SPUStandardUserDriverDelegate

Objective-C

@protocol SPUStandardUserDriverDelegate <NSObject>

Swift

protocol SPUStandardUserDriverDelegate : NSObjectProtocol

A protocol for Sparkle’s standard user driver’s delegate

This includes methods related to UI interactions

  • Called before showing a modal alert window, to give the opportunity to hide attached windows that may get in the way.

    Declaration

    Objective-C

    - (void)standardUserDriverWillShowModalAlert;

    Swift

    optional func standardUserDriverWillShowModalAlert()

  • Called after showing a modal alert window, to give the opportunity to hide attached windows that may get in the way.

    Declaration

    Objective-C

    - (void)standardUserDriverDidShowModalAlert;

    Swift

    optional func standardUserDriverDidShowModalAlert()

  • Returns an object that formats version numbers for display to the user. If you don’t implement this method or return nil, the standard version formatter will be used.

    Declaration

    Objective-C

    - (id<SUVersionDisplay> _Nullable)standardUserDriverRequestsVersionDisplayer;

    Swift

    optional func standardUserDriverRequestsVersionDisplayer() -> SUVersionDisplay?

  • Decides whether or not the standard user driver should provide an option to show full release notes to the user.

    When a user checks for new updates and no new update is found, Sparkle by default will offer to show the application’s version history to the user by providing a “Version History” button in the no new update available alert.

    If this delegate method is implemented to return NO, then Sparkle will not provide an option to show full release notes to the user.

    Declaration

    Objective-C

    - (BOOL)standardUserDriverShouldShowVersionHistoryForAppcastItem:
    (nonnull SUAppcastItem *)item;

    Swift

    optional func standardUserDriverShouldShowVersionHistory(for item: SUAppcastItem) -> Bool

    Parameters

    item

    The appcast item corresponding to the latest version available.

    Return Value

    YES to allow Sparkle to show full release notes to the user, otherwise NO to disallow this.

  • Handles showing the full release notes to the user.

    When a user checks for new updates and no new update is found, Sparkle will offer to show the application’s version history to the user by providing a “Version History” button in the no new update available alert.

    If this delegate method is not implemented, Sparkle will instead offer to open the fullReleaseNotesLink (or releaseNotesLink if the former is unavailable) from the appcast’s latest item in the user’s web browser.

    If this delegate method is implemented, Sparkle will instead ask the delegate to show the full release notes to the user. A delegate may want to implement this method if they want to show in-app or offline release notes.

    Declaration

    Objective-C

    - (void)standardUserDriverShowVersionHistoryForAppcastItem:
    (nonnull SUAppcastItem *)item;

    Swift

    optional func standardUserDriverShowVersionHistory(for item: SUAppcastItem)

    Parameters

    item

    The appcast item corresponding to the latest version available.

  • Specifies whether or not the download, extraction, and installing status windows allows to be minimized.

    By default, the status window showing the current status of the update (download, extraction, ready to install) is allowed to be minimized for regular application bundle updates.

    Declaration

    Objective-C

    - (BOOL)standardUserDriverAllowsMinimizableStatusWindow;

    Swift

    optional func standardUserDriverAllowsMinimizableStatusWindow() -> Bool

    Return Value

    YES if the status window is allowed to be minimized (default behavior), otherwise NO.

  • Declares whether or not gentle scheduled update reminders are supported.

    The delegate may implement scheduled update reminders that are presented in a gentle manner by implementing one or both of: -standardUserDriverWillHandleShowingUpdate:forUpdate:state: and -standardUserDriverShouldHandleShowingScheduledUpdate:andInImmediateFocus:

    Visit https://sparkle-project.org/documentation/gentle-reminders for more information and examples.

    Declaration

    Objective-C

    @optional
@property (nonatomic, readonly) BOOL supportsGentleScheduledUpdateReminders;

    Swift

    optional var supportsGentleScheduledUpdateReminders: Bool { get }

    Return Value

    YES if gentle scheduled update reminders are implemented by standard user driver delegate, otherwise NO (default).

  • Specifies if the standard user driver should handle showing a new scheduled update, or if its delegate should handle showing the update instead.

    If you implement this method and return NO the delegate is then responsible for showing the update, which must be implemented and done in -standardUserDriverWillHandleShowingUpdate:forUpdate:state: The motivation for the delegate being responsible for showing updates is to override Sparkle’s default behavior and add gentle reminders for new updates.

    Returning YES is the default behavior and allows the standard user driver to handle showing the update.

    If the standard user driver handles showing the update, immediateFocus reflects whether or not it will show the update in immediate and utmost focus. The standard user driver may choose to show the update in immediate and utmost focus when the app was launched recently or the system has been idle for some time.

