![]() You probably don’t want to keep it there forever, but for this demo, let’s just throw all of this code in AppDelegate.applicationDidFinishLaunching. Use Git staging to craft your next commit without leaving your code. Code and design your apps faster with enhanced code completion, interactive previews, and live animations. We can get a pointer to the system-wide one by saying NSStatusBar.system. Download Xcode 15 Xcode 15 enables you to develop, test, and distribute apps for all Apple platforms. The Cocoa class that represents the Menu Bar as a whole is NSStatusBar. Add an NSStatusItem to the system NSStatusBar Type anything you like into the Product Name field, and don’t worry about any of the other options besides ensuring that Language is set to Swift. Choose macOS > Cocoa App from the template menu: Launch Xcode, then pick Create a new Xcode project from the splash screen. If you don’t have an existing macOS project you want to modify, start by creating a new one: Let’s take a look at how to add our own menu bar extra. This area is the thing I’ve been mistakenly calling the “system tray” for the past several years. “Menu Bar Extras” are what Apple calls those little icons in the upper right of the desktop next to the clock. The Apple Dev Center docs explain all of this, but it took me a little while to piece it all together, so here’s a single document with the whole process in one place. In the next chapter, you’ll learn how to lay out and configure the user interface without writing any code.In this post, I’ll give you a quick rundown of how to create a Menu Bar Extra for your macOS app. Then you looked at some of the basic pieces of the project, such as the main.m source file, and the nib file, and learned what objects are created and loaded from the nib file when the app launches. In this chapter you used Xcode to create a new project based on the Cocoa Application template and you built and ran the default app that the template defines. ![]() This object manages the app’s font menu, but you won’t use it in this example. You’ll then add some existing files to the new target. This message gives the delegate an opportunity to configure the user interface and perform other tasks before the app is displayed.Īn instance of NSFontManager (a dark blue cube) Xcode adds a new group and set of starter files for the macOS app, along with the scheme needed to build and run the app. When the app object has completed its setup, it sends its delegate an applicationDidFinishLaunching: message. This object is the window with a plain gray background that you see when the app launches.Īn instance of AppDelegate (a dark blue cube), set to be the app object’s delegate This object is the app’s main menu displayed in the menu bar. Below the line are objects created as part of the nib file: Above the line are placeholders-objects that are not created as part of the nib file itself, but exist externally. The sidebar contains several items split into two groups by a dividing line. When a nib file is loaded, the objects it contains are instantiated. The main nib file, MainMenu.xib, usually contains the parts of your user interface, such as the menu bar and window, that are visible the entire time your app is running. Nib files are an archive of UI elements and other objects. The instance of the NSApplication class, called the app object, loads the main nib file when the app launches. You add your custom behavior and logic to the AppDelegate class and any other classes you create. ![]() The app delegate can also perform some app configuration tasks before the app is displayed. The window object provides a container for the app’s visible content and helps deliver events to other app objects. The main job of the app delegate is to provide a window you can access through its window property. ![]() ![]() In this tutorial, the singleton instance of this class is referred to as the app delegate. The call to the NSApplicationMain function creates an instance of the NSApplication class and an instance of the AppDelegate class, which is provided for you by the Cocoa Application template. Xcode opens the source file in the editor area of the window, which should look similar to this: ![]()
