When I build even the most basic default Tabbed Bar application in swift I have to click two times on the tab bar icon to change to the next view. How do I change this to only be a single click? It wasn't always this way, but now when I create any sort of tab bar controller it behaves like this.

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 developing an app which Have three tab bar Items.
When i click the second tab bar item, then the search bar needs to be automatically enabled like(search bar becomeFirstResponder).
I have done this in viewWillAppear method. So every time it is automatically becoming first responder. But I want only when tab bar item is selected that search bar has to becomeFirstresponder.
can anyone help please?
You can use tabBarController: didSelectViewController: for identifying when specific tab is pressed. And from there you can call becomeFirstResponder.
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 wrote an app that uses UITabBarController, but if I add a lot of tabs it don't show me more button. Doesn't the UITabBarController creates this button automatically?
No - according to the documentation, you should not need to handle this yourself.
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.
Yes, you need to create it manually. The "fifth tab is more" is just a convention. It's up to you to create a UIView/UIViewController pair to manage your additional settings and map them to that fifth tab.
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.
