How to segue modal without losing tab bar controller - iphone

Okay, so I want to be able to have a TabBar Controller with two Tabs (like the template in Xcode), but inside the Second tab, I want to have a button that takes the view to a Third View Controller. I want the Third View Controller to have a back button to the Second Tab, I don't want the Third View to retain the TabBar, but when I go back to the Second Tab I want the TabBar to return.
So this is what I actually did, and it doesn't work. I put a button in 2nd view and 3rd view, and I control clicked and dragged to the respective views, and clicked modal. Everything works, except when I go back to the 2nd view I lose the tab bar.
Pictures of what I am talking about:

You don't need a separate modal Segue back to the Second View Controller, you can just dismiss the modal view controller when "Back to Second View" is clicked
[self dismissModalViewControllerAnimated:YES];

Navigation bar object in xcode 5 not showing back button and has no functionality

I have been trying to properly setup a navigation bar in one of my View Controllers for an hour now and have not found any working solutions.
I control-clicked on a button on my app's initial view controller(1st VC) and dragged to another view controller(2nd VC) and selected "modal" as the action segue.
I then added a navigation bar item to my 2nd view controller.
When I run my app on my iPhone, I can tap on the button on my app's initial screen and it will take me to my 2nd VC, and the 2nd VC does display the navigation bar, but the navigation bar does not have the default iOS 7 back arrow to let me go back to the app's initial VC.
I was under the impression that this could be setup exactly like I did above and that the back button functionality would be included by default.
Am I completely lost? Do I need to further customize navigation bar programmatically or with a tick box in the attributes inspector? Is "modal" the wrong action segue option?
I basically just want to have navigation bars at the top of a couple of my VC's so that the user can easily get back to the app's initial screen.
Thanks for the help.
Since you are presenting your second screen (2nd VC) as MODAL from your first screen (1st VC), you will not see the back arrow button on navigation bar. Your understanding about back button works for Navigation view controllers (push segue). For MODAL you need to put a cancel button on second VC's Nav bar and put a dismiss action for that.

Modal flip in tab bar tab, only the view, storyboarding

I have a tab bar with five tabs.
In one tab I have a mapview. I have an info button in the bottom right hand corner of the map. When a user clicks the info button, I want the mapview to flip to a view that has information about the mapview. I'd like a back button in the nav bar to flip back.
How can I do that?
I've managed to create a view controller and make a modal segue, but it doesn't keep the tab bar with it. Worse still, I created a back button on the flipside-viewcontroller with a modal segue back to the mapviewcontroller, and when you go back, the tabbar is gone!
I'm using a storyboard, and most tutorials I find use nibs and xibs. The more control-clicking I can do through the storyboard-IB and the less code the better. Any help is appreciated!
Once you have created in the backButton in the MapInformation view in storyboard, you can add the following to your MapInformation.h/m:
MapInformation.h:
-(IBAction)backButton:(id)sender;
MapInformation.m:
-(IBAction)backButton:(id)sender
{
[self.presentingViewController dismissModalViewControllerAnimated:YES];
}
After that, make sure to connect your IBAction in your storyboard(control-clicking).

iPhone, is it possible to remove the back button and make a view slide up?

I have a view which I'm reusing (its a date range selection screen) it elsewhere in my app, its the only view and there isn't any other views to navigate too. So theres no back button.
I'm trying to reuse the screen to select a date range in another part of my app. I call it from a done button on the previous view. However, I'd rather it appeared like a dialog. Also my title is too big and if I have a back button it doesn't fit.
So can i remove the back button, is my main question?
Also can i make the view slide up from the bottom of the screen ?
You can present the view modally by putting it in another view controller and having it slide up from the bottom of the screen like so:
[self presentModalViewController:modalViewController animated:YES];
The default is sliding up but you can change it with the modalTransitionStyle property of the modal view controller.
Using a modal presentation may fix your first problem as well, since you will need a whole view controller rather than just the view and it will cover the entire screen.

Invisible back button when view controller pushed onto navigation controller

I'm using a navigation controller to drill into a detail view when a cell is tapped. When I push my view controller onto the navigation controllers stack, I expect to see a back button that I can tap to pop the previous view off the stack.
The issue is that the back button isn't visible, but when tapping where it should be returns me to the previous view. What's the problem?
Ensure you have set a title for the master view - for example in viewDidLoad add this -
self.title = #"The Title";
Weirdly, if there is no title for the parent view controller on the stack, rather than show an empty back button, the iPhone will not display a button but will allow taps on the area where it should be.
This bugged me for a long time!
At least as of iPhone 3.0, you can also avoid the dreaded invisible back button by setting a title on the root controller's navigation item in your main window's nib (MainWindow.xib in wizard-generated projects).
Lets see if this helps you.
I had the same issue where I used a navigation based application and set up my search, rotation etc..
BUT, when I clicked on the table cell I was directed to the next view but that view did not have a back button present.
I tried to add a title to the back button but that did not work so this is what I did.
I opened the mainWindow.xib file and added a Bar Button Item to the group of other items inisde the window (where the file's owner is located). I then assigned an image to the button (you can add text here if you want).
Then I clicked on the Navigation Item and hit command 2 to open up the Navigation item connections
and chose the back bar button item and dragged it to the bar button item I wanted to use for my back button. And there you have it.

How do you create an invisible button that covers the whole screen including navigation controller?

I have a simple tableview that navigates to a detailed view with a navigation controller. In the detailed view I need to create a button which when pressed isolates all other buttons displayed on the screen including the navigation controller back button. I know how to get the invisible button to cover most of buttons the screen but I can't get it to cover the navigation controller back button as this has been created in the parent view. How do I pop it over the top of the navigation controller from the detail view?
You can insert the button as a direct subview of the key window.
[[UIApplication sharedApplication].keyWindow addSubview:theButton];
(why not use an UIAlertView or UIActionSheet?)
