On my desktop when I create a Tab Bar application Interface Builder is not displaying it. On my laptop this is not the case.
The problem is kind of hard to explain so I made a video and posted it here.

Does anyone know if this behavior is normal?
You don't want to add your button to your window directly. You get the hierarchy wrong here.
You should add your button to the view of the UIViewController of one of your tabs.

In an iOS Tabbed Application I'm making, I've got tabs to load different viewControllers, which is pretty standard. What I'd like to do is make a few buttons (with images on them) load up another view with the button image maximized to the screen. However, I'm not really sure how to go about doing this. I don't want a new tab for this, I just want another view to show the full image, and then a button to return to the tabbed view. I've experimented a bit with making a subview to do this, and I've attempted to change the main viewport to the new view, with no success. If someone could point me in the right direction, and maybe give me a solid concept as a jumping-off point, I would really appreciate it.
And to clarify, I'm not looking for "the best way", per se. I'd be willing to accept a quick and dirty fix. But if you know of more than one way to handle this situation, I would appreciate whichever one you personally think is better.
I would do it by creating a UINavigationController to use as the primary tab view. When you want to show the full screen button, you create a new UIViewController subclass (below) and push it. That class will return YES for the method "hidesBottomBar" (its something like that).
This new view controller will be a traditional controller. You can create a UIImageView to fill the view (or you can probably replace the view with the imageView). In the viewDidLoad you'll set the UIImage of the view (or you can enter its name in the nib).
When someone clicks on the button, then you'll pop that view and return to your tabbed view (where the tab bar is showing).
I did something like this (not a big button), so I know the tab bar can be made to hide on the push. You can also hide the navigation bar so it never is even show (again, not 100% sure at the moment how to do it but its possible).
I need to make a toolbar on the bottom of the screen with some buttons. I want in every button to have a small image and a small text under it. The closest i can find from "Xcode" is the "Tab Bar" where you can put icons and text but the problem is that when you add an image you can only see the shadow of the image and not its colors.. Can i change that? Or is another way to make a toolbar like the one i am describing?
EDIT
I need the buttons to change controllers and i just noticed that i cant create actions for the tabs but only outlets. So i guess the tab bar is not what i should use. Any ideas for a toolbar?
Yes Tab Bar is the Best approach for it and it is very easy to customize the tab bar if u are using IO5
This LINK will be helpful.
There is another approach (which was applicable uptil IOS4 for customization of Tab bar) was to Create Custom buttons with tab bar look alike Images. it will give u the same feel, but like i said it is very easy now to customize IOS Tab bars
Here is a couple of Links for u
LINK 1 With Story BOARD
LINK 2 Without Storyboard
One More thing Try searching Google before Posting a question here if have some problem then feel free to post along with the code or tutorial u tried.
Let me know if i Worked
Cheers

I wonder if someone could help me please? I'm brand new to iOS and whilst I've been searching various sites for my answer, I'm afraid I haven't come across it yet but feel this could just be my naivety to the language so I apologise if this is a really simple thing...
I have a Tab Bar Controller with 3 views. On my first tab I have a button which when clicked, I want it to go to the 3rd tab (which is does). However, on the 3rd tab, I would like to insert a back button so that the user has the option of clicking back to go back to what is essentially the main menu of my application.
Can anyone tell me how I can do this please? I'm currently using storyboarding as I'm not very good with the language yet but any help would be greatly appreciated.
Thanks
Sean
You need to add a navigation bar to the view and set a bar button item with the action to change the tab.
Remember that a tab controller is standard across multiple apps, the user is use to tapping the tab to change the view rather than pressing buttons within the view.
It might be worth you looking into a UINavigationController
The first thing, you are implementing UITabBarController. you don't have to create a back button, because user can navigate between screens by tap on tab bar.
Second thing, you can use UINavigationController to manage you viewControllers,the Back button will automatically show when you push ViewController by method pushViewController:animated:
This is hard for me to explain, so please bear with me for a minute.
In Xcode, if it is in full screen mode, showing the app's menu also moves the toolbar down. I have tried to make an NSView move and resize whenever the menu bar is shown, but I cannot figure out how to do it. I think this has something to do with and event, because setting struts and springs in Xcode does not make it move automatically. Can anybody help me figure out what the event is?
Edit: I just re-thought my question, and I have to make a correction. NSToolbar does this on it's own. I want a normal NSView to move and resize itself when the window goes into full screen mode.
I think you might be having the same issue as I was - if so, you need to call [NSToolbar setFullScreenAccessoryView:] on the "accessory view" you want to glue to the bottom of the NSToolbar.
Note that in windowed mode, your accessory view should take up space in the NSWindow's contentView just like any other view, but when you enter fullscreen mode you'll want to remove the accessory view somehow since Cocoa rips it out of your layout and leaves a gap unless you account for that.
I can certainly understand this issue being difficult to explain without having the background knowledge - I had the same problem. :)

I'm quite confused with the whole animation stuff in iPhone SDK. I tried to study throught the SDK documentation, this website or tried googling it out without success.
I'm unable to get my scenario work.
I have single XIB file, with tab bar and a 4 tabs.
In a special event i want to switch from one page to another "in code", so I call eg: [tabController selectedIndex: 0].
I need this transition to be animated. Is there a way?
If user switches tabs manually, no animated transitions are needed
Also I have one subquestion:
In one of the tabs I have a UITableView with set of items. When user clicks any of these items, another set of items are beign shown (sort of hierarchy browser)
I tried to animate this transition using -deleteRowsAtIndexPaths:withRowAnimation: and -insertRowsAtIndexPaths:withRowAnimation:, but without luck.
Desired transition is shifting the old items set to the left side and the new items from the right side.
This is first time of my iPhone development, when I got lost even with all the forums and documentation. :)
Thanks in advance to anyone trying to help me!
As for your first question: Yes you can.
Try this link for some answer:
transition on tab bar sample code.
In short words: you should add a delegate object to handle the tab bar switching by setting the tabBarController.delegate = self.
Yet, what this forum post won't tell you is that you need to "import" some framework to do it.
First - right-click on the framework folder on the left hand list in Xcode and add an existing framework named: "QuartzCore.framework".
Than - add these lines to your tab bar holder (on .h file):
#import <QuartzCore/CAAnimation.h>
#import <QuartzCore/CAMediaTimingFunction.h>
As for your second question, try to replace the datasource (array or what ever) or create login function on the cell to replace its content.
Enjoy!
First Question: No, you can't animate tab switching. Please read Apple's Human Interface Guidelines on this. Tabs are meant to switch instantly. An animated transition would break the "tab" paradigm.
Second Question: When you tap on a row, the user does not expect other rows to disappear and new ones to appear. Instead, this sounds like a case for a UINavigationController. Please refer to Apple's sample code, specifically the UICatalog for sample code on how to implement this.
