When a go from a viewController to a tabBarViewController (meaning one of the two view controllers that is one of the tabs), the tab bar does not appear. When I move between either of the view controllers that are in the tab Bar controller instead, the tab bar works properly and it appears. Why does the tab bar seem to break when moving between a tab bar view controller and a regular view controller?
Thanks.

when I created the UITableViewController within Modal Screen, I noticed that code refused to show on Navigation Bars with Title in the Modal Screen, but Full Screen has shows it with this code.
self.navigationItem.title = "Tip"
Do someone know any tricks that allow adding that Navigation Bar Title or Navigation Bar needs in Modal Screen supports.
Let me know if you know about this, thank you for helps. :)
If you have a navigation stack with one or more view controllers and one of those view controllers (let's call it A) presents a view controller B modally, B doesn't belong to the navigation stack. It is displayed by A rather than pushed onto the stack by the navigation controller.
If you want to show a navigation bar with your modal view controller, you have 2 options:
1.Add a navigation controller before the view controller you want to present modally:
Navigation Controller 1 -(root 1)-> View Controller A -(modal)-> Navigation Controller 2 -(root 2)-> View Controller B
Or, you can install a navigation bar at the top of the modal view controller.
If you just want a navigation bar for the sake of displaying a title, use option 2, otherwise, if you need a navigation stack, use option 1.
So I have this application where I have a view controller (which I want to appear first when the app starts) and a tab bar controller. I also have other navigation bar controllers that are in the tab bar controller. I want to place my view controller on top of the tab bar controller. Making the tab bar controller the parent of the view controller would be better though.
But take note, I do not want a tab bar item to represent the view controller and I want the tab bar to appear along with the view controller. I do not and would not want to use storyboards as much as possible. How can i achieve this?
I guess the simplest solution would be to use a screenshot of your tabBar and put it in your HomeViewController as a button. In this case you could use your HomeViewController as rootViewController and in the button action you set the TabBarController as the rootViewController.
Root = Home + Button
-->
Root = TabBar
Perhaps you need four buttons, if you want the correct tab to be selected.
I have a tab bar controller.
From one of the views i want to goto another view via a button, which i have done.
Once on that page i want to go back using the navigation bar.
This is the problem.
How do i get it to go back to the tab bar controller page?
Thanks

You can arrange your view controllers as follows:
Tab bar controller
Navigation Controller
View Controller 1 - button to go View Controller 2 using segue
View Controller 2
So, View Controller 2 will have a back button to go to its previous view controller.
I have an issue with a tab bar app. I am making a tab bar app with three bars on the bottom. On my my first bar it is a tableviewcontroller. When i ckick on the table view controller it takes me to a different view (which doesn't have the tab bar). When I clicked back to the home screen (which has the tab) the tab bar is gone.If you need a picture i will post it!
You may have set your UITableViewController segue to a modal style. If this is the case, you should change it to a push style.
In order for a push to work, your view controller needs to be in a UINavigationController. In your story board, select your root view controller and embed it into a Navigation Controller like this...
I have a navigation controller and a tab bar where I have buttons for multiple options. When a button is ever pressed it pushes its respective viewcontroller in navigation controller. That's fine, but when I again press the button in tab bar after loading any other suboption viewcontroller in navigation controller, it shows blank screen instead of that "options screen" which it shows when I touch it first time.
I am using this code:
[self.navigationController pushViewController:accountOptions animated:NO];
You're pushing same view controller twice without ever poping it from navigation controller.
You can either pop view controller when switching to another one or push view controllers once on navigation controller in tab bar and be done with it.
