Even if at times it may get a bit lengthy, it will benefit you and your team in the long run providing for easier readability and code maintenance. I encourage you to use descriptive names throughout your code. Name: A name we want to give to our outlet to reference the connection in our code. Since our label represents an acting task, let's keep it simple and name it actingTask:zorro. Object: A connecting object: our controller - View Controller - this is where we dragged it to. It already has Outlet selected - which is what we need. Let's review what's there:Ĭonnection: A type of connection we want to create. Most of the parameters are already pre-populated for us by Xcode, just a little left for us to complete. This popup contains the outlet's initial configuration.

An outlet configuration popup will appear: When you see " Insert Outlet or Outlet Collection", you can let go.

Through this connection we'll be able to access any property of that element in our code. Creating an OutletĪn Outlet is connection between a UI element (a label, a button, etc.) and the controller.

We need the second view at the moment - Assistant Editor. We won't use this option in this course). (This option assumes you are using a version control system. Version Editor: This view allows to open two versions of the same file to assess or revert the changes. One of the slots is considered a primary woking file and others - assisting files. When this view is chosen Xcode makes a guess which file would be the most relevant to the current one, and, displays it as an assisting file. A visual file - like storyboard or, a code file - like our controller file.Īssistant Editor: This is a split view that allows working with two or more files at the same time. This is a traditional view, it displays a single selected file. The options of this toolbar provide different layouts for the Editor panel in Xcode: Let's make it happen! Introducing Assistant ModeĪt this point we'll need to access 2 files at the same time: the storyboard and the controller file.Īt the top right corner of the Xcode interface you'll spot this toolbar:

Reference the label to display the new task to the user - that's called IBOutlet. To accommodate this, we'll create what's called IBAction in Xcode. In particular it needs to:ĭetect the button tap to generate a new acting task. This means our code needs to know about two UI elements: the label and the button.
