Issue with pushing a segue - ios

I assigned a button to push a segue to another view controller but when I execute this part of the code I get the following:

Suggestions and thoughts?

You're trying to push from a UIViewController not being embed in a UINavigationController.
What you need to do is go to your storyboard, select the UIViewController you're trying to push from, go to the Editor menu, select Embed in, and Navigation Controller. Then you can push other UIViewControllers on it.
For information on navigation in iOS apps, read Apple's documentation.

You need a UINavigationController to embed your current view. Since Segues use navigation controllers to push other view controllers on top of it.
If you're using a storyboard, add a UINavigationController and embed your view in it.

You should add UINavigationControllers as your tabs, and use the ViewControllers (B) as roots for these navigation controllers. Only that way can you perform a push. Otherwise you have to use a modal presentation which will cover partially or entirely your Tab bar controller.

Do it in two steps.
btn_second: can post a notification that it has been pressed and then return to 'first'. 'first' receives the notification and sets a flag. In viewWillAppear, 'first' checks the flag and does a 'third' segue if it's set.

AMSlideMenu crash: Receiver (<MenuViewController: 0x10db0da10>) has no segue with identifier 'rightMenu'

I know there is already a question about this, but the answer provided did not solve my problem.
For start, I had 3 three segues pointing to 3 different view controllers and coming from the AMSlideMenuLeftTableViewController class. The first segue and view controller that I created was the view that appeared as the first view (the one that shows when the app loads).
However, since I deleted that first view my app crashes immediately after opening it up.
This is the crash log:

I think the problem is that the app is trying to display the view I deleted as the main view but it isn't there. The fact is that I have not found any reference to that old view I deleted.
If AMSlideMenu catches an exception when trying to create LeftMenu, it then tries to create RightMenu (I don't understand why, but is true).
In my case the left menu firstSegue pointed to a 'wrong view', because it was a simple view controller, not a navigation controller. I changed the view controller to a navigation controller (that points to my original view controller), and that fixed it.
Copy the AMSlideMenuWithoutStoryboard-Prefix.pch file settings to the PCH file from your project.

Unrecognized selector sent to instance, Storyboard bug after connecting a button to view controller

I was messing with my storyboard with no code involved and got this error after I connected "Terms of use" button to a view controller. It was working fine before this action.
-I created and connected a class to Terms of Use View Controller
-I used action push segue to connect

(Lame but I found the solution after I finished writing the question)
The reason for this error is I created an IBAction-UIButton method on touch up inside.
I deleted that code and hoped the traces were deleted.
It seems it wasnt, I had to unconnect the touch up inside by clicking the X in red squared spot.
I would try recreating the button and the segue, maybe you changed the IBOutlet name by accident or any other thing.

Unwind segue issue when navigating back to parent scene

I'm trying to unwind segue form a scene. It works fine but I need to get a value to the parent screen. (I use the push segue to navigate from parent to child scene)
I'm calling the unwind segue like this
- (IBAction)done:(UIStoryboardSegue *)segue {
NSLog(#"gonna navigate");
RESTToppingTableViewController *vc = [segue destinationViewController];
[self setSelectedToppings:[vc toppingList]];
NSLog(#"%#", [vc toppingList]);
}
But the issue is, it seems the toppingList array is removed from memory even before the parent view is called.
Below is the error I got.

What could be the possible fix? thanks for your time in advance.
I'm not sure but I think your destinationViewController isn't a RESTToppingTableViewController.
The log:
-[RESTAddToCartViewController toppingList]:
unrecognized selector sent to instance 0x9b681a0
states that you are trying to get the toppingList of a RESTAddToCartViewController but this controller has no toppingList property.
Make sure that the UIViewController returned by [segue destinationViewController] really is what you are expecting.
