I would like to have a separate bar above the UISplitViewController on iPad. I will use this bar to show a logo.
I did some googling and reading but cannot find a solution to this other than create my completely own subclass to draw my screen like I want it. I'd like to avoid that if possible...
You should read about ViewController Containment to build your own Container Controller.

objc.io article:
http://www.objc.io/issue-1/containment-view-controller.html
Create your own container view controller. In its view this VC will add a navigation bar (or some other view that you can add your logo to) and the split view controllers view. It should also add the split VC as a child.
This is a custom subclass that you will create, but it is minimal code and requires no drawing code from you.

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.
It seems like this should be easy to figure out, but I haven't had any luck this afternoon. I threw together this quick, simplified storyboard mockup of my problem.
Basically, I would like the table view controllers below to also be in a tab bar controller (in addition to the already present navigation controller). The tabs would switch between the two table view controllers.
Right now, the view controller with the buttons acts as a sort of menu. Each button leads to one of the table view controllers. Ideally this view controller would not have the tab bar visible, and would only be reachable from back buttons on the nav bars of the table view controllers.
I've tried a few different ways of embedding into a tabbarcontrollers but none of them produce the desired result:
-I've tried selecting both table view controllers and embedding those in a tab view controller. The tabbar doesnt show up in simulator, and the 'unreachable scene' warning appears.
-I've tried embedding the initial nav controller into a tabbarcontroller. This creates a tab entry for the first 'menu' page. It also causes issues with push segues once I connect the tableviews to the tabview.
I would be fine implementing some programmatic options on top of the storyboard, I just chose storyboarding for this project since it's a relatively simple presentation of data.
What is the proper way of going about this? Thanks!
A tab bar controller needs to be the root view controller of your view hierarchy. It goes against the HIG and Apple's standards to put a tab bar controller inside of any other type of container controller.
From the Apple docs:
When deploying a tab bar interface, you must install this view as the
root of your window. Unlike other view controllers, a tab bar
interface should never be installed as a child of another view
controller.
So, the bottom line here is you need to rethink your design. One option would be to set the UITabBarController as the root view of your window, and then have each of your UITableViewControllers inside of a UINavigationController, which is placed inside of the UITabBarController. In this way, you still get the navigation bar, and stay within Apple's design guidelines (you also won't get those pesky warnings, and Apple may even be throwing an exception nowadays if you try to install a UITabBarController as anything other than the root view of the window).
I accept JMStone answer but we might get into situation where we need to put tab bar controller inside other controller especially table view controller.
Please refer Storyboard navigation controller and tab bar controller
and also the good example by Matthjin: http://cl.ly/VQLa
Hopes it help some one who want to put tab bar controller inside table view controller and wants proper navigation.
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:
http://www.mindtreatstudios.com/how-its-made/custom-uisplitviewcontroller-ios/
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 was looking to implement something like the image below, and really have no idea how it's done and was wondering if someone had a quick design idea (no code is necessary or anything). Is it a footer view for the table view? is it some unknown footer view for a popover controller? Is it some way to integrate a toolbar from the UINavigationController 'into' the popover? I guess I could always create a custom view and display it 'like' a popover. Thanks for any help.
UIPopoverController will actually do a lot of that for you. If you set its content view controller to a UINavigationController, the contents of that navigation controller’s current view controller’s navigation item will display embedded in the top of the popover. I believe setting the view controller’s (not the navigation controller’s) toolbarItems will have the same effect at the bottom.
In this case, it looks like they wrote a custom popover controller; it doesn’t have an arrow attached, and the top of it is shaded a little differently from the standard UIPopoverController. But I’m pretty sure you can use the methods I just described to achieve a similar effect without having to roll your own popover.
I'm running into a problem with an iPad app where I would like to have UINavigationControllers in both of the views within a UISplitView. I've looked through other similar questions here, but most link to a tutorial online that doesn't completely solve the problem. Here's a 2-minute walkthrough to re-create the problem I'm having:
Create a New Project in XCode, starting from the Split View-based Application template.
Add the following NSLog statement as the first line within the DetailViewController's willHideViewController method:
NSLog(#"toolbar: %#", toolbar);
If you run the application now, the log will show that the DetailViewController's toolbar is alive and well. Now...
Open MainWindow.xib and expand the SplitViewController.
Drag a Navigation Controller from the library on top of the DetailViewController.
Expand the new Navigation Controller and change the class of the UIViewController within to a DetailViewController.
Ctrl-drag from the SplitViewController to the DetailViewController and assign it as the delegate.
Save MainWindow.xib and run the app again.
At this point, the detail view has a navigation bar and an empty toolbar. If you view the logs, you should find that the toolbar is null. Why is this? Am I missing some sort of connection in Interface Builder? Is the navigation bar the problem for some reason?
Unlike the tutorial at http://www.cimgf.com/2010/05/24/fixing-the-uisplitviewcontroller-template/, I would like to keep both the navigation bar and the toolbar (preferably with the toolbar at the top when in portrait and not visible when in landscape), so that I still have a functional "Back" button when the iPad is in portrait orientation.
Does anyone have any suggestions for fixing this problem? An example project with this sort of set-up would be ideal.
You can certainly use a navigation controller on the detail view of a split view controller. In fact, the iPad Settings app uses this approach. Probably the best way to get this setup is to create a new project in Xcode 4.x and select the "Master-Detail Application" template. It will generate a split view controller with 2 navigation controllers, one for the left view and one for the right view.
To your toolbar question, to keep things simple I would put a toolbar in the bottom. You can still put bar button items on the top navigation bar, although you can only put them in the left, middle, or right. If you need lots of items on the top bar, one way is to add a toolbar to the detail view and hide the navigation bar in the viewWillAppear event of the detail view class.
Here is an example on how to hide the navigation bar and show the toolbar:
- (void) viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
self.navigationController.toolbarHidden = NO;
self.navigationController.navigationBarHidden = YES;
}
I've found the built-in UISplitViewController to behave badly when trying to combine it with most of the other built-in view controller subclasses. Matt Gemmell's MGSplitViewController is a lot more flexible and has worked pretty well for me, despite the odd glitches (though those are at least fixable as the source code is provided).
