I have an UITabBarController which has 5 Tabs. So, my problem is, i want to make an welcome screen into the UITabBarController, but this screen should be just only one time visible, when the app started. After the screen appears and the user switch the Tabs, he can't go back to the welcome screen, otherwise he must quit the app and open it again.
I tried to make an UIViewController as an RootViewController, but he dont show me the UITabBarController instead.
Is there any way that i can solve this problem over the storyboard? Also with code it will be also okay.
If I did not misunderstand your question these ideas will help you;
Add an extra tab to your tabBarViewController , make it welcome view and make this view controller initial VC so user when landing to tabBarViewController this view will appear after few seconds change tab index selectedIndex as you desire from UITabBarViewController then hide welcome view button from tabBar.
Seond way : Inside UItabbarViewController create custom tabbarView (scrollable) you can use collectionView it's easy to implement and it cells selectable like buttons. Hide original tabbar make welcome view appears first, make its index sixth then change selectedIndex programmatically when you need and disable scrolling from collectionView with this way only your five buttons appears on screen and welcome view button automatically remain out of screen.
You can find example code in my Github repo UICWaveTabBar, UICSlideTabBar , UICExapandableTabBar
Fist link including .xib file, you can edit it from storyboard, second and third only code

I would like to develop a ipad apps which has a menu at the top of the screen as well as at the bottom.
There are four buttons on the top of the screen, and there are 10+ buttons at the bottom tab bar, which can be scrolled horizontally.
How can I write the root view controller as a framework for this operation?
Should I customize the UIViewController class or UITabBarViewController?
Thanks
EDIT:
Sorry for being unclear. Let me restate my question.
Actually my app will have the following hierarchy.
'Front Page' is simply a page (view controller) for user to choose language. After choosing the language, 'Menu Page' view controller is displayed.
Starting from Menu page and ALL view controllers (VC) in below, the page layout is something like this.
As you can see, there are top menu and bottom menu. Clicking on the buttons the app will quickly jump to the corresponding view controller (3rd level in the tree, VC1,VC2,VC3 etc) . And for every view, there is a BACK button on every page, clicking which will back to the parent view controller.
I was thinking to implement this by using a tab bar view controller and a navigation view controller but I still do not have a clear idea how to implement this.
Or maybe should I just use the navigation view controller and hide the top tool bar except the back button, and display an overlay UIView as menu which is on top of all other UIViews.
Can somebody help me? Thanks.
Since this is the outermost container for my app I hope to do it properly at start..
Sorry for my long question.
If you really want to develop a framework for this logic .You need to create Manager, ViewController, View, DAO ,Model and other classes according to your needs.
I assume you want to add the buttons dynamically to the tabbar (and if it scrollable , it must be a scrollview).You can use Toolbar for upper view but then it won't be in sync with the bottom-view(visually).In that case you will have to create your own customized views to look like a tabbar.
The manager will basically keep a track of all the buttons and different states of events and action on the views and the same information can be accessed via a static method form the viewcontroller.
Well you have not detailed on your needs , so it's difficult to predict the entire architecture.
You need a container view controller to manage selection of VC's 1-4.
clicking which will back to the parent view controller
Parent view controller is used to mean the container vc in a container view controller scheme - I'm not sure that's what you mean in this comment. Where exactly does the back button go?
See this link for more info about container VC's.
https://developer.apple.com/library/ios/featuredarticles/ViewControllerPGforiPhoneOS/CreatingCustomContainerViewControllers/CreatingCustomContainerViewControllers.html
You should be able to embed a tab bar controller in the content view of the container VC. Should be able to but it might be really buggy if there is a lot of communication between the child vc's.
The hard part is the back button. Basically it must be a button that goes back to VC 1-4 depending on which section you are in. The easiest way to do it is to make sure that when you cycle view controllers, pass the back button information as to which VC is the current child so it knows which VC to navigate to when you press it.
I have created a Windows application.in my appdelegate I have called a controller class named analogcontroller and added this class to my window so that when I run my application the page that should come first is this page that contains an analog clock with five tabbaritems in it each calling different class.
