I have a iPhone app which uses TabBar in Navigation controller. I have a requirement like give a option to user to customize the tab order from settings panel from my app.
Save and reloading of tabs is done perfectly.Can we invoke default tab manager from code.
Please advice on how can we use default tabs manager to display from App setting screen.
Thanks
it is not possible to invoke default Tab bar edit screen. Instead we should create our own View-Controller to do the same work for us.

I have a bottom navigation bar with 5 tabs, In each tab I have a button that navigates to another separate screen using Navigation.pushNamed()(page 2); and from (page 2) I pop the screen, now the tab from where I navigated from need to be reloaded. because i store some data (page 2) and stored in sqflite i need to display the data in one of the tabs. Is it possible to reload a particular tab of a bottom navigation bar?
I tried using Navigator.pop(context,true) that also didnt work. Can some one help me with this, thanks in advance.
this is done by the provider. I'm new to flutter as well but this guy explained it very well!
Flutter by default does not save state (and disposes the widgets). If you want to save the state of a tab, you can use a PageStorageBucket. It is really well described in this tutorial:

I have a tab bar for my app. One of the tab is an "action" tab for which I would like to use the official iPhone compose icon here as the tab item icon, is it allowed?
It is allowed provided you use it they way it was intended to be used. So if it is used to initiate a "compose" feature it would be allowed.
Apple will not hesitate to reject an app if any of their icons are used in unintended or nonstandard ways - and will site their HIG. So if you aren't sure, I would suggest just creating something very similar yourself.
The compose item is a bar button system item, not a tab bar item. I think you will run into HIG issues with it - it is typically used to summon a modal controller for you to create an item (usually a message).
That doesn't really fit as a tab bar item, which suggests a view of information that you can switch into or out of at any time.
In addition, the graphic may not be in the correct proportion or have the right properties to use in a tab bar.
Is it possible to control a tab icon?
over tab settings?
over an API?
Why I'm asking: I'm trying to implement top company information into tabs. It's just one application. I can manually change the icon if I create a new application for each tab.
Is it possible to create one application that controls loaded iframe URL and change the icon from tab settings?
I don't think this is possible. Have a look at the tabs section in the page document, you can only update three parameters: position, custom_name and is_non_connection_landing_tab
I'm using Appcelerator Titanium to build an iPhone app. I currently have a tabGroup control that links to the major sections of the app, including the home screen.
What I'd like to do is remove the "Home" tab only from the navigation, without removing it from the tabGroup object. So, for example, I'd still be able to call tabGroup.setActiveTab(0) and it would take me to the home screen, but the tabs at the bottom wouldn't have a "home" button.
Is this even possible? If so, how can I do it?
Notes: I do not want to hide the whole bar, just a single tab. I also do not want to remove the screen from the underlying object, just the navigation UI. Also, I'm only developing for iPhone and don't care if other platforms aren't supported, so iPhone-only solutions are acceptable.
take the home screen out of the tab group completely and manage displaying it and transitioning to it separately; in the end, it will be a cleaner solution.
Have you tried tab.hide() or when creating the tab setting it to visible: 0?
I want to use two different uitabbar control in the application. first UITABbar control i add in the starting windows. and in this after the navigation i want to show the other tab bar with 5 tabs. can any one suggest how i do this ?
Or we need to add a different window for add this and need to show this windows on the click or other?
Please suggest.
Thanks
The Human Interface Guidelines specifically recommend against having multiple tab bars in your application:
If your application provides different
perspectives on the same set of data,
or different subtasks related to the
overall function of the application,
you might want to use a tab bar. A tab
bar appears at the bottom edge of the
screen.
A tab bar gives users the ability to switch among different modes or
views in an application, and users
should be able to access these modes
from everywhere in the application.
However, a tab bar should never be
used as a toolbar, which contains
buttons that act on elements in the
current mode (see “Toolbars” for more
information on toolbars).
If you need to have context-specific actions, use a toolbar instead.
