I have a TabManViewController (that you can find in this repository https://github.com/uias/Tabman ) which embeds 3 Viewcontrollers.
In one of this embedded ViewControllers I have one UIView that is draggable with a UIPanGestureRecogniser.
When I drag it I see that it goes behind the TabMan Bar, while I want it to go over it.
I tried this snippet of code in the viewController that embeds the view but It doesn't work.
self.view.bringSubviewToFront(cardView)
How can I bring the view above everything else?
You need to add it to either
1- The tabBarController' view
2- Window's view
You have to replace "view" in below code with the parent view of cardview
self.view.bringSubviewToFront(cardView)
self.yourCardview'sParentView.bringSubviewToFront(cardView)

I am working on a project which contains 3 container view with 3 child viewcontrollers. I am new at container view So I want to know where to write code of that child view controllers. I load that viewcontrollers with adding child viewcontrollers in containerview with use of seague.
As per I googled, There are demos like they only load viewcontrollers in containerview with just changing background color.
I want to know that If I have to make different classes for that view controllers that embed in containerviews?
Thank you for your help
Yes you have to create UIViewController class for each embedded View Controller.
Doing this will give you control over the embedded View Controllers like normal View Controller do.
I have 2 ViewControllers.
VC1 has a 2 views inside it.
I want to get MenuUIVC to appear in one of my views belonging(child) to VC1.
I tried this code inside of VC1 but it didn't work.
MenuUIVC * menuViewVC = [[MenuUIVC alloc] init];
menuUIView = menuViewVC.view;
I expected to be able to see the MenuUIVC inside the view (menuUIView) which is a child of VC1. I have the IBOutlets all hooked up on the storyboard.
You can use Container views to get View Controller inside a View Controller. And, you can get the reference to it through prepareForSegue() method.
Links for description:
iOS Container View
The Easy Way to Switch Container Views in iOS
If you are using UIView, then why don't you use
[menuUIView addSubview:menuViewVC.view];
Another option is to use childviewcontrollers.
See these links for example:-
adding view controller as child view in ios
Add child view controller to current view controller
Using container or child view controller, gives you full fledge option of using View Controller properties, which you will not get in UIView.
Say for example, you can you orientation delegate methods, which you can't using in UIView class directly.
Hope this can help you.

you can go for container view if you want to do it using IBOutlets & storyborad.
but if you want to do it using code then follow the below steps :
initialise & create parent view controller.
then add required child view as a subview with negative frame.
now change the frame with UIView animation whenever required. & do add tap gesture recogniser on part of screen other than the child view to remove it back to the initial position.
I am having a hard time understanding why you can put UIViews outside the UIViewController on the storyboard, and what the use case of it might be.
For instance, on the storyboard I can add UIToolbar, UIAcitivtyIndicator and UIProgressView that is outside of the UIViewController. Is this mean there is a way for you to reference those Views that are outside UIViewController and potentially display them somehow either programmatically or embed those like you would do with a ContainerView?
Yes, it absolutely is possible to do what you're describing!
When you add objects that are outside the view controller, they appear in what Apple calls the "Scene Dock". Apple has the following suggested usage for the scene dock:
If a view is not part of the main view hierarchy — such as a pop-up
menu — add the view to the scene dock. In a running app, the system adds
and removes these kind of views from the view hierarchy when they are
opened and closed.
The steps to make this work are below:
Open the storyboard.
Open the utilities area for the workspace window by clicking the
utilities button in the
toolbar.
In the utilities area, select the Object library by clicking the Object Library button in the library bar.
On the storyboard, select the scene to which you will add the extra view.
Drag a view class object from the object library into the the scene dock.
And importantly...
The added view is a part of the view controller. It will be
instantiated along with the rest of the views. You can attach the view
to a property of the view controller that has an IBOutlet. You can add
more than one view to the scene dock.
(These steps were originally copied from here - unfortunately this page seems to have been deleted by Apple at some point).
I would like to make similar effect that Facebook app has. So I would like to create navigation slide-out effect.
But when I place UIViewController with menu beneath parent UIViewController with content and then I move parent view aside my menu doesnt show up. Everything I can see is black screen. But menu frame is in the right position.
Any sugestion what should I do?
Content view will be separate UIViewControllers.
I was in the same situation than you and finally I used a custom class which is inspired on FaceBook and Wunderlist apps and is really simple to add into the project:
https://github.com/John-Lluch/SWRevealViewController
The child view controller is always above parent view controller's view.
I think the old and the new view controllers should be siblings and use a parent view controller to add them both.
In fact, the child controllers of native UINavigationController are siblings rather than child-parent relationship.
I would urge you not to do this on your own but to use one of the many libraries out there that have been heavily tested by many contributors. One of the good ones is MMDrawerController but there are many others. Take a look at cococontrols for many more examples.
I've previously implemented a similar mechanic to this using custom transitions, which were introduced in iOS7. For example: could present the menu modally, but using a custom transition have it appear from the left and only take up a proportion of the screen.
Using custom interactive transitions will also allow you to use a pan gesture recogniser to drag your main view controller back on top of your menu - like in the Facebook app.
Here's a good tutorial on Custom Transitions: http://www.thinkandbuild.it/ios7-custom-transitions/
I think I am having a case of disappearing up my own arse.
I am creating a small view on a ipad thats for settings (so not full scree), within this view. I need a navigation controller to show another view.
At the moment I have one class / xib
The xib contains the main view (graphic / boarder). This view is linked to the files owner and appear.
On the same xib, I also have a navigation controller that contains the inner view.
OnViewDidLoad I add the navigationcontroller.view to the subview and it appears. However I cant push anything off it. I wired up the delegate and etc but I am sure I am missing something stupid
Can I do this all within one controller / xib?
The only code I have done is
[self.view addSubview:mainNavigationController.view];
Is there some code I need to do for the navigationController
Just adding the navigation controller as a subview doesn't hook up the navigation controller to the view controller hierarchy properly. That's probably why it doesn't work.
Also the properties that need to be set are readonly properties, so I don't think there's anything you can really do about it.
