I have an issue when I dragging and dropping from Assistant Editor to code button that button has automatically set Object to Exit but I need to set to View Controller. The issue is in the picture below. Is there any solution to solve it?
Issue in xCode
You could do this in two ways. When you are in the storyboard/xib screen the easiest approach is to hold the Ctrl key and at the same time select and drag from button to the assistant view. Do it like below:

By holding Ctrl, clicking on a button and dragging it to another view controller, it's possible to establish the segue to move view controllers. Once this segue is created, is this connection declared somewhere in the code or in the parameters list?
I'm opening someone else's project and I can only figure out which buttons are activating which segues by running the simulation and manually testing. When I go check the code or the segue's parameters, I can't find anything that would indicate which button is linked to which view controller transition.
In Main.storyboard, click on the viewcontroller that you are interested in inspecting. In the top right there is a right arrow that will show you all the segue relationships and outlets
.
You're using Storyboards, correct?
To exemplify:
You just need to:
(1): click on the specific ViewController,
(2): then click the Connections Inspector (2) - it's icon that has an arrow with a circle around it -,
(3): and finally you'll see all the related connections (3) to that specific ViewController. This applies to all UIView(s) as well.
I am creating an app that requires notifications. I created a settings page with a switch to toggle notifications for the application. I tried to link the switch to ViewController2 using an #IBAction, but it keeps connecting the object to Exit, instead of ViewController. I am getting really frustrated because the #IBAction won't stay connected. I am not sure what is going on, but if I could get help that would be amazing.
The images are linked down below to Imigur.
This is the connection to ViewController2
This is what occurs when I connect the IBAction to ViewController2
You can see there is no action option for the connection in this image.
When you attach #IBActions (or #IBOutlets), you do not want to attach them to Exit on the View Controller.
Follow these steps to add an #IBAction:
1) Make sure your View Controller's class is linked to your file, then go into the Assistant Editor making sure you selected Automatic.
2) Hold Control (^) and drag the button to your ViewController class.
3) Add the button as an #IBAction. - It's also recommended to use UIButton as the sender, instead of Any.
It should look like this:
If you have questions, let me know!
The problem might be that you are supposing you can form an action connection from a UISwitch in the scene of one view controller to a different view controller. You can't. You can form outlets and actions only between a view controller and the interface inside the same scene of the storyboard.
Click on the top bar of your problematic ViewController (the overview of what is getting displayed on screen), click the top left icon (called View Controller).
On the right click "Show The Identity Inspector" icon and you should see class. Change the text to 'ViewController'. Hopefully it should auto fill.
This will solve the problem.
I try to use Storyboard to link an NSToolbar to different View Controller through Triggered Segues. I want them all to be opened in the same Window Controller. Here is a screenshot:
Clicking on each NSToolbarItem opens a new window instead of the same Window Controller. Any idea how this can be done without coding?
Thanks for any help

Basically, what you need to do is to just use an NSTabViewController - Set it and your window content and also select what style you want your toolbar to have! See image.
I'm building an app right now and I have a problem with the combination of button and segmented control, if it's even possible.
Right now I have a segemented control, where you can chose between 7 different values. On the same page, I have a button leading to the next page. Now I want my button to lead to a different page, depending on the selected value in the segemented control.
My segemented control is located in my ViewController.swift and my button in Main.storyboard.
I looked in the code of it and found the destination of the first page the button has to lead to, but I can't figure out how to make it dependent on the segemented control. Simple "if" commands seems not to work in ".storyboard",
Could someone help me out?
not sure that you can do this from just the storyboard, I would have the button reference an IBAction in the view controller. The action could use a switch statement (or a series of if/else statements) to call different segues based on the state of the segmented control.
I am trying to write a project but with out success i need help:
in the first view i have UITableView with a + on the navigator bar than after i push on him
I open a another view there i want to add a first name and after then i click "Done" i want the name i wrote in the textfield will appears on the first view
and thats is my problem the name are not appears in the first view and i have not bug or error .
what can be missing in my project all the button are connected.
I need some help please.
Since you're not showing code, I have to have a pretty general description here. With a button in the nab bar (which is what I think you're talking about) the button calls an action method. Your action method is what moves you to the second view.
Even if your button is "wired up" correctly in your xib file, your action method may not be doing the right thing. I'd try setting a breakpoint in your action method to 1) see if it gets called and 2) step through to see if you're creating a new view and pushing it on the UINavigationController's stack.
