I have a tab bar style application and once the user navigates into the application (selecting a tab bar), the tab bar is hidden using self.tabBarController?.tabBar.hidden = true in a viewDidLoad function
How can I reshow the tab bar later. I've tried self.tabBarController?.tabBar.hidden = false in both viewDidLoad and viewWillAppear.
There's a setting in the storyboard of the view controller that is going on the navigation stack:
if you check [x] Hide Bottom Bar on Push, the tab bar will be hidden when a view controller is pushed onto the navigation stack. It will also be unhidden when that view controller is removed (popped).

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.
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.
Okay so I have one main view controller and then I added a navigation view controller from the 'Editor -> Embed In -> Navigation Controller' toolbar and then I segued from the first view controller button to the empty navigation controller scene because if I segued directly to the signup or signin VC the main view controller would end up having a bar on the top like the navigation view controller. But now i added an bar button item "Back" and segued to the main VC and the bar comes back with a builtin back button. So how can i add a default back button or any back button without having the main VC becoming a navigation view controller.

The problem is that you have two navigation controllers when you should only have one.
You should make your initial view controller a UINavigationController, and set your previous initial view controller as the root. If you don't want to see the bar, just set the bar to be hidden on your viewWillAppear, and unhide it on the Sign In / Sign Up pages.
I have a navigation controller with a segue to a tab bar controller. When it pushes it creates a navigation bar with a back button. I've found code to hide the back button, but the navigation bar is still there. How do I get rid of the navigation bar?
Yes,

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.
