Create a modal view with navigation bar and back button

Question

I want to create a modal view with the navigation item (right view on my screenshot) and I want it to have a 'back button'. My app is TabBar application and I don't want this view to have a tab bar, but I want to load a previous view (left view on my screenshot) with a segue similar to the type "push". I can only create push segue to provide right navigation back to the view on the left, if it's loaded as a modal view, the NavigationBar & TabBar are gone. Any workarounds for this? Thanks in advance!

Answer 1

Just put a Navbar on the new view with a bar button item. Create an action for the bar button item by control dragging from the bar button item to the .h of the view controller. You can then use a delegate and protocol method to tell the first controller when the button has been pressed and have it use [self dismissModalViewControllerAnimated:YES];

So in your second view create a protocol with a method done, like this:

@protocol SecondViewControllerDelegate <NSObject>

-(void) done;

@end

@interface SecondViewController : UIViewController {
    ...
    id delegate;
}

...

@property (nonatomic, assign) id<SecondViewControllerDelegate> delegate;

-(IBAction)done:(id)sender;  //this will be linked to your nav bar button.
@end

then in your action from your button call this:

-(IBAction)done:(id)sender{
   [self.delegate done];
}

Your first view controller will need to implement the protocol <SecondViewControllerDelegate>

then in your first view controller, set it up as a delegate for your second view controller before you segue.

-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if([[segue identifier] isEqualToString:@"Second View Modal Segue Identifier"])
    {
        SecondViewController *viewController = segue.destinationViewController;
        viewController.delegate = self;
    }
}

lastly, catch the done call from the delegate in your first view controller:

-(void) done
{
    [self dismissModalViewControllerAnimated:YES];
}

That's how I have done it. If you don't have a lot of experience with protocols and delegates it may seem confusing at first, but it has worked well for me.

You will need to wrap your right hand side view controller in a new navigation controller. In IB, select it and choose the menu item Editor -> Embed In -> Navigation Controller and IB will show a nav bar which you can customize to your heart's content.
