISplitViewController but this must be a fullscreen view controller.
To make a custom split view controller there's the old way, by having a main view controller and making your two master and detail controllers, adding their view to the main view controllers view.
You need to forward on calls from viewWillAppear:, viewWillDisappear: etc from the main view controller to the two controllers that you manage.
As of iOS 5, you can do something similar with view controller containment, this has a few more bells and whistles, more interesting it handles rotation animations better and all the call forwarding to the children controllers that you had to do manually in the first solution.
Check out this link for more details on custom split view controllers:

To answer your question directly: if you make a custom split view controller - yes you can add this as a detail view controller. But watch out, this isn't a UISplitViewController, so just be careful not to use that term so much.
Haven't really tested this, but doesn't this solve your problem?
Create a storyboard file
Drop in a SplitViewController
Delete the DetailViewController
Drop in another SplitViewController
Link the two together using CTRL-drag and select Detail
Set the size of the detail-splitviewcontroller to Detail
????
Profit!
Anyways, not sure if it really works, but give it a try. This is IOS5 though (I think, might try it out with IB).
It'll look something like this:
If you're going to have to write your own class, you might want to first look at https://github.com/mattgemmell/MGSplitViewController for inspiration.
I'm looking for a solution to create a sort of template in Objective C. I'll try to explain my problem.
I would create a sort of main view which has 1 side bar that remain always visible. This side bar have controls. The main view is responsible to load a Navigation Controller (UINavigationController seems to be ok) that manages other views. When switching a view to another, the sidebar always remain visible under the Navigation Controller and its views.
Through the controls of the sidebar, it's possible to send event to a specific view loaded by the Navigation Controller.
Any idea to create a similar template?
Thank you. Best regards.
It sounds like you want a splitview which is implemented by UISplitViewController.
I am working on an app to try and learn a bit more about the cocoa touch framework and am starting to use the UISplitViewController. From what I have learned so far, this has a property called viewControllers that is an array containing the master and detail view controllers for the app.
What I am trying to set up is a folder navigation system in the masterVC, then when a specific file is selected, it is opened in the detailVC. I have got the folder navigation working and can pass the details of the files between the two view controllers.
My problem is that there are several types of files that require different views to display them correctly.
For example a jpeg image will have an image viewer, whereas an html document will have a web view and a txt document will require a text editor view.
What is the best way to change the view controller of the detail pane?
Am I better to have a single View controller and swap different views in and out depending on the file type? Or is there a way to completely remove the viewcontroller and add the appropriate one in its place?
Thanks
I would think you should use multiple view controllers. There's bound to be a lot of logic in each of these individual view controllers you mentioned that should be properly contained within its own view controller.
As for displaying the appropriate view controller, you can easily add a view of a UIViewController to any UIViewControllers view, by doing: [self.view addSubview:myTextEditorVC.view]. So in other words, your detailVC could handle the logic of knowing which type of UIViewController it needs to display, instantiate that UIViewController, and display its view within the detailVC's view.
Hope this helps!
You should be swapping out different view controllers. In Xcode 6, you can use a "Show Detail" segue from the master to point to a different navigation controller that contains your different detail view.
Here's an quick example.
