I want to create a top bar with 5 labels. each label will show viewcontroller.
Can I create tabbar, add 5 viewcontroller, hide the tabbar, and each time press the top bar label, it will hide/show the correct viewcontroller through the tabbar functionality ?
if I'm wrong with this approach what do you recommend for this requierment ?
Thanks.
As far as I understand you, you need to use tabBarController.selectedIndex = (int)index; to change the selected tab. Please correct me if i misunderstand you

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'm using a tab bar view controller with more than 5 items and it's showing as the fifth item an item named "More". I want to avoid that item and make the scrollable tab bar.

I don't think you can subclass UITabBar and get what you want.
You probably need to create this as a custom UI object. You could create it using a UIScrollview.
If you are a beginner then this is likely over your head.
I know this is old but maybe you could add a UIView to a Tab Bar Controllers scene (not the actual controller) and then add a UICollectionView on top of that same UIView of yours to create a custom Tab Bar. You would have to change the size and flow layout for the collection view but other than that if you are familiar with switch statements and delegates I don't see why it couldn't work!
I want to add more than two UIBarButtonItems using the XIB. I know how to do this programatically. But shouldn't it be possible via the XIB as well? Not worrying about the ascetic of the app. Just want to know if its feasible.
You have to add the UIBarButtons in an the XIB and show them like this.
Yes you can , after trying ....
EDIT :
Please see the following method ,
In a UINavigation Object you can add only two bar buttons via nib:
Left Bar button and Right bar button.
You cannot add any Flexible Space Bar Button Item.
Simply add buttons with flexible space in between them, more than 4 will really look bad but you can give a try.
Thanks for reading my question!
I have a 5-part tabbar which I use for app navigation, the center tab is covered by a UIButton and is slightly larger (much like the instagram app). This works fine.
But what I want is the far right tab bar item to show a overlaying menu when clicked. I don't want it to switch to a viewcontroller with a menu. I want the menu to be displayed no matter which of the other views you're in at the moment. So I want it to act much like a button which is in the tabbar. But I have no idea how to go about doing this.
Should I use a overlaying button over the tabbaritem or should I catch the tabbarclick, but how can I prevent the view from changing in that case?
Thanks you for any help!
You need to implement UITabBarDelegate. Then override tabBar:didSelectItem: and implement your custom displaying here. See below for reference
http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UITabBarDelegate_Protocol/Reference/Reference.html
Then i would just make a custom UIView and fade it in when that specific tagged UITabBarItem is pressed.
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
