I am writing an application for mac OSX in swift and I would like to separate the code clearly so I am looking for a way to have a view controller for each NSTabViewItem in a NSTabView without use the Tab View Controller. Is it possible ?
Finally, I found a solution.
It’s possible to do that with a “Container view”. I put a Container View in a view. I created a new view controller. Finally, I linked both with Ctrl-Drag from container view to the new view controller and selected "embed".

I have a storyboard setup with the main view having a bunch of buttons and a container view and I would like for a different view to be loaded into that container view each time I press one of those buttons, kind of like a tab view controller works but without using one of those.
Also, later on I plan to have buttons inside those views that load other views replacing the views themselves.
Anyone can give me some hints?
Thanks
"Container View defines a region within a view controller's view subgraph that can include a child view controller. Create an embed segue from the container view to the child view controller in the storyboard."
You mentioned NSContainerView, so I assume you're trying to do this on macOS, not iOS. Here's a useful article and code project (for iOS 6, but I was able to set up switchable subviews in iOS 9 using this as a guide):
http://sandmoose.com/post/35714028270/storyboards-with-custom-container-view-controllers
The important bits are using the embed segue, then wiring the view controllers together through a combination of viewDidLoad and prepareForSegue, and then finally loading one of the switchable view controllers (say one for each of your buttons) from the storyboard, where they are not connected to anything else.
Currently have I implemented iAd and AdMob to each and every view controller in my Xcode project. I have about 6 view controllers and every time I switch back and forth between them one adbanner disappear and another appears. I want to make only one single adbanner for all view controllers. So even though its a transition between two view controllers, only one adbanner will be visible and it will not disappear and appear again.
But I also need to reach it from each class. So I can show it and hide it when I want to.
I would appreciate a ditailed step-by-step instruction.
INFO:
I am using storyboard. I am developing for iOS 6.0 and higher. I am using navigation controller.
So pass the banner view from one view controller to the next just as you'd pass any data. Install the view in the view hierarchy in each controller's -viewWillAppear method. You can pass the view between controllers in your -prepareForSegue method. If you're not sure how to pass objects between view controllers, search here -- here are many questions covering exactly that topic.
I am writing an iOS / CocoaTouch app and I am facing the following problem :
I have a detail view (think of an overview of one given object)
This detail view can present other elements
Any of these other elements can be viewed in this exact same detail view (I mean, another instance of this view / view controller using the viewed object model.
The only problem I have is that I am not able to create a segue from a view to the same view in the storyboard editor. Therefore, I cannot create the segue at all, cannot assign an identifier, and thus cannot trigger it from code.
Is there any way to implement this ?
This is as simple as a detail view pushing another, each of them having one dedicated instance of the view controller with their respective object model.
Thank you so much, I looked everywhere and cannot find any topic related to this.
Christophe.
Segues are between view controllers, not views (even though a view can act as a trigger). If you want to have a segue to a new view controller, create a new instance of it in the storyboard, assign its identity to the same class as your original detail, and define the segue.
If you're only trying to change which view is displayed inside a single view controller, then selectively setting views hidden and not-hidden can work...or adding/removing sub-views.
I followed the "Storyboard tutorial" and made some Table View Controllers; now I want to change one of them to a regular View Controller.
Is there a way to do that without making a new one?
One option is to edit the storyboard file directly. Navigate to the Storyboard in Finder and open with any text editor. Find the view controller in question and change the node in the xml from tableViewController to viewController.
This saves the pain of having to recreate the view controller, which comes in handy when you have a lot of connections made. This also works the other way around. If you have a viewController that started out as a plain view controller but you want to turn it into a table view controller you can simply edit the file reversing the node.
You need to create a new view controller and drag a tableview into it. Remember to set the delegate and datasource of the tableview to the view controller.
I have had the same scenario where I needed to change the Tableviewcontroller to a view controller. I googled for a work around but ended up without an exact solution. What I did was added a subclass of view controller and dropped a UITableview and added some more controls that I wanted. Pretty inconvenient but worked the way eventually!
In iOS5 using storyboard feature I want to create a custom container which will have 2 ViewControllers embedded in it. For Example, embed Table view controller as well as a view controller both in one ViewController.
That is, one view controller will have 2 relationship:
to table view controller
to view controller which in turn will have 4 UIImage view Or UIButton in it
Is creating this type of relationship possible using storyboard's drag drop feature only & not programmatically?
,You should only have one view controller to control the scene. However, this viewController might have two other view controllers that control particular subviews on your scene. To do this you create properties in your scene viewController, in your case one for your tableViewController and one for your view. I like to keep things together so I make both these viewControllers outlets and create them in interface builder. To create them in interface builder pull in an Object from the Object library and set its type to the relevant viewController. Hook it up to the appropriate outlet you just created in your scene's viewController - Note: this is important otherwise the viewController will be released if you are using ARC and crash your app. Then hook these viewControllers up to the view you want them to control and you are done.
Alternatively you can instantiate and hop up your viewControllers in your scenes viewController should you prefer to do this.
Hope this helps.
Edit: On reflection this is not a good idea and actually goes against the HIG you should maintain only one ViewController for each screen of content and instead try to create a suitable view class and have the single view controller deal with the interactions between the various views.
There is a way to do it that isn't too hacky. It is described at the following URL for UITabBarControllers, which you could use the first view controller in the list control the first subview, and the second one control the other. Or, you can probably adapt the code to work with UISplitViewController.

Basically, it works by replacing the tabbarcontroller at runtime after iOS has finished configuring it.
