I am using a tab bar (UITabBarController) on my app and I wish to have more than 20 different views to choose from.
If there are more than 5, "More" menu appears. I can access any of my views from "More" menu but I have problems with customizing my TabBar with "Configure" (Edit) navigation bar. I can see only 20 first view icons and I can't scroll the view any direction. Icon with numbers 21 or higher are unavailable in "Configure" (Edit) navigation bar
Is there a way to scroll up and down (or left and right) to be able to customize TabBar with all of my view icons? Is there the other way to customize "Configure" (Edit) navigation bar to get access to all view icons?
Looks like there is no solution for this :( except creating your own UITabBarController.
This is a limitation of the controller provided by Apple, but you can work around this problem as follows:
Catches the action of the edit button and replace it with your own action that aims to display a custom screen that plays differently the sort action.
I have done this way in my applications, when I had the need.

I'm working on an iphone application that has exactly 5 tab bar buttons.
I've created a custom tab bar and added 5 buttons to it, each with a separate view controller.
The buttons are showing fine, but the 5th view controller is not loading on 5th tab bar button press. This might be because the 5th button is supposed to be the "More" button. Is their some way to override it?
No the more button wil only show if you have more then 5 viewcontroller in the tabbarcontroller.
You can customize your tab bar to do so.
There're some exist ones, like the one below:

It works Excelent! And you'll see the screenshot that it use five tabs. :)
AS per apple human interface guidelines if you have more than 4 tabs last tab is displayed as more tab and you can not alter it
I have an interesting problem. I have an app that I'm developing that involves photos so screen space is at a premium. Also, using disappearing and reappearing nav / tool bar controllers (like in the camera app) doesn't make sense for me. In a perfect world, I'd use a UITabBar to switch between the 4 main navigational view controllers that my program implements, however I also am going to need space for a toolbar right on top of the tab bar most of the time. These two components take up too much space between the two of them so I need a way to save some space.
That's where I came up with the idea of using a toolbar to implement the functionality of both the TabBar and ToolBar. On the left side of the ToolBar would be the 4 buttons that allow access to my 4 main navigational view controllers. The one that is currently on the window would have it's button depressed. Then there would be a divider, and on the right side of the tool bar would be buttons specific to whatever view is currently on the window.
Anyhow, I'm just wondering if anyone has any clever ideas on how they'd implement this?
wat do u mean by left and right of toolbar??? adding a tab bar will not affect ur view size. when adding a toolbar, well yes it does affect ur view size.
my idea wolud be add a toolbar to the top of ur view and u can make it visible only when the user taps on the screen. until then keep the toolbar hidden. when the user clicks for the second time on the screen hide ur toolbar. this way u can have the whole view for ur pics and also have a toolbar for giving options.
I am working on a mobile version for my company's web app. The structure of this application requires uitableviews with a tab bar on the bottom and a navigation bar up top to return to the previous view. As you drill down in the application the tab bar items change at each level allowing selection of different views pertaining to that specific level in the app. I need a way to implement this with a navigation bar on top that navigates back to the previous screen on every tab in said tab bar when a back button is clicked on any of the tabs.
for example: let's say i start out with an items tab and a simple about tab. When i click items it drills down to a new view called subitems and the tabs for this view are subitems, favorites, details, and notes. I want the navigation bar to go back to the previous screen when i click the back button on any one of these four tabs.
Is this at all possible? I can't seem to find anything related to this type of structuring within an app. any help/examples would be greatly appreciated.
I know that a negative answer always sounds bad, but I tried to do the same a few months ago and I could not find a way of doing it using the standard UITabBarController/UITabBar. Take also a look at this question/answer.
The good news is that it is not that difficult to implement from scratch a tab bar controller that can be pushed on a navigation stack. There are also several examples around, one is BCTabBarController. GtabBar is another example.
I actually found a way to do it you just have to implement the navigation bar's leftbarbuttonitem instead of the traditional back button. Then I just created a method that is invoked when the back button is pushed this updates the navigation stacks of all four views within the tab bar and sets the tab bar items accordingly to match with the previous views we are navigating back to. . . so long story short...it is possible.
I am working on a project which involves both kind of applications ie Navigation based and Tab based. All things are working perfectly. But what I want is, when I click on a particular tab then a button must be added to the navigation bar at the top to edit the table below it. I am able to draw the button but it is not affecting the tableview below it. When I do this in navigation based application it works perfectly. But it does not work in tab based.
So please tell me the way to add button at navigation bar in UI tab based application which appear only at particular tab.
tell me the sample code or any tutorial for it.
For each tab embed a UINavigationConrtoller, and your own view controllers in them.
This way each tab will have its own navigation bar, and thus can have their own sets of bar items, titles, etc.
You generally never want to embed a UITabBarController in a UINavigationController, always the other way around.
I want to use Tabview for my whole app. However in certain view, I have more operations than I can fit in the navigator bar. So I thought of using Toolbar but toolbar should be located at the bottom, right? Toolbar looks weird to be on top of the tabview, and hiding tabview for one view doesn't really make sense. I guess I can go with more buttons in the main view, but any other alternatives?
What can one use to add more operation(s) to tabview?
Thanks
In regards to keeping the UI simple, Apple recommends using a "More" button on the tab bar to fit additional functionality in on a tableview or some other NIB.
Additionally, you could always have another NIB that is hidden unless they hit a certain area or button and then it pops into view for controls, options, etc.