So in the analog controller class xib I have added a tabbar with 5 tabbaritems in it. But when I run my application the page that gets opened is the page of the firsttabbaritem instead of analogcontroller. I want that when I run my application my xib of analog controller should be called with 5 tabbar items below it and when I click on particular tabbaritem then only its corresponding page should be opened, otherwise not. How is this possible?
you can set tabbar selected index to your desired tab index it starts from 0
you can write something like tabbarcontroller.tabbar.selectedindex =1;
Forgive syntax errors... you should try this. xCode is rich editor.
If you have a visible tabBarController, then something will necessarily be selected. No way around this.
However, if you would like to hide the tabBar, then you can certainly do that, either by setting its hidden property to YES or by presenting a modal view on top of the selected tab (e.g. the first viewController).

I have 6 view controllers on a UITabBarController. Each of them has a UINavigationBar at the top of them (Not linked to a UINavigationController), for showing the title of that view controller, and some buttons for controlling it. This was fine while I had 5 controllers, as no 'More' button would appear, but when I add a 6th, the more button appears. The tabs under that end up having two UINavigationBars! One is the one I added, with my title, the other is created by the TabBar and has a 'Back' arrow to go back to the more page. How can I fix this, either by merging them or otherwise?
Thanks, if you want screenshots just ask.
Here's a screenshot
The brown one is a UINavigationBar subclass I made, and added to the view in IB. The other one was added by the Tab Bar controller.
Yes you will need to merge them.As you need more tabs so More controller will apear and once you navigate in, it will put back button(more). In order to solve this and maintain your brown navigationBar you will need to use navigationController for those tabs in more(only for extras, not for all). This will put more(the back button) on your navigationBar.
But Remember In more you will have edit option also using which user can change position of tabs. So in that case this problem may reappear for other controllers. So please check if you can disable the editing of tabs(rearrangement). If not then you should think the same for other controllers also(in other tabs)
Thanks,
Ok, Followed all of your tips but no luck, until: I tested this https://stackoverflow.com/a/3397506/468868
Basically, you are right #Ravin, we must wrap the items in NavigationControllers, but after that, you must specify that:
- (void)viewDidLoad
{
self.navigationController.navigationBarHidden = YES;
}
Now, I just need to figure it out how to remove the navigationController from the "More" view
I'm developing an iPhone app with Objective-C and iOS SDK with a tab view on the bottom. I want to make the app so that when it first loads up, the tabs are on the bottom, but none of them are selected. Instead, the user is presented with a "home" view, and can select the tabs from there if he / she desires.
How would I make this work? I'm assuming it's something in the App Delegate?
Thanks!
I did this recently. Just do
[self.myTabBar setSelectedItem:nil];
Works perfectly, no tabs should be selected. Let me know if you have any problems. Also, just put that in either - (void) viewDidLoad or initWithNibName .
I think this would be something that's appropriate to fake.
I would:
Add a subview that overlays the area normally occupied by the selected tab view.
Add UITabBarControllerDelegate tabBarController:shouldSelectViewController that will hide/remove that view.
The only remaining problem is to make the actually selected tab button seem unselected until the subview is hidden.
I posted earlier but am running into similar problems again. Basically the way that my app is setup there is a top bar that is basically just a static image that has UIButtons placed on top of it. That is the Main View Controller and is persistent no matter what view is shown beneath it. I can't use a navigation controller because it is not possible to change the height and I need the bar to be significantly larger than a navbar. However my bar is functioning in much the same way. There is a "Home" Button, a "Back" Button and several destination buttons.
I understand how to switch views from say the home screen. My confusion comes with the back button. In order to press back the app is going to need to know what view is currently being displayed so that it can be removed from view and a new subview can be added. Ideally I would use the UINavigationController so that I can push and pop views which is really what I want to do here, however that is not possible because of the visual problem.
Does anybody know of a method that returns the current displayed view so I could do something like the following
[currentview.view removeFromSuperView];
[self.view insertSubview:experienceViewController.view atIndex:0]
You can use UINavigationController with the nav bar hidden. Put the nav controller inside a view that does have your jumbo toolbar and you'll have access to the push/pop behavior you're looking for.
