Finder Sync
In OS X, the Finder Sync extension point lets you cleanly and safely modify the Finder’s user interface to express file synchronization status and control. Unlike most extension points, Finder Sync does not add features to a host app. Instead, it lets you modify the behavior of the Finder itself.
Finder Sync Extensions
With a Finder Sync extension you register one or more folders for the system to monitor. Your Finder Sync extension then sets badges, labels, and contextual menus for any items in the monitored folders. You can also use the extension point’s API to add a toolbar button to the Finder window or a sidebar icon for the monitored folder.
Finder Sync supports apps that synchronize the contents of a local folder with a remote data source. It improves user experience by providing immediate visual feedback directly in the Finder. Badges display the sync state of each item, and contextual menus let users manage folder contents. Custom toolbar buttons can invoke global actions, such as opening a monitored folder or forcing a sync operation.
Note
The Finder Sync extension point lets you modify an item’s appearance in the Finder. It does not provide support for syncing the files. You are responsible for creating your own syncing component.
A Finder Sync extension can:
Before You Begin
Make sure the Finder Sync extension point is appropriate for the functionality you plan to provide. The best Finder Sync extensions support apps that sync the contents of a local folder with a remote data source. Finder Sync is not intended as a general tool for modifying the Finder’s user interface.
To learn about other types of app extensions you can create, see Table 1-1 in App Extensions Increase Your Impact.
Creating a Finder Sync Extension in Xcode
To create a Finder Sync extension, add a new target to your OS X project using the Finder Sync Extension template. This template contains a custom subclass of the
FIFinderSync class. This subclass acts as your extension’s primary class. The system automatically instantiates this class and calls the protocol methods in response to user actions.
For detailed information on adding extensions, see Creating an App Extension.
Set the Required Property List Values
For OS X to recognize and automatically load the Finder Sync extension, the extension target’s
info.plist file must contain the following entries:
In particular, the
NSExtensionPrincipalClass key must provide the name of your FIFinderSync subclass. The system automatically instantiates this class when the Finder first launches. It instantiates an additional copy whenever an Open or Save dialog is displayed. Each copy runs in its own process.
The Finder Sync Extension Xcode template configures these
Info.plist keys automatically. If you want to change the principal class, modify the value of the NSExtensionPrincipalClass key.
Specify Which Folders to Monitor
You specify the folders you want to monitor in your Finder Sync extension’s
init method, using the default FIFinderSyncController object. In most cases, you want to let the user specify these folders in UI provided by the containing app. You can pass this data between the containing app and your Finder Sync extension using shared user defaults.
![]()
To enable shared user defaults, first add both your Finder Sync extension and its containing app to an app group. This group creates a shared container that both processes can access. For each target, open the Xcode capabilities pane and turn on the App Groups capability. Provide a unique identifier for the shared group. Be sure to use the same identifier for both the Finder Sync extension and the containing app.
This process adds a
com.apple.security.application-groups entry to the targets’ entitlements.
For more information about app groups, see Adding an App to an App Group.
Next, instantiate a new
NSUserDefaults object by calling initWithSuiteName: and passing in the shared group’s identifier. This init method creates a user default object that loads and saves data to the shared container.
Set Up Badge Images![]()
Create your badge images so that each can be drawn at up to 320x320 pixels. For each image, fill the entire frame edge-to-edge with your artwork (in other words, use no padding). The system determines the size and placement of a badge image on a monitored item. The pixel size ranges at which your badge might be displayed are as follows:
To add a badge image to your Finder Sync controller’s configuration, use the
setBadgeImage:label:forBadgeIdentifier: method, as shown here:
You would typically do this in the sync controller’s initialization method. You can set up as many badge images as you need. The badge identifier string that you specify here allows you to later retrieve the image for applying it to a monitored item, as described in A Typical Finder Sync Use Case.
Implement FIFinderSync methodsFile Sync App For Mac Computer
The
FIFinderSync protocol declares a number of methods that you can implement to monitor and control the Finder. These methods let you receive notifications when the user observes monitored items, add contextual menus to monitored items, and add custom toolbar and sidebar icons.
Receiving Notifications When Users Observe Monitored Items
Implement these methods to receive notifications as the user browses through the contents of the monitored folders.
Adding Contextual Menu Items
Implement the
menuForMenuKind: method to provide a custom contextual menu. The menu argument indicates the type of menu that your extension should create. Each menu kind corresponds to a different type of user interaction.
You can get additional information about the currently selected items using the Finder Sync controller’s
targetedURL and selectedItemURLs methods. The targetedURL method returns the URL of the file or folder that the user Control-clicked. The selectedItemURLs method returns an array containing the URLs of all the currently selected items in the Finder window.
targetedURL and selectedItemURLs return valid values only inside the menuForMenuKind: method or inside one of its menu actions. If the user is not browsing the monitored folder (for example, if the user clicked the toolbar button while outside the monitored folder), both of these methods return nil .
Adding a Custom Toolbar Button
To add a custom toolbar button to the Finder window, implement the getter methods for the following properties:
When the user clicks the toolbar button, the system calls your primary class’s
menuForMenuKind: method, passing FIMenuKindToolbarItemMenu as the menu kind. Your extension must return an appropriate menu. The system then displays this menu.
Adding a Sidebar Icon
You can provide a custom sidebar icon for any of the root folders your extension is monitoring. If the user drags one of these root folders into the Finder’s sidebar, your icon will be displayed instead of the default folder icon.
To provide a custom sidebar icon, add the icons to your containing app. For this to work, both your app’s icons and the sidebar icons must be included in an inconset. If you are using an asset catalog to manage your app’s icons, you will need to switch to an iconset.
To create an iconset
Box Sync For Mac
Note
The sidebar icons you provide will replace the default folder icons in the Finder’s sidebar for any of the root folders that your extension is monitoring. This icon does not replace the icon for any folders contained by your monitored folder. It also does not replace the icon for any system folders that you may be monitoring (for example, Documents, Desktop, Applications, and Downloads).
A Typical Finder Sync Use CaseMac Sync Software
This section presents a typical use case. Your app manages and badges all the items inside the monitored folder. Because the user can populate the monitored folder with an arbitrary number of subfolders and files, the list of monitored items could grow to be very large. You must therefore consider the performance implications of adding and updating all of these badges. Specifically, avoid adding or updating the badge of any item that is not currently visible.
When dealing with a potentially large number of items, always provide the badges on demand. Provide badges to items only as they appear in the Finder window, and record all the URLs for the badges you set, so that you can update them as necessary.
Performance Concerns
Finder Sync extensions may have a much longer lifespan than most other extensions. Because of this long lifespan, you must take particular care to avoid any possible performance issues. Ideally, Finder Sync extensions should spend most of their time running but idle. Limit the number of resources the extension consumes. Most important, be sure to avoid leaking any resources. Over time, even a small trickle can grow into a serious problem.
The system may also launch additional copies of your extension whenever an Open or Save dialog is displayed. This means that the user may have multiple copies of your extension running at once, and some may be very short lived. Therefore, it’s generally best if the extension focuses on handling the badges, contextual menus, and toolbar buttons. Place in a separate service (a Login Item or Launch Agent) any code that performs the sync, updates state, or communicates with remote data sources. This approach ensures that there is only one syncing service running at a time.
For more information about communicating with the login item or launchd agent, see Using the Objective-C NSXPCConnection API in Daemons and Services Programming Guide.
