I created Tab Bar application and created one button at the first view controller. This button has action which open second view controller. Then second view controller is loaded, table bar disappeared.
How can I show table bar on all view controllers?
Describe it in details, please. I just start learning iOS application developing.

You will need a navigation controller in between tab bar controller and first view controller. First view controller should be the root view controller for the navigation controller.
And Secondly on button event you have to select segue type as below:
This will push the second viewcontroller from the first one and will also have the tab bar at the bottom.

I have tab bar controller with 3 tabs(all view controllers are embedded in navigation controller) while clicking the 3rd tab am showing a view controller with start button, clicking start it goes to the next controller, from this controller by programmatically am pushing to another vc. Now my issue is when I click the 3rd tab it showing the last pushed controller instead of showing a view controller with start button.
If I double click the 3rd tab it showing the current view controller.
Help much appreciated.
That’s how it is supposed to work, if you want to show the root vc for tab 3 you’ll need to call popToRootViewController() on the navigationController.
aVC.navigationController.popToRootViewController()
You would need to call the above when the relevant tab button is tapped, so you can use UITabBarControllerDelegate to find out when that happens.
Currently I have a tab bar controller that is connected to various navigation controllers like this:
I'm trying to navigate from one view controller to another view controller that is in a separate navigation controller. The only way I've been able to figure out how to keep the tab bar from disappearing is to create a modal segue to the original tab bar controller. The only problem doing this it automatically goes to the default tab bar viewcontroller and not the one I'm trying to reach.
I am very new to Xcode and have encountered an issue with my app. I am trying to create a tab bar app. On one of the tabs I have a button that brings the user to a different ViewController. I want to have it so the user can select a button that would return them to the tab that had the button. I tried to set up an action from the button to the previous view (the tabbed screen), however the tab bar disappears. I hope this is makes sense.
Here is a link to a screenshot...
Easiest way to do this is to place a UINavigationController as the root view controller of the TabBarController. You can do this in storyboard by simply ctrl+dragging from the tabbar controller to the navigation controller and adding it as a relationship.
Here's an example using storyboards:
The next step is to set the third controller (in this case the table view controller) to your player view controller class.
Then, you can use the default back button and animation that comes with the navigation controller. If you prefer to hide the navigation bar at the top of the screen, then you can use your custom back button to call
[self.navigationController popViewControllerAnimated:YES];
You can also choose custom animations / segues, etc. but using a navigation controller to help you navigate screens is probably the simplest approach.
I have created a new ios application using Single view application template in xcode 4.3 and added another view to that. In the first view i careated a command button as "show second view" and on second view i added a command buttion as "Show first view". I created a segue (of type push) from first view command buttion to second view.
When i click the "show second view" button from the first view, the second view comes up. But it comes up with the default navigation bar containing the default back buttion. I want to hide this navigation bar and present the second widow in full scrren without title bar. and when I click the "Show first view" on the second view I want to show the fist view.
How do I make it so the second view comes up but without the navigation bar?
You can hide navigation bar by messaging this -
[self.navigationController setNavigationBarHidden:TRUE]
A modalViewController might be better suited for this situation.
I have a storyboard setup as a Tabbed Application with first view controller containing a
UITableView. The Protoype cell has a "push" segue to detail view which is embedded in a navigation controller. So far so good. The detail view pushes when a cell is selected and there is a navigation bar item to get back to the table view.
Now I run into trouble. The detail view has 2 buttons "Map" and "Ticket". If I create a new UIViewController, embed it in a navigation controller, and ctril-drag a 'push' segue from a button to the new view controller as before, the app crashes instantly with a SIGABRT when I click the button. If I don't embed in nav controller and use a 'modal' segue instead it doesn't crash but it seems a natural flow to continue with the 'horizontal slide' animation and the nav bar button back to the detail view.
Once I can stop that crashing I would like to connect the other button to it's own view controller with a UIMapView.
What am I doing wrong?
You don't need to embed a navigation controller in the detail view. You only need one at the top level. Take out the navigation controller in the detail view controller and just do a push from there to the next view.
