I have one problem, I have my first view controller and when i push a button to connect with my host to check if the user is registered.. but when i push the button the storyboard pass the next view and after check the user...
So i'm trying pushViewController with code, but i dont know how push a view that is inside the storyboard.
Here is the code : http://pastie.org/3025806
You have to connect the first view with the second view and choose push. It's important to connect the first view and the second view, NOT the Button and the second view.
Edit: I've read your question again. If you change that it will work. If you connect the button and the view controller the push action will be executed directly.
The following is just a tip ;o)
Click on segue, which links to the second view. You have to give a name to that segue so change the identifier name to something like "loginDone". (Open the right menu for that ;o))
Now you can do this after you checked your login form:
[self performSegueWithIdentifier:#"loginDone" sender:self];

How do I create a custom back button on one of my storyboards, when I do a segue and I say push it creates a back button on Mac with but when I do a modal or model it does not create a back button?
Modally presented view controllers do not automatically get close buttons.
self.navigationController.leftBarButtonItem = ...
A pushed view controller will automatically create a back button if the navigation controller is shown.
You will have to create your own back button. In the view controller that you have presented via the modal transition, you have to put a toolbar on it. Put it at the top and if using autolayout set the constraints top, both sides and height. Then place a barbuttonitem in the toolbar. You can select a system button like done or cancel. Make sure the new view controller is the class that you created. Now you can control drag from the barbuttonitem to your .h file and connect an IBAction. Call it dismiss or something like that. In that method call [self dismiss viewcontroller:animated completion:nil]. This will bring you back to the original view controller. I am not a my computer right now so I am not sure the exact wording of the dismiss method, but it will auto fill for you. Good luck.
As Douglas explained, you need to create property of the button (UIButton or BarButtonItem) and in the viewcontroller .m file connect
- (IBAction)backButton:(id)sender
{
[self dismissViewControllerAnimated:YES completion:nil];
}
with the button. This will dismiss the current view controller and bring you back to the previous one :)
I am trying to create a ver simple app in iOS 7. In this I need move back and forward using UIBarButtonItem. But when I am pressing back button it is loading a view but not showing all UI Controls properly basically the view is empty. in the below as I pressed any of the cell it will move to another view and load respective data.
On the pressing back button it should show earlier image but it is showing following view.
Please tell me where I am going wrong Thanks in advance.
It seems as if your second screen is presented modally. Then you need to make an unwind segue.
Add this code to the viewcontroller that should be returned to:
-(IBAction)backButtonUnwindSegue:(UIStoryboardSegue *)segue
{
}
then from your modal vc, in storyboard. Drag a segue from the "Back"-button to the Green "Exit"-icon and select the backButtonUnwindSegue-action

I just now figured out how to add a new view when you press a button. For example, in my storyboard, I am using a tabbed controller and in my first viewController i have a button in the top right corner on a navigation bar. and when i press that button, it directs to another view controller. I was wondering how I would be able to write the code for that view controller? I tried creating a new file > objective-c class, but I dont know how to link them together? any help?
If you've made that other controller in the storyboard, you just change the class of that controller to your new class that you made. You do this in the identity inspector.
Use navigation controller to navigate between your view's, You have to make an IBACTION method fot the button. In which you will navigate the view you want by pushviewcontroller.

How to push viewcontroller ( view controller )?
It implies that which class has to be initialized and what is the nib name of this class. We should not do anything in this block, until you need that your code to be executed before viewDidLoad/viewWillAppear.
Turns out that there is no code necessary to get a button to direct you to another view controller that you set up. You have to declare the button obviously in the #interface part, connect the button with it's code, and then you have to use an action connection from the button to the next view controller you want the button to activate. I have used a modal connection personally, mainly because I'm not sure what a push connection is or what it does... But Ya I figured it out! Hope this helps to any other people who need this!
I am stuck in my code. I can't make it to go to the other view when a user logins.
I have a class UILoginClass (Tableviewcontroller) And a class ImageViewController (viewcontroller).
Check image below.
I want to get from UILoginClass to ImageViewController but i can't make it. Anyone help?
1) Create a "push" segue from the view controller of the login screen to the image view controller (press ctrl and drag from source view controller icon to the destination view controller).
2) Give that segue an identifier (click on the seque in IB --> attributes inspector --> identifier. It is just a string identifier that allows you to initiate that segue when you want to.
3) In code, when the login is validated, call performSegueWithIdentifier:sender: with the identifier you gave to the segue.
It sounds like what you want is a push segue from Login Class to Image View Controller. In the Xcode storyboard you add a segue by ctrl-clicking in the source and dragging to the destination. Be sure to give the segue a name. Then in the Login Class you can call the UIViewController method performSegueWithIdentifier:sender:.
Oh, and you can get rid of the push segue from your navigation controller to Image View Controller.
I've got a "settings" type view that I want to be reachable by every view within my tab navigation. I am able to get to the settings view, but how do I program a button that brings you back to the view that brought you there? For example, if I access the settings view from view 1 I want the back button to bring you back to view 1. Then if I access it from view 2, I want the same back button to bring you back to view 2.
Thanks!
Is your view in a navigation controller? If so, use:
[self.navigationController popViewControllerAnimated:YES];
If it's a modal view controller, use:
[self dismissModalViewControllerAnimated:YES];
