HUBContentOperationWithInitialContent

@protocol HUBContentOperationWithInitialContent <HUBContentOperation>

Extended Hub content operation protocol that adds the ability to add initial content to a view

Use this protocol whenever your content operation is able to add pre-loaded content to a view, that is rendered before the main content loading chain is started.

See HUBContentOperation for more information.


                    
                    
                    -addInitialContentForViewURI:toViewModelBuilder:

Add any initial content for a view with a certain view URI, using a view model builder

Initial content is always loaded synchronously, and is displayed for the user before the real view model of a view is loaded. It can be used to display a skeleton version of the final User Interface, or to add placeholder content. The key for this method is speed - it shouldn’t be used to perform expensive operations or to load any final content.

In case no relevant content can be added by the content operation, it can just implement this method as a no-op.

Declaration

Objective-C

- (void)addInitialContentForViewURI:(nonnull NSURL *)viewURI
                 toViewModelBuilder:
                     (nonnull id<HUBViewModelBuilder>)viewModelBuilder;

Parameters

`viewURI`	The URI of the view that initial content should be added for
`viewModelBuilder`	The builder that can be used to add initial content