    If immediateFocus is NO the standard user driver may want to defer showing the update until the user comes back to the app. For background running applications, when immediateFocus is NO the standard user driver will always want to show the update alert immediately, but behind other running applications or behind the app’s own windows if it’s currently active.

    There should be no side effects made when implementing this method so you should just return YES or NO You will also want to implement -standardUserDriverWillHandleShowingUpdate:forUpdate:state: for adding additional update reminders.

    This method is not called for user-initiated update checks. The standard user driver always handles those.

    Visit https://sparkle-project.org/documentation/gentle-reminders for more information and examples.

    Declaration

    Objective-C

    - (BOOL)standardUserDriverShouldHandleShowingScheduledUpdate:
            (nonnull SUAppcastItem *)update
                                         andInImmediateFocus:
                                             (BOOL)immediateFocus;

    Swift

    optional func standardUserDriverShouldHandleShowingScheduledUpdate(_ update: SUAppcastItem, andInImmediateFocus immediateFocus: Bool) -> Bool

    Parameters

    update

    The update the standard user driver should show.
    immediateFocus

    If immediateFocus is YES, then the standard user driver proposes to show the update in immediate and utmost focus. See discussion for more details.

    Return Value

    YES if the standard user should handle showing the scheduled update (default behavior), otherwise NO if the delegate handles showing it.

  • Called before an update will be shown to the user.

    If the standard user driver handles showing the update, handleShowingUpdate will be YES. Please see -standardUserDriverShouldHandleShowingScheduledUpdate:andInImmediateFocus: for how the standard user driver may handle showing scheduled updates when handleShowingUpdate is YES and state.userInitiated is NO.

    If the delegate declared it handles showing the update by returning NO in -standardUserDriverShouldHandleShowingScheduledUpdate:andInImmediateFocus: then the delegate should handle showing update reminders in this method, or at some later point. In this case, handleShowingUpdate will be NO. To bring the update alert in focus, you may call -[SPUStandardUpdaterController checkForUpdates:] or -[SPUUpdater checkForUpdates]. You may want to show additional UI indicators in your application that will show this update in focus and want to dismiss additional UI indicators in -standardUserDriverWillFinishUpdateSession or -standardUserDriverDidReceiveUserAttentionForUpdate:

    If state.userInitiated is YES then the standard user driver always handles showing the new update and handleShowingUpdate will be YES. In this case, it may still be useful for the delegate to intercept this method right before a new update will be shown.

    This method is not called when bringing an update that has already been presented back in focus.

    Visit https://sparkle-project.org/documentation/gentle-reminders for more information and examples.

    Declaration

    Objective-C

    - (void)
    standardUserDriverWillHandleShowingUpdate:(BOOL)handleShowingUpdate
                                    forUpdate:(nonnull SUAppcastItem *)update
                                        state:
                                            (nonnull SPUUserUpdateState *)state;

    Swift

    optional func standardUserDriverWillHandleShowingUpdate(_ handleShowingUpdate: Bool, forUpdate update: SUAppcastItem, state: SPUUserUpdateState)

    Parameters

    handleShowingUpdate

    YES if the standard user driver handles showing the update, otherwise NO if the delegate handles showing the update.
    update

    The update that will be shown.
    state

    The user state of the update which includes if the update check was initiated by the user.

  • Called when a new update first receives attention from the user.

    This occurs either when the user first brings the update alert in utmost focus or when the user makes a choice to install an update or dismiss/skip it.

    This may be useful to intercept for dismissing custom attention-based UI indicators (e.g, user notifications) introduced when implementing -standardUserDriverWillHandleShowingUpdate:forUpdate:state:

    For custom UI indicators that need to still be on screen after the user has started to install an update, please see -standardUserDriverWillFinishUpdateSession.

    Declaration

    Objective-C

    - (void)standardUserDriverDidReceiveUserAttentionForUpdate:
    (nonnull SUAppcastItem *)update;

    Swift

    optional func standardUserDriverDidReceiveUserAttention(forUpdate update: SUAppcastItem)

    Parameters

    update

    The new update that the user gave attention to.

  • Called before the standard user driver session will finish its current update session.

    This may occur after the user has dismissed / skipped a new update or after an update error has occurred. For updaters updating external/other bundles, this may also be called after an update has been successfully installed.

    This may be useful to intercept for dismissing custom UI indicators introduced when implementing -standardUserDriverWillHandleShowingUpdate:forUpdate:state:

    For UI indicators that need to be dismissed when the user has given attention to a new update alert, please see -standardUserDriverDidReceiveUserAttentionForUpdate:

    Declaration

    Objective-C

    - (void)standardUserDriverWillFinishUpdateSession;

    Swift

    optional func standardUserDriverWillFinishUpdateSession()
