So, Ctrl+Drag from the “Go to Other View Controller” button, to somewhere in the second View Controller. Well, in addition to that, Ctrl+dragging also helps set up segues.
Remember Ctrl+Dragging from last time? There we used it to make outlets and actions in our code. Change the text of the label to “The counter was tapped ? times.” This will make it easier to size it large enough to show at least a 3 digit number without having to make the label bigger. The label will show the number generated in the previous view controller. In this new View Controller, let’s put in a label. Drop it somewhere to the right of your existing “View Controller”. When your cursor goes over the main editor area, the description will balloon up to show another big box similar to the one you already have in the editor. Next, from the Object library, drag out a “View Controller” object. We could use a textfield, but then we’d have to deal with hiding the keyboard when done, and that issue should probably have a post of its own.įor the other button, you can change it to whatever you want, but for the purposes of this tutorial, I suggest to name it verbosely: “Go to Other View Controller”.
When we go to the other view controller, we’ll send that number to the other view controller to display there. We will click that one and increase its number each time. For the one to make data, change that one’s text to the numeral “0”. One is going to be used to generate some data for us, while the other one will send us to the other View Controller. On our initial View Controller let’s drag out 2 buttons.

Of course don’t do that for an actual app after initial prototyping, but for now, let’s just look into how to use segues. If you want to be lazy though, you can put any controls into the top left corner to make sure they will appear onscreen for an iPhone. If you want though, you are certainly welcome to set them yourself. Let’s leave Auto Layout and Size Classes on, but I’m not going to cover where to pin or align things like I did last time. Unlike the last tutorial though, we’re not going to mess with Auto Layout here. If you need help setting up an Xcode project, please see the previous post “Hello World! Your first iOS App in Swift”. That’s what we’re going to go over today, as well as one of the simple ways to share data between view controllers. Perhaps you want a way to segue into the next screen? As fancy as it was, you probably want more than one screen in your app, right? The sender parameter refer to the object which initiated this segue, we put 'self' to indicate that this segue is initiated by the InputViewController.So, last time we learned how to make a simple Hello World app on a single view controller.
This method tells the InputViewController to perform a segue to DisplayViewController. When the Next button is tapped, we will tell the InputViewController to perform the segue. Usually my naming convention will be "sourceVCtoDestinationVC". Then select the segue between view controller, and set an identifier for it, we will use this identifier on the next step.

After releasing the mouse click, select ' Show' inside Manual Segue. Link the InputViewController to DisplayViewController by clicking the yellow round icon on top of InputViewController, then press and hold control and drag it to DisplayViewController. Segue, in prepareForSegue method (Forward)Īssume you have two view controller set up in storyboard like this,.This post will show you 3 ways to do it and discuss when to use them. So now you have set up different view controllers in the storyboard and wanting to pass the input data gotten from one view controller to another for display purpose or processing.
