I have an application with a maybe-strange navigation scenario. I'll try to explain:
1) first scene: select an available item from a list
1.1) once selected, you navigate to a tab view allowing you to view/edit the various attributes
2) if the desired item isn't available, you may create a new one (by selecting a "+" bar button) which navigates to an alternate scene
2.1) there may be multiple scenes required to create the item, all scenes are simply pushed on the stack to allow the user to go back, select different options, etc.
2.2) once all scenes have been displayed and all attributes have been collected, the new "item" will be created and saved.
2.3) now, I want to automatically act as though the user selected this item from the beginning, that is, I want to pop all previous views off the stack and navigate directly into the tabs (step 1.1).
Does this make sense? Easy to do? Is there a better way to go about this? I'm using xCode 4.2 with storyboards.
Any guidance would be appreciated.
If you want (+) button on TabBar you should subclass UITabBar: Fo ex. TabBarPlus and set this class in storyboard.
But easier place (+) button on navigation bar.
The max number of displaying tabsart is 5 for iphone and 8 for ipad. If the there > number of tabs the last is "More" tab thet displaing list of other tubs in tableview. I you want displaying more tabs on tabbar then you should subclass UITabBar :)
If you want by back button on naigation bar switching beetwing Views that references with TabBar buttons you must create stack in code and hide backbutton of navigationbar and use castom left button of navigationbar.
The other navigation can be easy done in storyboard

I am working on a tab bar application. Is there a way I can programmatically hide one view controller from the scroll down list and from the "edit" list (but still be able to pop it on screen with a certain action, i.e. by calling its tabbarcontroller index)?
The problem is that I have now so many viewcontrollers that completely fill the "edit" screen. So I want to hide some of them and be able to trigger the hidden ones trough some action performed on one of the visible ones.
Thanks
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'm developing an iPhone application and i'm implementing the navigation among views with the UITabBarController.
The documentation says :
"The tab bar has limited space for
displaying your custom items. If you
add six or more custom view
controllers to a tab bar controller,
the tab bar controller displays only
the first four items plus the standard
More item on the tab bar. Tapping the
More item brings up a standard
interface for selecting the remaining
items. The interface for the standard
More item includes an Edit button that
allows the user to reconfigure the tab
bar. By default, the user is allowed
to rearrange all items on the tab bar.
If you do not want the user to modify
some items, though, you can remove the
appropriate view controllers from the
array in the
customizableViewControllers property."
Is there a way i can force the control to use exactly six icons without adding the "More ..." one?
You could subclass the object, and override its drawing properties, but it would most likely be rejected by Apple, as it is an inconsistant UI, and would go against the holy HIGs.
No, the tab bar will only accommodate up to five items. Once you add more than that you get four plus the more button showing.
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.
