I wonder if it is possible to create a UITabBarController without declaring, one uiNavigationController?
because in some examples that I find on the internet, all make use of navigationcontroller and then report a tab bar, as I am a beginner, I would like you answer me the question above
Yes; any viewcontroller can be embedded within a tabBarController. Ray Wenderlich has a good tutorial here:
http://www.raywenderlich.com/50308/storyboards-tutorial-in-ios-7-part-1
You don't need a nav controller for use tab controller. Just create a tab bar controller, setup him, and insert controllers you want.

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.
Helpful links:
iOS Reference: https://developer.apple.com/library/ios/documentation/uikit/reference/UIViewController_Class/Reference/Reference.html
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 want to use a UISearchBar that doesn't move, like in Apple's Contacts app. I also want to these components at the same depth, and I don't want the search bar in the tableview header.
UINavigationBar
UISearchBar
UITableView
When I try to attach UISearchBar below UINavigationBar in storyboard, interface builder doesn't show me suitable guideline. The guideline only generates when in tableview.
Is there no way to attach the search bar below UINavigationBar without programming?
I'm also searching an elegant way to build the search bar..
What I have now is a UINavigationController, inside which I have a UIViewController.
This UIViewController contains UISearchBar and UITableView. You can program the search bar on top and tableView below it.
vborra's link also helps.
It is easy to do what you are looking for, UISearchBar is somewhat meant for this. See the tutorial Here: http://www.appcoda.com/search-bar-tutorial-ios7/
I am new to Objective-C and Cocoa and I am trying my way through some tutorials with some success. One task is troubling me. I am trying to create a root view controller that is a navigation controller as given by this tutorial:
http://fuelyourcoding.com/iphone-view-switching-tutorial/
On the second page that is pushed I would like the option to load a subview that is a TabBarController. Is this within iOS view guidelines. Is this possible? If so, could someone give some code snippets and explain necessary instantiations and connections in IB? Your help is appreciated in advance!
No, you should not push a UITabBarController to a UINavigationController stack.
Perhaps tell us what you're trying to accomplish and someone can suggest an alternative.
From Apple's View Controller Programming Guide - Tab Bar Controllers:
Note: Although a navigation controller
can be embedded inside a tab, the
reverse is not true. Presenting a tab
bar interface from within a navigation
interface is potentially confusing for
users. A navigation interface uses one
or more custom view controllers to
present an interface focused on one
goal, which is usually the management
of a specific type of data. By
contrast, the tabs of a tab bar
interface can reflect completely
different purposes in an application
and need not be related in any way. In
addition, pushing a tab bar controller
on a navigation stack would cause the
tabs to be displayed for that screen
only and not for any others.
I cannot answer your question directly, but in my app I have a UITabBarController which displays multiple UINavigationControllers and other types of controllers. So I think you may have it the wrong way around. In other words, create a project which uses a UITabbarController as the base controller and when you select a tab, load up the corresponding UINavigationController (or other type of controller) as necessary.
I am trying to build an iPad app set-up as a split-view, but on the detail page being able to drill down like a navigation controller.
An example of this working is the setting app on the iPad where if you select the 'General' tab you can then drill down on the detail page from say general > network > VPN
Any help or tips on this would be great. I thought it might be two navigation controllers on the root nib, but couldn't get this working.
you mean like General -> About ->.. (in ipad simulator) right .
if all your detail view needs the TableView, then its better to make your detailviewcontroller as the subclass of UITableViewCOntroller.
OR If you need different views when click on the cells of rootcontroller(left pane)
Create a method in DetailViewController say setDetailView{}. And call this method when click on the cell of RootController
inside this method,
remove all subviews from detailview
create UITableView and set its delegates
on tableview didSelect method, we can push other UIViewController instance
[self.navigationController push...]
Hope it helps.
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).
