Since there’s nothing particular to do with the text field’s value, we just print it on the console. To wrap text first enable wrapping through the Use the lineBreakMode property to truncate text. TextField.allowsEditingTextAttributes = true
Changing editable and selectable flags. Text field's background and text color. aceholderAttributedString = NSAttributedString(string: "Type something.", attributes: ) It's possible to have a placeholder with an attributed string as well. By doing so, the entire text or part of it can be formatted as per demand: Typed in text in text fields is plain, but you can have rich text as well by enabling the Rich Text check box.

If this behaviour is not appropriate for your app then simply feel free to turn it off. Preventing a text field from being editable though has as a result to convert it into a… label as we’ll see next!īy default all text fields support Undo actions, meaning that users can un-type whatever they’ve typed in by simply pressing Cmd + Z on the keyboard or using the Edit > Undo command on the main menu. Open the Behavior popup button to find all these options. However there might be times where you’ll want to make it non-editable, or at least just selectable. Once again, open the Line Break popup to choose between two wrapping options: Word Wrap (which is the default value applied), and Character Wrap.Īt this point feel free to revert the text field’s size and to delete the second text field from the view controller.Ī text field is by default editable, and you can see that in the Behavior field. So, select it and drag it into the view controller. You’ll get a few text field variations as results, but what we’re after here is a single Text Field control. Click on the Objects Library button in Xcode’s toolbar and search for a text field. At the time being there’s no content in the view controller, so let’s add a text field. In the starter Xcode project open the Main.storyboard file to reveal the Interface Builder. Instead we’ll focus only on the most important ones, those that are being usually set or are the most probable to be set. That would be totally pointless as there are so many of them, and usually not all properties need to be configured. Note that we won’t go through an exhaustive presentation of all available properties that text controls provide.

Still, there is a starter project for you to download with a few things already configured for you (such as a few IBOutlet properties). Instead, we’ll just be “throwing” text controls into a view controller and we’ll be discussing about their properties. On the contrary of the previous macOS programming tutorials, today we’re not going to build a small, fully working app focusing on the topic we have to explore. With that said, let’s dive in to our today topic.Įditor’s note: If you’re new to macOS programming, please check out the introductory tutorial here. I’m pretty sure that you’ll find topics and stuff that will attract your interest. If you haven’t read the previous posts on macOS programming yet I invite you to do so. And even though there’s not any kind of mystery or magic hidden and using them is relatively straightforward, a post dedicated to text controls is necessary so we have the chance to walk through their specific details and clear a few things out. Due to their purpose and their intended use, text controls are usually of the first ones developers use into an app. Labels, text fields and text views are types of UI controls that are met in every application, even if not all of them are present. I don’t think there’s ever existed a meaningful application without using any kind of text control. We are going to talk about text controls. Their primary purpose is to gather user input as well as to display certain message types to users. Today we are going to focus on a commonly used family of controls which are vital to every application. Welcome to another tutorial where we’ll keep exploring fundamental stuff on macOS programming world.
