In my iOS application I have a login page that leads to the main pages. You can navigate between these pages with a tab bar. On each of these pages you can log out and return to the login page using the dismiss function. I wanted to know if by doing this I was leaving some controllers in a vacuum without having unloaded them.
For example, if I log in, go to the second tab and log out, will the first tab be unloaded?
And more broadly how does navigation with a tab bar work if it's not a stack?
On successfull login change root of application to TabBarController.When user kill application and launch again then set root according to the login status of a user. And when user logout from application then again change root to login controller.

i added a couple of html files to my Vaadin project layout. These files are "interconnected" with each other via anchors. In browser i can navigate to them w/o any problems, but in Vaadin app after click on link i see the following:
The view could not be found You tried to navigate to a view ('')
that does not exist.
After that my address bar in browser contains the follwing address:
http://127.0.0.1:8090/page3.html
How should i handle the navigation in Vaadin?
It seems that you use the Navigator to navigate to your html pages. With the Navigator you can only navigate to Vaadin Views, that are registered using addView(..), not arbitrary html pages. To do that use Page.getCurrent().setLocation(<your url>).
I am developing ios application by xamarin. For navigation in my app I use MvvmCross nuget and ShowViewModel method in my viewmodel.
I have listview, that navigate for children page after click at item. But at time navigation from page to page - second page is overlapping first and in result I have next situation:

I am working on Worklight version 6.1.I have created a Worklight project, added a Hybrid app and then added the iPhone environment to that application.I have generated Xcode environment and have added controller classes to that Xcode project.I have to add worklight Tab bar in my application.I am having html (web) page as the first page and from there I am navigating to view controller page.Added below function in main.js.
var tb = WL.TabBar;
tb.init();
tb.addItem("One", function () {
} ,"First", { image : ""});
tb.setVisible(true);
tb.setSelectedItem("One");
I am able to get the Tab bar items in web page.But Tab bar is not showing in any of the view controller screen.What I should do to have Worklight Tab Bar both in web and Native ios Screen.Help me to solve this.
Worklight uses Cordova, so when you launch your application what you see is the generated Cordova Web View by Worklight.
When you navigate to a native page (in your case, a new Class), you are essentially moving away from the Web View and into another View Controller, so you will not see the WL.TabBar instance in that View Controller (the tabbar belongs to the other one).
The following blog post contains background information on the architecture of a Worklight app and explains how to combine native controllers, such as a tabbar, in Cordova-based apps. Read it thoroughly and implement accordingly:
Combining native and web controls in Cordova based applications
For Web, use the Worklight Tab bar control -- as you have already done it.
For Native, you have to design a tab in the native code.
As suggested by #Idan, afterwards you have to establish communication/interaction between.

If you are using worklight ,you can integrate both native and web codes,but it is bit tricky,and difficult to handle all the controls from native to web pages,and loading different pages onclick of tabs.
It is better to implement custom web tab bar look like native tab bar.
You can design custom tab bar in web more similar to native.
I have a requirement to create a ipad app that supports tab to view content. I have created a custom splitview controller, whenever user goes to a particular section in the left section, the contents related to that will be displayed in the content view(right view). If a user selects a particular link in that content view it should open a tab and display the contents of that link in that new view. Similar to Web Browser tabs i need to handle tabs in this app. Please suggest any available open source component or any ideas to implement tabbing inside a ipad app.
You can use Three20 for your tab purpose. Also there are many open Source components available. You just need to search in google.
